Read each question carefully and provide your best answer. Show all your work for calculations.
1. Which of the following statements best defines a fluid?
A substance that has a definite shape and volume.
A substance that has a definite volume but no definite shape.
A substance that takes the shape of its container and has no definite volume.
A substance that flows and conforms to the shape of its container.
2. According to Pascal's Principle, a pressure change at any point in a confined incompressible fluid is transmitted:
Undiminished to every portion of the fluid and to the walls of the container.
Only to the top surface of the fluid.
Only to the bottom surface of the fluid.
Only in the direction of the applied force.
1. Viscosity is a measure of a fluid's resistance to flow.
True
False
2. An object will float in a fluid if its density is greater than the fluid's density.
True
False
1. The upward force exerted by a fluid on a submerged object is called .
2. Bernoulli's principle states that as the speed of a fluid increases, its pressure .
1. Explain the difference between laminar flow and turbulent flow in fluids.
2. A hydraulic lift has a small piston with an area of 0.01 m² and a large piston with an area of 0.5 m². If a force of 200 N is applied to the small piston, what is the maximum load that can be lifted by the large piston? (Show your work)
3. The image below shows an Archimedes screw, an ancient device for lifting water. Explain how the principle of buoyancy is related to an object seeming lighter in water, even if the Archimedes screw itself doesn't directly use buoyancy for its operation.
