Answer 1

Answer:

P= F/A

Explanation:

P = 24×1000000/ 30×10×10

P= 8× 10^3 pa

Answer 2

Explanation:

Given,

Length = 30cm = 0.3m

Wide = 10cm=0.1m

Thick = 10cm=0.1m

Force = 24N

To Find:-

pressure exerted by the brick on the ground.

Formula used:-

Pressure = Force / Area

Calculations :-

Pressure = Force / Area

substituting the given values

Here,

we can get two answers:-

Brick is lying with area 30 cm × 10 cm in contact

so,

so pressure will 800pa

Brick is lying with area 10 cm × 10 cm in contact

so,

=2400pa
