The atmospheric pressure above a swimming pool changes from 837 to 842 mm of mercury. The bottom of the pool is a rectangle (10 m ⨯ 25 m). By how much does the force on the bottom of the pool increase?

Respuesta :

Answer:

Change in force = 1.66 × 10⁵ N

Explanation:

Given:

Initial pressure = 837 mmHg

Final pressure = 842 mmHg

Rectangle (10 m ⨯ 25 m)

Find:

Change in force

Computation:

Change in force = (Change in pressure)(Area)(133 pa / 1 mmHg)

Change in force = (842 - 837)(10 m ⨯ 25 m)(133 pa / 1 mmHg)

Change in force = (166,250)

Change in force = 1.66 × 10⁵ N
