Read each question carefully and answer to the best of your ability. Show all your work for calculation problems.
1. Which of the following is NOT a characteristic of a fluid?
Takes the shape of its container
Has a definite shape
Can flow
Particles are not rigidly fixed
2. What is the SI unit for pressure?
Newton
Joule
Pascal
Watt
1. The principle that states an object submerged in a fluid experiences an upward buoyant force equal to the weight of the fluid displaced is known as 's Principle.
2. A fluid's resistance to flow is called its .
1. Explain the difference between laminar flow and turbulent flow.
2. State Pascal's Principle and provide a real-world application.
1. The pressure in a fluid increases with depth.
True
False
2. Bernoulli's principle states that as the speed of a fluid increases, its pressure also increases.
True
False
Match the term on the left with its definition on the right.
1. Density
a. The upward force exerted by a fluid that opposes the weight of an immersed object.
2. Buoyancy
b. Mass per unit volume of a substance.
3. Viscosity
c. A fluid's resistance to flow.
1. A submarine dives to a depth of 150 meters in the ocean. If the density of seawater is 1025 kg/m³ and the acceleration due to gravity is 9.8 m/s², calculate the pressure exerted on the submarine at this depth. (Ignore atmospheric pressure)
2. An object with a volume of 0.05 m³ is fully submerged in water (density = 1000 kg/m³). Calculate the buoyant force acting on the object.
