Question

1. a girl standing on one foot exerts a pressure of 6500n/m² on the ground. if the area of her foot is 0.008m². calculate the total downward force.

Explanation:

Step1: Recall pressure - force - area formula

The formula for pressure is $P=\frac{F}{A}$, where $P$ is pressure, $F$ is force and $A$ is area. We need to find $F$, and we can re - arrange the formula to $F = P\times A$.

Step2: Substitute given values

Given $P = 6500N/m^{2}$ and $A=0.008m^{2}$. Then $F=6500\times0.008$.

Step3: Calculate the force

$F = 52N$.

Answer:

$52N$
