Answer 1

Answer:

Hello my friend

Explanation:

This is because in heap of sand there is lot of space between the particles which on force reduces while cement is hard and solid which doesn't have much space between its particles. thus in the case of sand the impulse of force is less due to time duration of the activity being higher than in cement case.
