• force and time

• electric charge and time

• none of these

An egg gets dropped from a height of 0.1 meters and cracks. A second egg gets dropped from the same height but this time it lands on a glass of water and does not break. In terms of impulse.

• 1st egg experienced more impulse

• 2nd egg experienced more impulse

• both experienced the same impulse
