Question

1.Why it is easier to walk on soft sand if we have flat shoes rather than shoes with sharp heels (or pencil heels)? 2.We know that there is a huge amount of atmospheric pressure on us. But we do not experience its effect why? 3.It is difficult to cut cloth using a pair of scissors with blunt blades. Explain.

Answer 1

with blunt blades the force cannot be exerted the way we want it
