Answers

Complete question:

An electron is released in a uniform electric field with a magnitude of 8000 V/m. The electron is displaced 2 m as a result. Find the potential difference between the electron's initial and final position.

Answer:

the potential difference between the electron's initial and final position is 16,000 V.

Explanation:

Given;

magnitude of the electric field, E = 8,000 V/m

initial position of the electron, x₀ = 0

final position of the electron, x₁ = 2 m

The potential difference between the electron's initial and final position;

V = E(x₁ - x₀)

V = 8000(2 - 0)

V = 16,000 V

Therefore, the potential difference between the electron's initial and final position is 16,000 V.

Uniformly charged ring with 180 nC/m and radius R= 58 cm. Find the magnitude of the electric field in KN/C at a point P on the axis of the ring at distance 116 cm from its center.

Answers

Answer:

3.135 kN/C

Explanation:

The electric field on the axis of a charged ring with radius R and distance z from the axis is E = qz/{4πε₀[√(z² + R²)]³}

Given that R = 58 cm = 0.58 m, z = 116 cm = 1.16m, q = total charge on ring = λl where λ = charge density on ring = 180 nC/m = 180 × 10⁻⁹ C/m and l = length of ring = 2πR. So q = λl = λ2πR = 180 × 10⁻⁹ C/m × 2π(0.58 m) = 208.8π × 10⁻⁹ C and ε₀ = permittivity of free space = 8.854 × 10⁻¹² F/m

So, E = qz/{4πε₀[√(z² + R²)]³}

E = 208.8π × 10⁻⁹ C × 1.16 m/{4π8.854 × 10⁻¹² F/m[√((1.16 m)² + (0.58 m)²)]³}

E = 242.208 × 10⁻⁹ Cm/{35.416 × 10⁻¹² F/m[√(1.3456 m² + 0.3364 m²)]³}

E = 242.208 × 10⁻⁹ Cm/35.416 × 10⁻¹² F/m[√(1.682 m²)]³}

E = 6.839 × 10³ Cm²/[1.297 m]³F

E = 6.839 × 10³ Cm²/2.182 m³F

E = 3.135 × 10³ V/m

E = 3.135 × 10³ N/C

E = 3.135 kN/C

What amount of energy is needed for an electron to jump from n = 1 to n = 4?

Answers

Answer:

[tex]E=2.04\times 10^{-18}\ J[/tex]

Explanation:

We need to find the energy for an electron to jump from n = 1 to n = 4.

The energy in transition from 1 state to another is given by :

[tex]E=\dfrac{-2.18\times 10^{-18}}{n^2}\ J[/tex]

The difference in energy for n = 1 to n = 4 is:

[tex]E=-2.18\times 10^{-18}\times (\dfrac{1}{4^2}-1)\\\\E=2.04\times 10^{-18}\ J[/tex]

So, the required energy is equal to [tex]2.04\times 10^{-18}\ J[/tex].

a sample contains 110 g of a radioactive isotope. how much radioactive isotope will remain in the sample after 1 half-life?

a. 100g
b. 25 g
c. 75 g
d. 50 g

Answers

Answer:

The half-life of a radioactive isotope is the time such that the initial amount of the isotope is reduced to its half.

Thus, if we start with A grams of a given radioactive isotope, after a 1 half-life, we will have A/2 grams of the radioactive isotope.

In this case, we know that the sample has 110g of a radioactive isotope.

Then, after 1 half-life, we should have half of 110g, which is:

110g/2 = 55g

Then we should have 55 g of a radioactive isotope.

The answer that is closer to this result is option d (50 g), so that is the correct one.

HELP! block is released from rest and slides down a frictionless ramp inclined at 30' from the horizontal. When the block reaches the bottom the block-Earth system has mechanical energy Eo The
experiment is repeated, but now horizontal and vertical forces of magnitude F are exerted on the block while it slides, as shown above. When the block reaches the bottom, the mechanical energy
of the block-Earth system
A) is greater than Eo
B)is equal to Eo
C)is less than Eo
D)cannot be determined without knowing

Answers

Answer:

A

Explanation:

the horizontal and vertical force acting on it consist a net force on the inclined direction (30degrees below the horizontal) you can tell by the length of the horizontal component (try to see the 30degree incline as horizontal, because that's the direction of the displacement). net work done on the system results in an increase in energy. i hope this can help :D, i'm also taking the ap physics 1 exam tommorow.

When the block reaches the bottom, the mechanical energy of the block-Earth system is greater than Eo.

The given parameters:

Inclination of the ramp, θ = 30⁰

The work - done on the block is calculated as follows;

[tex]W = F d \times cos(\theta)[/tex]

where;

d is the displacement of the block

When the block reaches the bottom, the displacement increases.

Based on work-energy theorem, as the work done increases, the mechanical energy increases as well.

Thus, when the block reaches the bottom, the mechanical energy

of the block-Earth system is greater than Eo.

Answer:

True 1, 2,3, 6, 8 and 10

False 4, 5, 7 and 9

Explanation:

In this exercise, several situations will be analyzed, to know if they are true/false

1) True. Bernoulli's equation is the conservation of energy

2) True. The volumetric expansion is approximately 4 times the linear expansion

3) True. Latent heat is the heat used in a phase transformation and does not change the temperature of the body and the conduction is proportional to the change in temperature.

4) False. The particle can be at rest or at constant velocity

5) False. Acceleration depends on the force of the kick

6) True. The sum of force must be zero

7) False. Reflection occurs at the interface between two different media

8) True. Diverging lenses the focal length is negative

9) False. Manganic energy is the sum of the energies, therefore it must be different from zero

10) True. The electric field is inversely propositional to the square of the distance

A car accelerates at a rate of 13m/s^2[S]. If the car's initial velocity is 120km/h[N]. What will its final velocity be in m/s, after two seconds.

Answers

Answer:

the final velocity of the car is 59.33 m/s [N]

Explanation:

Given;

acceleration of the car, a = 13 m/s²

initial velocity of the car, u = 120 km/h = 33.33 m/s

duration of the car motion, t = 2 s

The final velocity of the car in the same direction is calculated as follows;

v = u + at

where;

v is the final velocity of the car

v = 33.33 + (13 x 2)

v = 59.33 m/s [N]

Therefore, the final velocity of the car is 59.33 m/s [N]
