1. Calculate the equivalent resistance in the circuit :

In the given diagram, the resistors are in series connection,

So equivalent resistance = sum of resistance of both resistors.

[tex] \large \boxed{R_{eq} =R_1 +R_2 }[/tex]

Therefore, Equivalent resistance = 840 ohms.

2. Calculate the current through the battery :

[tex] \boxed{ \mathrm{current = \dfrac{potential \: \: difference}{resistance} }}[/tex]

Hence, current through the battery = 0.142 A

3. How much current is passing through each resistor :

Since the resistors are joined in series connection, the current flowing through each resistor will be equal = 0.142 Amperes.

Answer:

The effective spring constant of the firing mechanism is approximately 21.804 N/m

Explanation:

The mass of the circus performer, m = 75.6 kg

The angle of elevation above the horizontal, θ = 37.2°

The instrument the cannon uses to propel the performer = Strong elastic band

The length by which the band stretches, x = 2.70 m

The height of the performer above the floor at the point the performer flies free of the bands = The height of the net into which he is shot

The time he takes to travel the horizontal distance between the point he is shot and the net, t = 2.34 s

The horizontal distance between the the point he is shot and the net, dₓ = 26.9 m

Therefore, the horizontal component of the velocity, vₓ, can be found with the following kinematic equation of motion;

vₓ = dₓ/t

∴ vₓ = 2.70 m/(2.34 s) = (15/13) m/s

By the resolution of the initial velocity, 'v', into the horizontal and vertical component, we have;

The horizontal component, vₓ = v × cos(θ)

∴ v = vₓ/(cos(θ))

v = (15/13)/(cos(37.2°)) ≈ 1.45

The initial velocity, v ≈ 1.45 m/s

The kinetic energy given to the circus performer by the elastic band, K.E., is given as follows;

K.E. = (1/2)·m·v²

Where;

m = The mass of the performer = 75.6 kg

v = The velocity given to the performer ≈ 1.45 m/s

∴ K.E. ≈ (1/2) × 75.6 × 1.45² ≈ 79.475

∴ K.E. ≈ 79.475 J

The kinetic energy, K.E., given to the performer, (1/2)×m×v² = The kinetic energy of the elastic band = (1/2)×k×x²

Where;

k = The effective spring constant of the firing mechanism

x = The extension of the sling = 2.70 m

Therefore, we get;

K.E. = (1/2)·m·v² = (1/2)·k·x²

∴ K.E. ≈ 79.475 J = (1/2) × 75.6 × 1.45² = (1/2) × k × (2.70 m)²

∴ 79.475 J ≈ (1/2) × k × (2.70 m)²

k = 79.475 J/((1/2) × (2.70 m)²) ≈ 21.804 N/m

The effective spring constant of the firing mechanism, k ≈ 21.804 N/m.

Explanation:

H2O2 H2O

H2 + O2 → H2O. Word equation: Hydrogen gas + Oxygen gas → water. Type of Chemical Reaction: For this reaction we have a Combination reaction. Balancing Strategies: For this reaction it is helpful to start by changing the coefficient in front of H2O and so that you have an even number of oxygen atoms.

Answer: Mass is the quantity of matter in an object whereas weight is the force of gravity on an object.

Answer:

f = 12 cm

Explanation:

Center of Curvature:

The center of that hollow sphere, whose part is the spherical mirror, is known as the ‘Center of Curvature’ of  mirror.

The Radius of Curvature:

The radius of that hollow sphere, whose part is the spherical mirror, is known as the ‘Radius of Curvature’ of  mirror. It is the distance from pole to the center of curvature.

Focal Length:

The distance between principal focus and pole is called ‘Focal Length’. It is denoted by ‘F’.

The focal length of the spherical (concave) mirror is approximately equal to half of the radius of curvature:

[tex]f = \frac{R}{2}[/tex]

where,

f = focal length = ?

R = Radius of curvature = 24 cm

Therefore,

[tex]f = \frac{24\ cm}{2}[/tex]

f = 12 cm

Answer:

I would like to attach options to the question above for clarity.

Jasmine is investigating the effect force has on the motion of an object. She predicts if she puts a strong force on pushing a bowling ball, it will travel a farther distance than when a weak force is applied. Is her prediction correct?

A. No, a weak or a strong force applied to the ball is unable to affect the motion of the ball.

B. No, the force applied to the bowling ball should be a strong force.

C. Yes, the force applied to the bowling ball affects the motion of the ball.

D. Yes, the ball will travel a longer distance when a weak force is applied.

The correct option is C (Yes, the force applied to the bowling ball affects the motion of the ball).

Explanation:

First, a force is any effort either push or pull that causes an object to undergo a change.

A bowling ball can remain at rest or in motion except a force acts on it. This brings us to the question above, the mass which affects force is not mentioned which means it is uniform or negligible. Recall that force = mass X acceleration. So the greater the force that is applied to the bowling ball the further distance it will travel. From the question, she applied a forward force (pushing), so the more force she applies the further the bowling ball will travel.

Answer:

Weight = 966 Newton.

Explanation:

Given the following data;

Length = 1.2 m

Width = 2.3 m

Pressure = 350 Pa

To find the weight of the tank;

We know that weight is the force of gravity acting on an object multiplied by its mass.

Weight = mg = force

Hence, we would determine the force using the parameters that were given.

But we would first determine the area of the rectangular tank.

Area of rectangle, A = length * width

A = 1.2 * 2.3

A = 2.76 m²

Mathematically, pressure is given by the formula;

Pressure = force/area

Force = pressure * area

Substituting into the formula, we have;

Force = 2.76 * 350

Force = 966 Newton

Therefore, the weight of the tank is 966 Newton.

Answer:

D

Explanation:

ionic compounds conduct electricity when molten or dissolved in water. ionic compounds conduct electricity when dissolved in water because water molecules are attracted to ions, this weakens the strong electrostatic forces of attraction between the oppositely charged ions. thus, ions are pulled away from the lattice structure and the remaining compound dissolves in water to form aqueous solution. The presence of free moving ions enables the ionic compound to conduct electricity.

Answer:

[tex]E=8.13\times 10^{12}\ J[/tex]

Explanation:

Given that,

The mass of a Hubble Space Telescope, [tex]m_1=1.16\times 10^4\ kg[/tex]

It orbits the Earth at an altitude of [tex]5.68\times 10^5\ m[/tex]

We need to find the potential energy the telescope at this location. The formula for potential energy is given by :

[tex]E=\dfrac{Gm_1m_e}{r}[/tex]

Where

[tex]m_e[/tex] is the mass of Earth

Put all the values,

[tex]E=\dfrac{6.67\times 10^{-11}\times 1.16\times 10^4\times 5.97\times 10^{24}}{5.68\times 10^5}\\\\E=8.13\times 10^{12}\ J[/tex]

So, the potential energy of the telescope is [tex]8.13\times 10^{12}\ J[/tex].
