Question

2.
a. A force of 100 N is applied on an area of 4 m². Compute pressure being applied on the area. Use proper unit in your calculation.

b. Refer to the fig. and answer the question. Which shoe would you advise Archana to wear when she is planning to go on a beach? Give reasons for your advice.​

Answer 1

Answer:

a. $25 N/m^{2}$ or 25 Pa

b. Flat Shoe

Explanation:

a. Pressure = Thrust/Area

Pressure = (100/4) $N/m^{2}$

               = 25 $N/m^{2}$ or 25 Pa

$N/m^{2}$ is also known as pascal, so we can write it as 25 Pa.

b. It is advisable to use flat shoe since it has more area of contact with the sand on beach, when we stand on it. This would prevent the shoe from sinking in the sand, and we can walk freely.
