Question

4 The surface area of the end of a brick
is 50cm². The surface area of the base
of another brick. is 200cm3. Each brick
Weighe 50N.What fressure each of the brick

Answer 1

Answer:

Explanation:

Pressure = Thrust/Area

Thrust = Weight = 100 N

Area of the brick in contact with the ground = 10 cm x 5 cm

= 50 x 10−4 m2

Pressure exerted by the brick on the ground = 100 N/(50 x 10−4 m2) = 1.6 x 104 N/m2

= 1.6 x 104 Pa.
