Answer:
A car traveling on a highway takes to stop without skidding. What happens to its kinetic energy? ... The energy goes to parts of the brakes. No, the energy can only be reused if there is a heat pump present
The electrical energy consumed in one year by using the light bulbs is 8,760 kWh.
The given parameters:
- Number of light bulbs = 10
- Power consumed by each bulb = 100 W
- Time of energy consumption, t = 1 year
<h3>What is electrical energy?</h3>
This is the electric power consumed or dissipated at a given period of time.
The electrical energy consumed in one year by using the light bulbs is calculated as
E = Pt
Thus, the electrical energy consumed in one year by using the light bulbs is 8,760 kWh.

1. Answer:
The relationship between Force A and Force B is given as:
A = B
Explanation:
To produce acceleration to a body, an unbalanced force must be applied. Meaning that a Force must be applied to the body greater than that of Force of Friction.
In our case, a Force A is exerted on the crate which is moving with a constant velocity. As there is no acceleration, the force applied must be equal to the force of Friction B.
2. Answer:
The electron's acceleration is 1.756 x 10¹⁷ ms⁻².
Explanation:
Electric field exerts a Force on the electron given as:
F = 1.6 x 10⁻¹³ N
Rest mass of electron = 9.11 x 10⁻³¹ kg
According to newton's 2nd law of motion, a net force F applied on the electron must produce an acceleration 'a' which is directly proportional to the Force and inversely proportional to the rest mass of the electron given as:
a = F/m
a = (1.6 x 10⁻¹³)/(9.11 x 10⁻³¹)
a = 1.756 x 10¹⁷ ms⁻²
