Question 1
What is the formula for calculating pressure at a certain depth in fluid?
- P = Pa + ρgh
- P = ρg/h
- P = ρh/g
💡 Hint: Look for a formula that combines atmospheric pressure and hydrostatic pressure.
Question 2
True or False: Pressure is greater at the bottom of a lake than at the surface.
- True
- False
💡 Hint: Consider the concept of weight and how it affects pressure.
