Ответ:
It’s a force that slowly wears away mountains and other features on earths surface, such as erosion.
Ответ:
2.It has twice the KE
Explanation:
Given that
m ₁ = 2 m₂
Height = h
For mass m ₁ :
By using energy conservation
m ₁ g h = KE₁
KE₁ = m ₁ g h
For mass m ₂ :
By using energy conservation
m ₂g h = KE₂
KE₂= m ₂ g h
m ₁ = 2 m₂
KE₁ = m ₁ g h
KE₁ =2 m₂ g h
KE₁ = 2 KE₂
The kinetic energy for the massive marble is twice the other one marble.
Therefore the answer will be 2.
