What if I don’t give you the answer
I would guess it's light, electricity, and magnetism.
Hope I could help!
Answer:
7.65 X 10^12 m/s
Explanation:
When the debris falls, at that instance P.E = K.E
mgh=mv^2/ 2
mass of the earth= 5.972 × 10^24
height=5.972 × 10^24/2
Height h= 2.986 × 10^24
V=√(2gh)
V= √(2 * 9.8 * 2.986 *10^24)
V= 7.65 X 10^12 m/s
