Answer:
EXplained
Explanation:
from conservation of energy
change in potential energy = gain in kinetic energy
so as all he balls are throws from the same height thus the change in potential energy is the same for all the balls thus the gain in kinetic energy is the same for all the balls and as they have the same initial velocity thus the final velocity is the same for all the balls.
The density, hard, strong, and rough.
Answer:
extreme heat, because no physical damage can demagnetize a magnet
Explanation:
People are asleep at 3 am so energy would be less then.
