Question

a force of 12 n is uniformly distributed over an area of 120 cm.find the pressure in pascals.

Answer 1

Pressure =Force/Area =12N/ 120 sq.cm.=12/120×10^-4 N/m =1000N/m =1000 Pascals.
1m=100cm and 1sq.m.=100cm×100cm=10^4 sq.cm. So l sq.cm=10^-4 sq.m.Hope it helps you...

Answer 2

Answer:

Explanation:Pressure = force /area

=12N/120sq.cm

=12/120×10^-4N/M

=1000N/M=1000Pascals.

1m= cm and

1sqm =1000cm×100cm=10^-4sq.cm
