Question

Calculate the pressure in Pascal exerted by a force of 300 Newton acting normally on a area of 30 cm square

Answer 1

pressure=force/area
force=300N
area=30sqcm
then pressure= 300/30=10
in Pascal 1pascal =
$1 \times {10}^{ - 5}$
so answer is
$10 \times {10 }^{ - 5}$

Answer 2

Answer:

given

force = 30 n

distance = 5m

work done = f × d

(30 × 5 × cos0⁰)
