Question

4.A pressure of 1000 Pa is required to pierce a wooden block. If a sharp nail of area 0.1 cm is used,calculate the force required to pierce the wood.​

Answer 1

Answer:

use simple formula.

pressure = force/area.

put, the value and get answer.....

Answer 2

Answer:

Apply formula, Pressure=Force/Area

Explanation:

Given P=1000 pa, A=0.1 cm

change Area into metre. (1m =100cm, 1cm=1/100m=00.1m)

so now A= 0.001m

now put the value of A in formula ,P=F/A

Force = 1000pa x0.001m=1N

so 1 N force is required.
