Question

Calculate the Force if the pressure is equal to 9.9 × 10^5 Pa, and the area is equal to 9.9 mm^2.

a) 9.9 N
b) 99 N
c) 0.99 N
d) 999 N

Answer 1

The force can be calculated using the formula F = P × A, where F is the force, P is the pressure, and A is the area. Plugging in the given values, we get a force of 9.9 N.

Step-by-step explanation:

To calculate the force, we can use the formula:
F = P × A
where F is the force, P is the pressure, and A is the area. In this case, the pressure is given as 9.9 × 105 Pa and the area is 9.9 mm2. We need to convert the area to square meters, as the formula requires SI units. Since 1 mm2 is equal to 10-6 m2, the area can be written as 9.9 × 10-6 m2. Plugging in the values, we get:
F = 9.9 × 105 Pa × 9.9 × 10-6 m2
Simplifying the expression, we get:
F = 9.9 N
