Answer: time t = 2 seconds
Explanation:
Given that
Power P = 50W
Energy E = 100J
How long did it take to move the box from the floor to the shelf ? This implies time taken.
Power is defined as the rate at which work is done. I.e
P = W.D/t
Where work done = energy
50 = 100/t
Make t the subject of formula
t = 100/50
t = 2 second

nuclear energy
Explanation:
The sunlight that reaches earth is generated by a transformation of nuclear energy. Radiant energy is a from of energy that reaches the earth from nuclear reactions in the core of the sun.
- In this process, light nuclei combines to form larger ones through the process of nuclear fusion.
- This process does not conserve energy and mass is converted to energy.
- The nuclear reaction produces huge energy that goes into the solar system space and lights it up.
- Therefore, it is a transformation of nuclear energy into radiant energy.
- The radiant energy is made up of electromagnetic radiations.
