In this worksheet, we will practice using the formula for pressure, p = F/A, to calculate pressures that are produced by forces acting on areas.

**Q2: **

Which of the following formulas correctly shows the relationship between an applied force, the pressure that the force produces, and the area on which the force acts?

- A
- B
- C
- D
- E

**Q3: **

An empty water tank has a rectangular base with side lengths of 1.2 m and 2.3 m. The weight of the tank applies a pressure of 350 Pa to the surface it is resting on. What is the weight of the tank?

**Q4: **

The bases of a manβs feet have a total area in contact with the ground of
0.025 m^{2}. The manβs weight is
800 N. How much is the pressure
applied by his feet to the ground in kilopascals?

**Q5: **

A pressure of 20 Pa is applied by an N force to a square area. What is the length of a side of the square?

**Q6: **

A pressure of 75 Pa is applied by a 3β000 N force. What area is the force applied to?

**Q7: **

A pressure of 400 Pa is applied to an
area of 2.5 m^{2}. What force applies this
pressure?

**Q8: **

2.5 m^{2}. What pressure does
the sofa apply to the ground beneath it?

**Q9: **

A dancer with a mass of 50 kg is standing on the tips of the toes of one of her feet. She exerts a pressure of 490 kPa on the tips. What is the area, in square centimeters, of the part of the foot on which she stands?
