Question

1.       The surface area of the end of a brick is 50cm2. The surface area of the base of another brick is 200cm2. Each brick weighs 50N. What pressure each of the brick exerts on the ground?​

Answer 1

Answer:

1st brick - 10,000 Pa and 2nd brick- 2500 Pa

Explanation:

Pressure - Force/Area

Pressure of 1st brick - 50N/50cm2 = 50N/0.005m2 = 10,000 Pa

Pressure of 2nd brick - 50N/200cm2 = 50N/0.02m2 = 2500 Pa
