In an electrical circuit, a capacitor is a component that is used to hold charges.

A capacitor operates under the principle that when an earthed conductor is moved close to a conductor, its capacitance increases noticeably. As a result, a capacitor contains two plates with equal and opposing charges that are spaced apart.

Two metal plates, a substance known as a dielectric, and other components make up a capacitor.

The dielectric is positioned between the parallel metal plates, which are positioned very near to one another, to prevent them from touching.

(a) The speed  of puck A before the collision is determined as 0.847 m/s.

(b) The change in the total kinetic energy of the system that occurs during the collision is 0.009 J.

The speed of puck A before the collision is calculated from the principle of conservation of linear momentum as follows;

m₁u₁ + m₂u₂ = m₁v₁ + m₂v₂

0.251u₁ + 0.371(0) = 0.251( -0.12) + 0.371(0.654)

0.251u₁ = 0.2125

u₁ = 0.2125/0.251

u₁ = 0.847 m/s to the right

Initial kinetic energy = ¹/₂ x 0.251 x (0.847)² + ¹/₂ x 0.371 x (0) = 0.09 J

Final kinetic energy = ¹/₂ x 0.251 x (-0.12)² + ¹/₂ x 0.371 x (0.654)² = 0.081 J

Explanation:

The magnetic force per unit length of the wire is (C) (0.49i - 0.51j - 1.37k) N/m.

To calculate the magnetic force per unit length of the wire, we can use the formula:

F = I * (L x B),

where F is the force, I is the current, L is the length vector of the wire, and B is the magnetic field.

Given:

Current, I = 3A

Length vector, L = √√3 * (i + j + k)

Magnetic field, B = 0.75i + 0.4k

Let's calculate the cross product of L and B:

L x B = | i j k |

|√√3 √√3 √√3|

|0.75 0 0.4|

To evaluate this cross product, we calculate the determinants:

(i) component: (√√3 * 0 - √√3 * 0.4) = -0.4√√3

(j) component: (-√√3 * 0.75 - √√3 * 0) = -0.75√√3

(k) component: (√√3 * 0.75 - √√3 * 0) = 0.75√√3

Now, multiply the cross product by the current:

F = 3A * (-0.4√√3i - 0.75√√3j + 0.75√√3k)

Simplifying this expression gives:

F = (-1.2√√3i - 2.25√√3j + 2.25√√3k) N

Therefore, the magnetic force per unit length of the wire is approximately (-1.2√√3i - 2.25√√3j + 2.25√√3k) N/m.

Comparing the given answer options, the closest match is C. (0.49i - 0.51j - 1.37k) N/m.

Explanation:

We'll begin by calculating the momentum of the Porsche. This can be obtained as follow:

Mass (m) of Porsche = 1361 kg

Velocity (v) of Porsche = 26.82 m/s

Momentum of Porsche =?

Momentum = mass × velocity

Momentum = 1361 × 26.82

Momentum of Porsche = 36502.02 Kgm/s

Finally, we shall determine the velocity you need to be running with in order to have the same momentum as the Porsche. This can be obtained as follow:

Your Mass = 68.03 kg

Your Momentum = Momentum of Porsche = 36502.02 Kgm/s

Your velocity =?

Momentum = mass × velocity

36502.02 = 68.03 × velocity

Divide both side by 68.03

Velocity = 36502.02 / 68.03

Velocity = 536.56 m/s

3.25 [atm.]

Explanation:

1) pV=const, where p - pressure, V - volume.

2) According to this formula: 1*130=40*p=const, then p=130/40=3.25 [atm.]

PS. if it is possible check the suggested solution in other sources.

The pressure - volume relation can be determined using Boyle's law. The pressure of the air after the decrease of volume will be 3.25 atm.

According Boyle's law, at constant temperature, the volume of  a gas is inversely proportional to the pressure of the gas.

Thus, PV = a constant.

Let P1 and V1 be the initial pressure and volume of the gas and P2 and V2 be the final pressure and volume. Then,

P 1 V1 = P2 V2.

Given that, V1 = 130 cm³

P1 = 1  atm

V2 = 40  cm³.

then P2 = P 1V1/V2

              = 130  cm³× 1 atm / 40  cm³

              = 3.25 atm.

Therefore, the pressure inside the pump will be 3.25 atm.

c. mass is 24,490 kg, and

d. pressure is 23,530 Pa.

a) The volume of paraffin in the rectangular storage tank can be calculated using the formula:

Volume = Length x Width x Depth

Given:

Length = 4 m

Width = 3 m

Depth = 2 m

Substituting the values into the formula, we have:

Volume = 4 m x 3 m x 2 m

Volume = 24 m³

Therefore, the volume of paraffin in the tank is 24 cubic meters.

b) The weight of the paraffin can be calculated using the formula:

Weight = Volume x Density x Acceleration due to gravity

The density of paraffin varies, but we can assume a typical value of 10,000 kg/m³. The acceleration due to gravity is approximately 9.8 m/s². Substituting these values into the formula:

Weight = 24 m³ x 10,000 kg/m³ x 9.8 m/s²

Weight = 240,000 N

Therefore, the weight of the paraffin in the tank is 240,000 Newtons.

c) The mass of the paraffin can be calculated using the formula:

Mass = Density x Volume

Substituting the given values:

Mass = 10,000 kg/m³ x 24 m³

U = 76.8 μJ

Part E

A capacitor consists of pairs of conductors separated by insulators. Capacitors are used to store electric charge.

The specified parameters are;

The voltage across ab = 48 V

The capacitance of the first capacitor, C₁ = 150 nF

Capacitance of the second capacitor, C₂ = 120 nF

Part A

The total charge in a capacitor network can be found as follows;

\(C_{eq} = \left(\dfrac{1}{150} + \dfrac{1}{120} \right)^{-1} nF = \left(\dfrac{3}{200} \right)^{-1}nF\)

\(C_{eq} =\left(\dfrac{3}{200} \right)^{-1}nF=66\frac{2}{3} \, nF\)

\(Q_{eq} = C_{eq}\times V_{ab}\)

Therefore;

\(Q_{eq}\) = 66 2/3 nF × 48 V = 3,200 × 10⁻⁹ C = 3.2 μC

Part B

The charge in the 150 nF capacitor is obtained from the formula for the charge in a capacitor; Q = C × V as follows;

Q = C₁V₁ = C₂V₂

The charge in the capacitors, C₁ and C₂ are the same as the total charge of 3.2 μC

The charge, Q₁ on the 150 nF capacitor, C₁ is therefore, 3.2 nC

Part C

The capacitors, C₁ and C₂ are in series, therefore, the charge in each capacitor is equivalent to the charge in the circuit, which is 3.2 μC.

Therefore, the charge, Q₂, in the 120 nF capacitor, C₂ is 3.2 μC

Q₂ = 3.2 μF

Part D

The total energy stored in the network can be obtained using the formula;

U = (1/2)·C·V²

Where;

U = The energy in the capacitor

C = The equivalent capacitance of the network = 66 2/3 nF

V = The voltage

Therefore;

\(U = \dfrac{1}{2} \times C_{eq}\times V^2\)

\(U = \dfrac{1}{2} \times 66\frac{2}{3} \times 10^{-9}\times 48^2 = 76.8\)

Part E

The energy stored in the 150 nF capacitor is found as follows;

\(Q_{eq}\) = Q₁ = C₁ × V₁

V₁ = \(Q_{eq}\) ÷ C₁

Therefore;

V₁ = 3.2 μC ÷ 150 nF = \(21\frac{1}{3}\) V

U₁ = 0.5×C₁×V₁²

Part F

The energy stored in the 120 nF capacitor, U₂, can be found as follows;

V₂ = 3.2 μC ÷ 120 nF = \(26\frac{2}{3}\) V

U₂ = 0.5 × 150 nF × \(\left(26\frac{2}{3} \, V\right)^2\) = \(53\frac{1}{3}\, \mathrm{ \mu J}\)

Part G;

The potential difference across the 150 nF, obtained in Part E, is 21 1/3 V

Part H

The potential difference across the 120 nF, obtained in part F, is 26 2/3 V

According to Coulomb’s law, the force of repulsion or attraction between two charged bodies is the multiplication of their charges and is inversely proportional to the square of the distance between them.

The magnitude of the electric force can be written as follows:

\(F =k \frac{q_1q_2}{r^2}\)

where k has a value of 9 × 10⁹ N.m²/C².

Given, the first charge, q₁ = + 80 ×10⁻⁶ C

The second charge , q₂ = - 50 × 10⁻⁶ C

The third charge, q₃ = + 4 ×10⁻⁶ C

The distance between these two charges (q₁ and q₃) , r = 0.30 m

The distance between these two charges (q₂ and q₃) , r = 0.20m

The magnitude of the electrostatic force on the third charges will be:

\(F =9\times 10^9 (\frac{80\times 10^{-6}C\times 4 \times 10^{-6}C}{(0.30)^2} ) +9\times 10^9 (\frac{50\times 10^{-6}C\times 4 \times 10^{-6}C}{(0.20)^2} )\)
