If a 2kg ball rolls at a speed of 10 m/s on the ground, this is an example of kinetic energy. When a mass of the body moves at a specific rate, there is movement. The equation for kinetic energy is 1/2mv^2. Therefore the kinetic energy of the ball is (1/2)(2kg)(10m/s)^2 is 100 Joules.

Answer:

A) Emin = eV

B) Vo = (E_light - Φ) ÷ e

Explanation:

A)

Energy of electron is the product of electron charge and the applied potential difference.

The energy of an electron in this electric field with potential difference V will be eV. Since this is the least energy that the electron must reach to break out, then the minimum energy required by this electron will be;

Emin = eV

B)

The maximum stopping potential energy is eVo,

The energy of the electron due to the light is E_light.

If the minimum energy electron must posses is Φ, then the minimum energy electron must have to reach the detectors will be equal to the energy of the light minus the maximum stopping potential energy

Φ = E_light - eVo

Therefore,

eVo = E_light - Φ

Vo = (E_light - Φ) ÷ e
