Howard Rodgers · Answer 1

it was 12 m because 10 m and if you lift it twice i will be 12

Michelle Hubbard · Answer 2

Answer: C: Two times

Explanation:

Increase in height would lead to increase in potential energy by that same amount as long as the mass remains constant

Mass=

g = acceleration due to gravity

h = Height

M*g*10 = M*g * (2*10)

10mg = 20mg

Divide both sides by 10mg

Equals to 2.

Hence, increase in height by 2 times the original height would lead to twice the increase in potential energy
