Question

A nail penetrates deeper into the wall when a heavy hammer strikes it

Answer 1

Answer:

i hope the explanation is enough.

Explanation:

According to the formula,

Pressure (P) = Force (F) / Area (A)

If the Area is smaller the Pressure is larger and hence the force will be larger.

Since, the cross sectional area of the nail is very small the force applied by the hammer will be larger and the nail will penetrate deeper into the wall.
