Question

pressure is the force being exerted per unit of surface area. we can calculate pressure using the following formula: p = f / a p is the symbol representing pressure and this is expressed in pascals (pa). f is the symbol representing force and force is expressed in newtons (n). a is the symbol representing surface area and this is expressed in meters squared (m²). a block with a surface area of 4 m² is pressed against the ground using a force of 100 n. calculate the pressure. pa

Explanation:

Step1: Identify given values

We know that the force \( F = 100\space N \) and the surface area \( A = 4\space m^2 \). The formula for pressure is \( p=\frac{F}{A} \).

Step2: Substitute values into formula

Substitute \( F = 100\space N \) and \( A = 4\space m^2 \) into the formula \( p=\frac{F}{A} \). So we have \( p=\frac{100}{4} \).

Step3: Calculate the result

Calculate \( \frac{100}{4}=25 \).

Answer:

25
