Q: Repeat Prob. 11–22 for the case of a partially

Repeat Prob. 11–22 for the case of a partially filled trough with a water height of 0.35 m directly above the hinge. Data from Prob. 11-22: The two sides of a V-shaped water trough...

Q: What is the difference between the macroscopic and microscopic forms of energy

What is the difference between the macroscopic and microscopic forms of energy?

Q: A 4-m-long quarter-circular gate of radius

A 4-m-long quarter-circular gate of radius 3 m and of negligible weight is hinged about its upper edge A, as shown in Fig. P11–24. The gate controls the flow of water over the ledge...

Repeat Prob. 11–24 for a radius of 2 m for the gate. Data from Prob. 11-24: A 4-m-long quarter-circular gate of radius 3 m and of negligible weight is hinged about its upper edge A,...

Q: What is buoyant force? What causes it? What is the

What is buoyant force? What causes it? What is the magnitude of the buoyant force acting on a submerged body whose volume is V? What are the direction and the line of action of the buoyant force?

Q: Discuss the stability of (a) a submerged and (b

Discuss the stability of (a) a submerged and (b) a floating body whose center of gravity is above the center of buoyancy.

Q: Consider two 5-cm-diameter spherical balls—one made

Consider two 5-cm-diameter spherical balls—one made of aluminum, the other of iron—submerged in water. Will the buoyant forces acting on these two balls be the same or different? Explain.

Q: Consider a 3-kg copper cube and a 3-kg

Consider a 3-kg copper cube and a 3-kg copper ball submerged in a liquid. Will the buoyant forces acting on these two bodies be the same or different? Explain.

Q: Someone claims that she can determine the magnitude of the hydrostatic force

Someone claims that she can determine the magnitude of the hydrostatic force acting on a plane surface submerged in water regardless of its shape and orientation if she knows the vertical distance of...

Q: Consider two identical spherical balls submerged in water at different depths.

Consider two identical spherical balls submerged in water at different depths. Will the buoyant forces acting on these two balls be the same or different? Explain.
