Chapter 14: Q. 7 (page 383)

Blocks a, b, and c in FIGURE Q14.7 have the same volume. Rank in order, from largest to smallest, the sizes of the buoyant forces Fa , Fb , and Fc on a, b, and c. Explain.

Short Answer

Expert verified

Buoyant forces are equal on all three blocks, soFa = Fb = Fc

Step by step solution

01

Given information

The figure given with 3 objects with same volume is submerged in liquid.

02

Explanation

We know that buoyant force acting on a mass floating in a liquid depends on density of object, submerged volume of object and gravity.

F= Vs ρ g ……..................(1)

Where

F = buoyant force

Vs = submerged volume

ρ = density of liquid

g = gravity

As the volume of all objects are same so buoyant force will be same .

So.

Fa = Fb =Fc

Most popular questions from this chapter

A friend asks you how much pressure is in your car tires. You know that the tire manufacturer recommends 30psi, but it's been a while since you've checked. You can't find a tire gauge in the car, but you do find the owner's manual and a ruler. Fortunately, you've just finished taking physics, so you tell your friend, "I don't know, but I can figure it out." From the owner's manual you find that the car's mass is1500kg. It seems reasonable to assume that each tire supports one-fourth of the weight. With the ruler you find that the tires are 15cm wide and the flattened segment of the tire in contact with the road is 13cm long. What answer-in psi-will you give your friend?

A 10-cm-diameter, 20-cm-tallsteel cylinderρsteel=7900kg/m3 floats in mercury. The axis of the cylinder is perpendicular to the surface. What length of steel is above the surface?

The tank shown in FIGURECP14.72is completely filled with a liquid of density ρ. The right face is not permanently attached to the tank but, instead, is held against a rubber seal by the tension in a spring. To prevent leakage, the spring must both pull with sufficient strength and prevent a torque from pushing the bottom of the right face out.

a. What minimum spring tension is needed?

b. If the spring has the minimum tension, at what height dfrom the bottom must it be attached?

A 6.0 m * 12.0 m swimming pool slopes linearly from a 1.0 m depth at one end to a 3.0 m depth at the other. What is the mass of water in the pool?

A 20-cm-diameter circular cover is placed over a 10-cm-diameter hole that leads into an evacuated chamber. The pressure in the chamber is 20 kPa. How much force is required to pull the cover off?
