Answer:
D. 100 J
Explanation:
Given
Mass (m) = 2 kg
Height (h) = 5 m
Acceleration due to gravity (g) = 10 m/s²
Now
Work done(W)
= m * g * h
= 2 * 10 * 5
= 100 Joule
Hope it will help :)❤
The ball should take twice as long to return to its original position as it took to reach its maximum height, so it should return to its original position at .
light and radiation is able to experience by an observer watching the explosion from the vacuum.
<u>Explanation:</u>
- Basically in the nuclear explosion, there will be an enormous of energy released as noise, heat, visible light, radiation and atmospheric wave.
- Usually sound and wave propagate through medium but in vacuum, there will be no medium to transfer this type of energy. so there is no chance of sound and wave transfer.
- Light and radiation travel in vacuum because they didn't need the medium to transfer .
Given data :
Work (W) = 1200 J ,
distance (S) = 20 m ,
Determine the Force applied to the box = ?
Work done = F. S
1200 = F . 20
F = 60 N
<em>Force applied to the box is 60 N</em>
