The statement "In reality, when a circuit is first connected to a power source the current through the circuit does not jump discontinuously from zero to its maximum value" is True.

This is because the behavior of an electrical circuit is governed by the principles of electromagnetism, which include the laws of induction and capacitance. When a circuit is first connected to a power source, the voltage across the circuit changes instantaneously from zero to its maximum value, which can cause a transient response in the circuit. This transient response can cause the current in the circuit to increase rapidly, but it does not jump discontinuously from zero to its maximum value.

The rate of change of current in the circuit is determined by the inductance and capacitance of the circuit. An inductor resists changes in the current flow through a circuit, while a capacitor resists changes in the voltage across a circuit. These properties cause the current in the circuit to increase gradually until it reaches its steady-state value.

In addition, the resistance of the circuit also affects the rate of change of current. A circuit with high resistance will have a slower rate of change of current compared to a circuit with low resistance.

Therefore, the current in a circuit does not jump discontinuously from zero to its maximum value when the circuit is first connected to a power source due to the principles of electromagnetism and the properties of the circuit components.

If the mass is doubled, the period of the pendulum would increase to approximately 2.41 seconds.

The formula for the period of a simple pendulum is T = 2π√(l/g), where T is the period, l is the length of the pendulum, and g is the acceleration due to gravity. We can rearrange this formula to solve for g:

g = (4π²l) / T²

Plugging in the given values, we get:

g = (4π² x 0.82 m) / (1.70 s)²
g ≈ 18.6 m/s²

Now, if we double the mass of the pendulum to 4.00 kg, the period can be found using the same formula:

T = 2π√(l/g), where g is the value we just calculated and l is still 0.82 m, but the mass is now 4.00 kg.

T = 2π√(0.82 m / 18.6 m/s²) ≈ 2.41 s

Therefore, the period of the pendulum would increase to approximately 2.41 seconds if the mass is doubled.

Answer:No, the calculation you provided is incorrect. To find the relative speed of asteroid 1 with respect to asteroid 2, we need to use the relativistic velocity addition formula:

v = (v1 - v2) / (1 - v1*v2/c^2)

where v1 is the velocity of asteroid 1 relative to Earth, v2 is the velocity of asteroid 2 relative to Earth, and c is the speed of light.

Substituting the given values, we get:

v = (0.81c - 0.59c) / (1 - 0.81c * 0.59c / c^2)

v = 0.22c / (1 - 0.48)

v = 0.42c

Therefore, the speed of asteroid 1 relative to asteroid 2 is 0.42 times the speed of light (c).

Explanation:

The answer  is that the fraction of your own mass that is due solely to electrons is very small.

In fact, electrons are so tiny that they contribute only a tiny fraction to the total mass of an atom. The majority of the mass of an atom comes from the protons and neutrons that make up the nucleus.

Electrons are negatively charged particles that orbit the nucleus of an atom. They have a very small mass compared to protons and neutrons, which are much larger and heavier particles found in the nucleus. The mass of an electron is approximately 1/1836th the mass of a proton or neutron.

Therefore, the fraction of your own mass that is due solely to electrons is very small, on the order of a few percent or less. The vast majority of your mass comes from the protons and neutrons in your body's atoms. So while electrons are essential for the chemical reactions that sustain life, they do not contribute significantly to our overall mass.

where R is the resistance,
XL is the inductive reactance, and
XC is the capacitive reactance.

When a roller coaster reaches a velocity of 65.0 m/s prior to the ascent of a hill, the maximum height that can be reached without any propulsion is approximately 213.6 meters.

This assumes that there is no energy loss from friction. The energy conservation principle governs the maximum height reached by a roller coaster. At the base of the hill, the roller coaster has kinetic energy (energy of motion), but no potential energy (energy of height). It has the maximum potential energy and minimum kinetic energy at the highest point of the hill, and it returns to the base of the hill with zero potential energy and maximum kinetic energy. The total energy, which is the sum of potential energy and kinetic energy, is always conserved, implying that the energy at the base of the hill equals the energy at the peak of the hill. According to the principle of conservation of energy:Ei = Efwhere Ei is the initial energy, Ef is the final energy, and E = KE + PE, where KE is kinetic energy, and PE is potential energy.Consider the roller coaster with a velocity of 65.0 m/s at the base of the hill. The initial energy of the roller coaster, Ei = KE + PE, is equal to: Ei = (1/2) mv^2 + 0where m is the mass of the roller coaster and v is its velocity. Ei = (1/2) mv^2The final energy of the roller coaster at the highest point on the hill, Ef, is equal to: Ef = 0 + mghwhere h is the height of the roller coaster at the top of the hill.

Equating Ei and Ef:(1/2) mv^2 = mgh

Solving for h, we get: h = (1/2) v^2/g

where g is the acceleration due to gravity.The maximum height that can be attained by a roller coaster without propulsion is h = (1/2) v^2/g.

Substituting v = 65.0 m/s and g = 9.81 m/s²,

we get: h = (1/2) (65.0 m/s)^2/9.81 m/s² = 213.6 meters.

Therefore, the maximum height that a roller coaster can reach without propulsion is around 213.6 meters, given no friction.

Air-vapor mixture at a pressure of 235 kpa has a dry-bulb temperature of 30 c and a wet-bulb temperature of 20 c, the relative humidity in percentage is 33.5%.

Air contains water vapor in the form of moisture. The amount of water vapor that air can hold is dependent on the temperature and pressure of the air. Relative humidity is the ratio of the amount of water vapor in the air to the maximum amount of water vapor the air can hold at a given temperature and pressure, expressed as a percentage.

To determine the relative humidity of an air-vapor mixture, we need to know the dry-bulb temperature, wet-bulb temperature, and pressure. The dry-bulb temperature is the ambient temperature measured by a regular thermometer, while the wet-bulb temperature is measured using a thermometer with a wet wick or cloth wrapped around its bulb. The wet-bulb temperature measures the temperature at which water evaporates from the wick, which is an indicator of the humidity of the air.

Using the given values, we can use a psychrometric chart or equations to calculate the relative humidity. However, using the simpler formula, we have:

   Calculate the saturation vapor pressure at the dry-bulb temperature:

       From a steam table, the saturation vapor pressure at 30°C is 4.246 kPa.

   Calculate the vapor pressure at the wet-bulb temperature:

       From a psychrometric chart or equations, the vapor pressure at 20°C with a wet-bulb depression of 10°C is 1.423 kPa.

   Calculate the relative humidity:

       Relative humidity = (vapor pressure / saturation vapor pressure) x 100%

       Relative humidity = (1.423 kPa / 4.246 kPa) x 100% = 33.5%

The final angular velocity of the flywheel after it has rotated through a certain angle θ can be given by ω = sqrt(2(1.7/10.0768)(1 - e^-0.12θ)θ).

The given information describes a flywheel with a mass of 52 kg and a radius of gyration of 0.46 m about its shaft axis. The torque applied to the flywheel is given by the function m = 1.7(1 - e^-0.12θ), where θ is in radians.

If the flywheel is at rest, then its initial angular velocity is zero. To find the angular acceleration of the flywheel, we can use the formula:

m = Iα

where m is the torque, I is the moment of inertia, and α is the angular acceleration.

The moment of inertia of a flywheel can be calculated using the formula:

I = mk²

where k is the radius of gyration.

Substituting the given values, we get:

I = (52 kg)(0.46 m)² = 10.0768 kg m²

Now, we can rewrite the torque equation as:

α = m/I = (1.7/I)(1 - e^-0.12θ)

Substituting the moment of inertia, we get:

α = (1.7/10.0768)(1 - e^-0.12θ)

This equation gives us the angular acceleration of the flywheel at any given angle θ. If we want to find the final angular velocity of the flywheel after it has rotated through a certain angle, we can use the formula:

ω² - ω0² = 2αθ

where ω is the final angular velocity, ω0 is the initial angular velocity (which is zero in this case), α is the angular acceleration, and θ is the angle rotated through.

Solving for ω, we get:

ω = sqrt(2αθ)

Substituting the expression for α, we get:

ω = sqrt(2(1.7/10.0768)(1 - e^-0.12θ)θ)

The net flux is 3.01 × 10⁴ Nm²/C. flux through one face is 5.01 × 10³ Nm²/C

a) The electric flux through the surface of the cube, Φ, can be expressed using Gauss's law as:

Φ = ∫∫ E · dA = q_enc / ε_0

where q_enc is the charge enclosed by the surface, ε_0 is the electric constant, and the integral is taken over the closed surface of the cube. Since the charge q is inside the cube and is enclosed by all six faces, we have:

q_enc = q

The area of each face is A = L², where l is the side length of the cube. Therefore, the total area of the cube's surface is 6A. Substituting these values, we obtain:

Φ = q / ε_0 = (26.7 μC) / (8.85 × 10⁻¹² Nm²/C²) ≈ 3.01 × 10⁴ Nm²/C

b) If the charge is at the center of the cube, the electric field E due to the charge is radially symmetric and has the same magnitude at every point on the surface of the cube. But, the electric flux through any one of the faces is 1/6 times the flux through the entire surface of the cube, which is given by:

Φ = q / 6ε_0 ≈ (3.01 × 10⁴)/6 Nm²/C = 5.01 × 10³ Nm²/C

c) For a regular polyhedron with n faces, if the charge q is located at the center of the polyhedron, the electric flux through a single face can be expressed as:

Φ = ∫∫ E · dA = q_enc / ε_0

where q_enc is the charge enclosed by the surface of the face. Since the charge is distributed symmetrically throughout the polyhedron, each face encloses an equal fraction of the total charge:

q_enc = q / n

The area of each face is identical and given by A. Therefore, the total area of the polyhedron's surface is nA. Substituting these values, we obtain:

Φ = q_enc / ε_0 = (q / n) / ε_0 = q / (nε_0)

the thickness of the atmosphere is 1.80 km.

According to special relativity, time appears to pass slower for a moving object than for an object at rest. This effect is known as time dilation. In the case of the muon traveling through the atmosphere at a high speed of 0.9998 c, time appears to pass slower for the muon compared to an observer on the ground.

Using the formula for time dilation, we can calculate the time experienced by the muon as it travels through the atmosphere:

t_muon = t_observer / gamma

where t_observer is the time measured by an observer on the ground and gamma is the Lorentz factor given by:

gamma = 1 / sqrt(1 - v^2/c^2)

where v is the speed of the muon and c is the speed of light.

Plugging in the values, we get:

gamma = 1 / sqrt(1 - 0.9998^2) = 10.01

t_muon = t_observer / gamma = (60 km / 0.9998 c) / 10.01 = 5.992 microseconds

Therefore, the thickness of the atmosphere according to the muon is:

d_muon = v * t_muon = 0.9998 c * 5.992 microseconds = 1.80 km

To determine the thickness of the atmosphere according to the muon, we'll need to apply the concept of length contraction. Length contraction occurs when an object travels at a significant fraction of the speed of light (c), causing its observed length to contract.

Given that the muon travels at a speed of 0.9998c, we can calculate the Lorentz factor (γ) using the equation:

γ = 1 / √(1 - v²/c²)

Where v is the speed of the muon (0.9998c) and c is the speed of light.

γ = 1 / √(1 - (0.9998c)²/c²)
γ ≈ 16.1

Now, we can calculate the thickness of the atmosphere according to the muon using the length contraction equation:

L' = L / γ

Where L' is the contracted length (thickness of the atmosphere according to the muon), L is the actual length (60 km), and γ is the Lorentz factor.

L' = 60 km / 16.1
L' ≈ 3.73 km

So, according to the muon, the thickness of the atmosphere is approximately 3.73 km.

The behavior described in this question is best explained by Pascal's principle.

Pascal's principle states that a change in pressure applied to an enclosed fluid is transmitted undiminished to every point of the fluid and to the walls of the container. In this case, the pressure applied by the membrane-covered funnel is transmitted to the liquid in the u-shaped tube, causing the liquid to rise on one side and fall on the other side to maintain equilibrium. The height of the liquid in the u-shaped tube remains constant because the pressure is distributed evenly throughout the fluid. Bernoulli's principle and irrotational flow are more applicable to fluid dynamics in pipes and around objects, while the continuity equation deals with the conservation of mass in a fluid. Archimedes' principle, on the other hand, relates to buoyancy and the upward force exerted on an object in a fluid.

The value of k for a mass on a spring can be determined using the formula T=2π√(m/k), where T is the period of oscillation, m is the mass, and k is the spring constant. In this problem, we know that the mass is 51.7 grams and that 21 cycles took 3.42 seconds, which means that the period of oscillation is T=3.42/21=0.163 seconds. Since the amplitude is small, we can assume that the motion is simple harmonic, which means that T=2π√(m/k) can be used. Rearranging this formula gives k=m(2π/T)^2, which gives k=51.7(2π/0.163)^2=76.8 N/m.

To show that a hammer dropped from the roof of a two-story building does more work than a hammer falling from a coffee table, we can compare the gravitational potential energy converted to kinetic energy for each case.

The work done on an object is equal to the change in its energy. In this case, the work done is equal to the change in gravitational potential energy as the hammers fall.

The gravitational potential energy is given by the equation:

PE = mgh

Where PE is the potential energy, m is the mass, g is the acceleration due to gravity (approximately 9.8 m/s²), and h is the height.

For the hammer dropped from the two-story building roof:

PE1 = (0.2 kg) * (9.8 m/s²) * (10 m)

PE1 = 19.6 J

For the hammer falling from the coffee table:

PE2 = (0.2 kg) * (9.8 m/s²) * (1.2 m)

PE2 = 2.352 J

From the calculations, we can see that the potential energy for the hammer dropped from the two-story building roof (19.6 J) is significantly higher than the potential energy for the hammer falling from the coffee table (2.352 J).

To solve this problem, we need to use the principles of Newton's laws of motion and rotational dynamics.

a. To determine FT1 and FT2, we can use the equation for the net force in the direction of motion of each block. For block m1, the net force is:

FT1 - m1g = m1a

where g is the acceleration due to gravity and a is the acceleration of the blocks. Solving for FT1, we get:

FT1 = m1(g + a)

Substituting the values given in the problem, we get:

FT1 = 7.96(9.81 + 1) = 87.4 N

For block m2, the net force is:

m2g - FT2 = m2a

Solving for FT2, we get:

FT2 = m2(g - a)

Substituting the values given in the problem, we get:

FT2 = 10(9.81 - 1) = 88.1 N

Therefore, the tensions in the two parts of the string are:

FT1 = 87.4 N and FT2 = 88.1 N

b. To find the net torque T acting on the pulley and determine its moment of inertia I, we can use the equation for the torque due to a force acting at a distance from the axis of rotation. In this case, the tension in the string exerts a force on the pulley, causing it to rotate.

The torque due to FT1 is:

τ1 = FT1r

where r is the radius of the pulley. The torque due to FT2 is:

τ2 = -FT2r

where the negative sign indicates that the torque is in the opposite direction to τ1.

The net torque T acting on the pulley is the sum of τ1 and τ2:

T = τ1 + τ2 = (FT1 - FT2)r

Substituting the values we found earlier, we get:

T = (87.4 - 88.1)(0.029) = -0.02 Nm

Since the blocks are accelerating to the right, the pulley must be accelerating to the left. Therefore, the net torque T must be negative.

To determine the moment of inertia I of the pulley, we can use the equation for the torque due to the acceleration of a rotating object:

T = Iα

where α is the angular acceleration of the pulley. Since the pulley is not sliding or slipping, we know that the linear acceleration of the blocks is equal to the tangential acceleration of the pulley, which is given by:

a = rα

where a is the linear acceleration of the blocks and r is the radius of the pulley.

Substituting for α in the equation for torque, we get:

T = I(a/r)

Rearranging, we get:

I = (Tr)/a

Substituting the values we found earlier, we get:

I = (-0.02)(0.029)/1 = -0.00058 kgm^2

Since the moment of inertia cannot be negative, we know that we made an error in our calculation. The most likely cause is a sign error in the torque calculation. We should check our work and try again to find the correct value of I.

The height (y) of the pistol is 94 meters. To explain, we can use the fact that the horizontal and vertical motions are independent of each other.

To explain, we can use the fact that the horizontal and vertical motions are independent of each other. Since the bullet is fired horizontally, its initial vertical velocity is zero. We can use the equation for vertical motion:

[tex]y = (1/2)gt^2[/tex]

where y is the vertical displacement, g is the acceleration due to gravity (approximately 9.8 m/s^2), and t is the time of flight.

The time of flight can be calculated using the horizontal distance and the horizontal velocity:

[tex]t = d/v[/tex]

where d is the horizontal distance (196 m) and v is the horizontal velocity (356 m/s).

Substituting the values, we get:

[tex]t = 196 m / 356 m/s ≈ 0.551 seconds[/tex]

Plugging this value into the equation for vertical motion, we find:

y = (1/2)(9.8 m/s^2)(0.551 s)^2 ≈ 94 meters.

The acid dissociation constant Ka of the acid is 2.48 x 10⁻⁸ M.

The pH of a solution is related to the concentration of H+ ions by the equation:

pH = -log[H⁺]

We know that the pH of the solution is 4.48, so we can find the concentration of H+ ions:

[H+] = [tex]10^(^-^p^H^) = 10^(^-^4^.^4^8^) = 3.52 x 10^(^-^5^) M[/tex]

Since the acid is 0.050 dissociated, the concentration of the undissociated acid is:

[HA] = 0.050 M

The dissociation reaction of the acid can be written as:

HA(aq) ⇌ H+(aq) + A-(aq)

The acid dissociation constant Ka is defined as:

Ka = [H+(aq)][A-(aq)]/[HA(aq)]

At equilibrium, the concentration of H+ ions and A- ions is equal to each other, so we can write:

Ka = [H+(aq)]²/[HA(aq)] = (3.52 x 10⁻⁵)²/0.050 = 2.48 x 10⁻⁸ M

The voltage across the capacitor in an RLC circuit after two periods can be determined using the equation:

Vc(t) = V0*e^(-t/RC)*cos(wt + phi)

where V0 is the initial voltage across the capacitor, R is the resistance, C is the capacitance, and w is the angular frequency of the circuit. The parameter phi represents the phase angle between the voltage and current in the circuit.

To calculate the voltage across the capacitor after two periods, we need to first determine the time period of the circuit. The time period can be calculated using the formula T = 2*pi/w, where w = 1/(sqrt(LC)) is the angular frequency of the circuit, L is the inductance of the circuit, and C is the capacitance.

Once we have determined the time period, we can calculate the voltage across the capacitor after two periods using the equation above. However, the value of phi is not given, so we cannot calculate the exact value of Vc(t) after two periods.

In general, the quality factor of an RLC circuit is defined as the ratio of the energy stored in the circuit to the energy lost per cycle. A higher quality factor implies that the circuit can store more energy per cycle and thus has a more narrow bandwidth. In this case, the quality factor is given as 4, which indicates that the circuit has a moderate amount of damping.

In summary, to calculate the voltage across the capacitor after two periods in an RLC circuit with a quality factor of 4, we need to determine the time period of the circuit and then use the equation for the voltage across the capacitor with the initial voltage V0 = 8 V. However, without knowing the phase angle phi, we cannot calculate the exact value of Vc(t) after two periods.

The collection of all possible outcomes of a probability experiment is called the sample space. It is a fundamental concept in probability theory and is used to determine the probability of an event occurring. The sample space represents all possible outcomes that can occur in a given situation.

For example, if a coin is flipped, the sample space consists of two possible outcomes – heads or tails. If a dice is rolled, the sample space consists of six possible outcomes – numbers 1 through 6. In more complex experiments, the sample space can be larger and more complicated.

The sample space can be expressed in different ways depending on the context and the experiment. It can be listed using set notation or represented graphically using a tree diagram or a Venn diagram.

Understanding the sample space is crucial for calculating probabilities and making informed decisions based on the results of a probability experiment.

Linear regression is taken on the temperature data only as the temperature begins to decrease because it helps to model the relationship between temperature and time accurately.

As temperature decreases, there is often a linear relationship between temperature and time, meaning that the temperature change per unit of time is consistent. By taking a linear regression on the temperature data during this period, we can estimate the rate of temperature decrease and make predictions about future temperature changes.

However, this linear relationship may not hold true for all temperature ranges. At high or low temperatures, other factors such as phase changes or chemical reactions may cause non-linear temperature changes. Therefore, it is important to analyze temperature data for different temperature ranges to determine the appropriate regression model.

The magnitude of the average angular acceleration is 0.104 [tex]rad/s^2[/tex] and the angle the average angular acceleration vector makes with the horizontal is approximately 1.14 degrees.

We can use the formula for average angular acceleration to solve this problem:

α_avg = (ω_f - ω_i) / t

where α_avg is the average angular acceleration, ω_i is the initial angular velocity, ω_f is the final angular velocity, and t is the time interval.

(a) First, we need to convert the initial and final angular velocities from rpm to rad/s:

ω[tex]_i[/tex] = 50 rpm x (2π rad/rev) x (1 min/60 s) = 5.24 rad/s

ω[tex]_f[/tex] = 65 rpm x (2π rad/rev) x (1 min/60 s) = 6.80 rad/s

Substituting these values into the formula, we get:

α[tex]_a_v_g[/tex] = (ω[tex]_f[/tex]- ω[tex]_i[/tex]) / t = (6.80 rad/s - 5.24 rad/s) / 15 s = 0.104 [tex]rad/s^2[/tex]

Therefore, the magnitude of the average angular acceleration is 0.104 [tex]rad/s^2[/tex].

(b) The angle the average angular acceleration vector makes with the horizontal can be found using trigonometry. Let's denote this angle by θ. We can use the following relationship:

tan(θ) =α[tex]_a_v_g[/tex]  / ω[tex]_i[/tex]

Substituting the values we found earlier, we get:

tan(θ) = 0.104[tex]rad/s^2[/tex] / 5.24 rad/s

tan(θ) = 0.0199

Taking the inverse tangent of both sides, we get:

θ = [tex]tan^(^-^1^)[/tex](0.0199) = 1.14 degrees

Therefore, the angle the average angular acceleration vector makes with the horizontal is approximately 1.14 degrees.

The maximum power a giant electric eel can deliver to its prey is 5.00×10^2 V × 1.00 A = 5.00 × 10^2 W. the current through the swimmer in this case is not large enough to be dangerous.

If the snorkeler's body resistance is 615 Ω and the eel delivers a voltage of 5.00×10^2 V, then the current flowing through the snorkeler's body can be calculated using Ohm's Law: I = V/R. Hence, I = (5.00×10^2 V) / (615 Ω) ≈ 0.813 A.

The current of 0.813 A is less than 500 mA, the threshold for causing heart fibrillation and death. Therefore, the current through the swimmer in this case is not large enough to be dangerous.

The power received by the snorkeler can be calculated using the formula P = IV. Thus, P = (0.813 A) × (5.00×10^2 V) ≈ 4.07 × 10^2 W.

A ball has a mass of 1. 2 kg and is raised to a height of 2 m. The ball has potential gravitational energy of approximately 23.52 Joules.

The potential gravitational energy of an object is given by the equation:

[tex]PE = m * g * h[/tex]

where PE is the potential energy, m is the mass of the object, g is the acceleration due to gravity, and h is the height.

The work done by gravitational force on the body is equal to the change in gravitational potential energy.

Work is equal to force times displacement. Since the mass is the same in both situations, the g and h constants are likewise the same in both situations. In all scenarios, the gravitational energy change will be the same. Initial velocity has no bearing at all on the outcome in the kinetic energy.

Plugging in the given values, we have:

PE = 1.2 kg * 9.8 m/s² * 2 m = 23.52 J

Therefore, the ball has potential gravitational energy of approximately 23.52 Joules when it is raised to a height of 2 meters.

True. In a well-sealed room, the specific humidity will increase as the temperature rises. This is because warm air can hold more moisture than cooler air.

As the temperature increases, the air molecules move faster and farther apart, creating more space for water vapor. This means that the amount of moisture in the air remains the same, but the ratio of moisture to dry air (specific humidity) increases.

For example, if a room has a specific humidity of 50% at a temperature of 70°F and the temperature rises to 80°F, the air can hold more moisture. The same amount of moisture will now only be 40% of the total volume of the air, leading to a specific humidity increase to 62.5%.

It is important to note that while an increase in temperature can lead to an increase in specific humidity, it does not necessarily mean that the air is more humid. Relative humidity, which takes into account the temperature and the amount of moisture in the air, is a better indicator of the actual level of moisture in the air.

The focal length of the concave mirror is -0.2 m and b) the height of the image is 0.111 m and it is inverted.

To find the focal length of the concave mirror, we can use the mirror equation: 1/f = 1/d_o + 1/d_i, where f is the focal length, d_o is the distance of the object from the mirror, and d_i is the distance of the image from the mirror. Plugging in the given values, we get 1/f = 1/1.8 + 1/0.2, which simplifies to f = -0.2 m (since the mirror is concave, the focal length is negative).
To find the height of the image, we can use the magnification equation: M = -d_i/d_o, where M is the magnification (negative for inverted images), d_i is the distance of the image from the mirror, and d_o is the distance of the object from the mirror. Plugging in the given values, we get M = -0.2/1.8 = -0.111. Since the magnification is negative, the image is inverted.
Finally, we can use the equation h_i = M*h_o, where h_i is the height of the image and h_o is the height of the object, to find the height of the image. Plugging in the given values and solving for h_i, we get h_i = -0.111*1 = -0.111 m. However, since the question asks for a positive number, we take the absolute value to get h_i = 0.111 m. Therefore, the height of the image is 0.111 m and it is inverted.
In summary, a) the focal length of the concave mirror is -0.2 m and b) the height of the image is 0.111 m and it is inverted.
