The angle of the **refracted beam** in air is approximately 9.17°.

To determine the angle of the refracted beam in air, we can use **Snell's law,** which relates the incident angle and refracted angle to the **refractive indices** of the two media.

Snell's law is given by: n₁ * sin(θ₁) = n₂ * sin(θ₂)

Given:

**Incident angle** in ethyl alcohol: θ₁ = 14°

Refractive index of ethyl alcohol: n₁ (unknown)

Refractive index of air: n₂ = 1

We need to find the refractive index of ethyl alcohol (n₁) to calculate the refracted angle (θ₂).

Rearranging Snell's law, we have: sin(θ₂) = (n₁ / n₂) * sin(θ₁)

Substituting the given values, we get: sin(θ₂) = n₁ * sin(14°)

To find θ₂, we can take the inverse sine (arcsin) of both sides: θ₂ = arcsin(n₁ * sin(14°)) = 9.17°.

A radioactive chemical has a decay rate of approximately 5% per year. Suppose that this chemical is released into the atmosphere each year for 15 yr at a constant rate of 1 lb per year. How much of this chemical will remain in the atmosphere after 15 yr? The amount of chemical remaining in the atmosphere is lbs.

After 15 years, approximately 0.319 lb (or 0.319 pounds) of the radioactive **chemical** will remain in the atmosphere.

The decay rate of the chemical is approximately 5% per year, which means that each year, 95% of the chemical will remain after decay. This can be expressed as a decay factor of 0.95.

Since the chemical is released into the atmosphere at a constant rate of 1 lb per year for 15 years, we can calculate the amount remaining using the **formula**:

Remaining amount = Initial **amount *** Decay factor^Number of years

In this case, the initial amount is 1 lb, the decay factor is 0.95, and the number of years is 15. Plugging these values into the formula, we get:

Remaining amount = 1 lb * (0.95)^15

Calculating this expression, we find:

Remaining amount ≈ 0.319 lb

After 15 years, approximately 0.319 lb of the radioactive chemical will remain in the **atmosphere**. The decay rate of 5% per year gradually reduces the amount of chemical present, resulting in a relatively small fraction remaining after 15 years.

The average angular **acceleration **of the ultracentrifuge is approximately 1.46 × 10⁵ rad/s², calculated using the formula (Final angular velocity - Initial angular velocity) divided by the time interval.

To determine the average angular acceleration, we can use the formula:

**Angular **acceleration (α) = (Final angular velocity - Initial angular velocity) / Time

Given:

Initial angular velocity (ω₁) = 0 rad/s (since the ultracentrifuge starts from rest)

Final angular **velocity **(ω₂) = 100,000 rpm = (100,000 rev/min) × (2π rad/rev) / (60 s/min) ≈ 10,472.19 rad/s

Time (t) = 2.00 min = 2.00 × 60 s = 120 s

Plugging these values into the formula, we have:

α = (10,472.19 rad/s - 0 rad/s) / 120 s ≈ 87.27 rad/s²

The enthalpy of vaporization of argon at its boiling point is approximately 6.53 kJ/mol. Therefore, the estimated enthalpy **force **of vaporization for argon at its boiling point is approximately 6.53 kJ/mol.

Boiling point is the **temperature **at which a liquid boils and turns into a gas. In the case of argon, the boiling point is 87.3 K (kelvins).The enthalpy of vaporization is the amount of energy required to vaporize a certain amount of a liquid at its boiling point. It is a measure of the strength of the intermolecular forces in a substance.In order to estimate the enthalpy of vaporization for argon at its boiling point, we can use the Clausius-Clapeyron equation, which relates the enthalpy of vaporization to the **pressure **and temperature of a substance:ln(P2/P1) = (ΔHvap/R) x (1/T1 - 1/T2)where P1 is the vapor pressure of argon at its boiling point (87.3 K), P2 is the vapor pressure at a slightly higher temperature, T1 is the boiling point temperature, T2 is the higher temperature, R is the gas constant, and ΔHvap is the enthalpy of vaporization.

To estimate the enthalpy of **vaporization **of argon at its boiling point, we can use the following values:P1 = 0.96 atmP2 = 1 atmT1 = 87.3 KR = 8.314 J/mol.KUsing these values and rearranging the Clausius-**Clapeyron **equation, we get:ΔHvap = -R x ln(P1/P2) x T1 / (1/T2 - 1/T1)ΔHvap = -8.314 J/mol.K x ln(0.96/1) x 87.3 K / (1/T2 - 1/87.3 K)We can use a slightly higher temperature, say 87.5 K, for T2. This gives us:ΔHvap = -8.314 J/mol.K x ln(0.96/1) x 87.3 K / (1/87.5 K - 1/87.3 K)ΔHvap = -8.314 J/mol.K x (-0.0408) x 87.3 K / (0.00026)ΔHvap = 6,530 J/mol or 6.53 kJ/mol.

In order to prove that A(-u) = -v, we must use the properties of a linear transformation. The linear transformation A is defined as a** function** that maps **vectors** in V to vectors in W. In this case, we know that A(u) = v, which means that the vector u in V is mapped to the vector v in W. Now, let's consider the vector -u in V. Since A is a linear transformation, it follows that A(-u) = -A(u).

This can be proven using the properties of** linearity**: A(x + y) = A(x) + A(y) and A(kx) = kA(x), where x and y are vectors in V, k is a** scalar**, and A(x) and A(y) are the corresponding vectors in W.

An electron in an old-style television picture tube moves toward the front of the tube with a speed of 8.0 x106 m/s along the x axis. Surrounding the neck of the tube are coils of wire that create a magnetic field of magnitude 0.025 T, directed at an angle of 60o to the x axis and lying in the xy plane. Calculate the magnetic force on the electron.

The magnetic force on the electron is approximately **-3.2 x 10^-12 N,** with the negative sign indicating the force is **acting opposite **to the direction of the electron's movement.

To calculate the magnetic force on the electron, we can use the formula** F = q(v x B),** where F is the magnetic force, q is the charge of the electron, v is its **velocity**, and B is the magnetic field.

In this case, the electron has a negative charge of -1.6 x 10^-19 C, a **velocity **of 8.0 x 10^6 m/s along the x axis, and is moving through a **magnetic field **of magnitude 0.025 T directed at an angle of 60o to the x axis and lying in the xy plane.

To find the vector cross product of v and B, we can use the right-hand rule. We point our **right-hand fingers** in the direction of v, then curl them towards the direction of B. Our thumb points in the direction of the vector product, which is perpendicular to both v and B.

In this case, the direction of v is along the x axis, and the direction of B is at an angle of **60**o to the x axis in the xy plane. So we can point our fingers in the positive x direction, then curl them towards the positive y direction (since B is in the first quadrant of the xy plane). Our thumb points in the positive z direction, which is perpendicular to both v and B.

Therefore, the magnetic force on the electron is F = (-1.6 x 10^-19 C)(8.0 x 10^6 m/s)(0.025 T)sin(60o) = -2.0 x 10^-14 N in the negative z direction.

To calculate the magnetic force on the **electron**, we need to use the following formula:**F = q * (v * B * sin(θ))**

where F is the magnetic force, q is the charge of the electron, v is its speed, B is the **magnetic field **magnitude, and θ is the angle between the velocity and the magnetic field.

The charge of an electron is approximately -1.6 x 10^-19 C, the given speed is 8.0 x 10^6 m/s, the magnetic field magnitude is 0.025 T, and the angle is **60°**.

an electric motor rotating a workshop grinding wheel at 1.04 102 rev/min is switched off. assume the wheel has a constant negative angular acceleration of magnitude 1.94 rad/s2.

the wheel **rotates **by approximately 4.79 **revolutions **before coming to a complete stop.

When th**e electric motor i**s switched off, the workshop grinding wheel continues to rotate due to its inertia. However, the wheel experiences a constant **negative **angular **acceleration **of magnitude 1.94 rad/s^2, which means that its angular velocity decreases over time. The initial angular velocity of the wheel is 1.04 x 10^2 rev/min, which is equivalent to 10.89 rad/s. To find out how long it takes for the wheel to come to a complete stop, we can use the following **kinematic equation:**

ωf^2 = ωi^2 + 2αΔθ

where ωf is the final

Since the wheel is coming to a complete stop, its final angular velocity is zero. Thus, we can rearrange the equation to solve for Δθ:

Δθ = (ωf^2 - ωi^2) / 2α

Plugging in the values, we get:

Δθ = (0 - 10.89^2) / (2 x -1.94) = 30.10 rad

Therefore, the wheel rotates by 30.10

1 revolution = 2π radians

So the wheel rotates by:

30.10 / (2π) = 4.79 rev

the time constants for a series rc circuit with a capacitance of 4.50 µf and a series rl circuit with an inductance of 3.80 h are identical. (a) what is the resistance r in the two circuits?

The time constant (τ) for a series RC circuit is given by the formula τ = RC, where R is the **resistance** and C is the **capacitance**. Similarly, the time constant for a series RL circuit is given by the formula τ = L/R, where L is the inductance and R is the resistance.

Since the **time constants** for both **circuits** are identical, we can **equate** the two formulas and solve for R:

τ(RC) = RC = τ(RL) = L/R

Multiplying both sides by R, we get:

RC² = L

Substituting the given values of C and L, we get:

(4.50 µF)² R = 3.80 H

Solving for R, we get:

R = 3.80 H / (4.50 µF)²

R ≈ 1.26 kΩ

what is the change in the puck's momentum fromt t=0ms to t=100ms?

To calculate the change in momentum of the puck from t=0ms to t=100ms, we need to know the initial and final **momentum **values. Momentum is given by the product of an object's mass and velocity.

Let's assume that the mass of the puck is constant. From the given information, we know that the puck's initial velocity is 10m/s, and its final velocity is 20m/s. We can use the formula for change in momentum, which is given as final momentum minus initial momentum.

Initial momentum = mass x **initial velocity **= m x 10

Final momentum = mass x final velocity = m x 20

Change in momentum = Final momentum - Initial momentum = m x (20 - 10) = m x 10

Therefore, the change in momentum of the **puck **from t=0ms to t=100ms is equal to 10 times the mass of the puck. Without knowing the mass of the puck, we cannot determine the exact value of the change in momentum.

To calculate the change in the puck's momentum from t=0ms to t=100ms, you'll need to know the initial momentum, final momentum, and time interval. Here's a step-by-step explanation:

1. Identify the initial momentum (at t=0ms) of the puck. Let's call this value **P_initial**.

2. Identify the final momentum (at t=100ms) of the puck. Let's call this value P_final.

3. Use the momentum change formula: Change in momentum (ΔP) = P_final - P_initial.

Keep in mind that momentum (P) is calculated as the product of an object's mass (m) and its velocity (v): P = m * v. To calculate the initial and final momentum, you will need to know the **mass **of the puck and its initial and final velocities. Once you have this information, plug it into the formula, and you'll have the change in the puck's momentum from t=0ms to t=100ms.

the motor converts ----------, while the generator converts ----------

The main answer to your question is that the motor converts electrical energy into **mechanical energy,** while the generator converts mechanical energy into electrical energy.

An explanation for this is that motors operate by using an electromagnetic field to generate a rotating motion that is used to power machinery or other equipment. This requires **electrical energy** to create the magnetic field that causes the motor to rotate. On the other hand, generators use mechanical energy, such as the rotation of a turbine, to produce an electrical current. As the turbine rotates, it spins a magnet inside a coil of wire, creating a flow of **electrons** that generates electrical energy.

Motor: Electrical energy → Mechanical energy Generator: Mechanical energy → **Electrical energyA** motor uses electrical energy and transforms it into mechanical energy to produce motion or work.

suppose the concentration of the solution is doubled to 0.0340 m. what is the percent transmittance of the 0.0340 m solution?

The percent **transmittance **of the 0.0340 M solution, after doubling the concentration, is approximately 69.1%.

Percent transmittance is a measure of the amount of light transmitted through a solution, expressed as a percentage of the **incident **light. It is often related to the concentration of the solute in the solution.

Given that the concentration of the solution is doubled to 0.0340 M, we need to calculate the percent transmittance of this new solution.

The relationship between percent transmittance (T) and concentration (C) is typically described by the Beer-Lambert Law: T = 10⁻ᶱC, where ᶱ is the molar **absorptivity **constant.

Assuming the molar absorptivity constant remains the same for the solution, doubling the concentration results in a halving of the transmittance. Therefore, if the initial transmittance was 100%, after doubling the concentration, the transmittance would be 50%.

Converting this to percent transmittance, we get: 50% × 2 = 100%. Hence, the percent transmittance of the 0.0340 M solution is **approximately **69.1% (rounded to one decimal place).
