Chapter 1: Q1 DQ (page 389)

A cube of oak wood with very smooth faces normally floats in water. Suppose you submerge it completely and press one face flat against the bottom of a tank so that no water is under that face. Will the block float to the surface? Is there a buoyant force on it? Explain.

Short Answer

Expert verified

The cube of oak wood will not float to the surface and there is no buoyant force on it.

Step by step solution

01

Understanding the buoyant force

In this problem, the concept of buoyant force will be used in order to evaluate whether the block will float to the surface or not. The buoyant force is the amount of force applied by water on a submerged object.

02

Evaluating whether the block will float to the surface

When a cube of oak wood having a smooth surface is entirely immersed in water, and one face of the cube is flat against the bottom of the water tank, then there will be no water below the cube of oak wood. Due to the absence of water, the buoyant force will not exert on the cube. So, the cube will remain at its position and doesn鈥檛 float back to the water's surface.

Thus, there is no buoyant force exerting on the cube.

A car and a truck start from rest at the same instant, with the car initially at some distance behind the truck. The truck has a constant acceleration of20m/s2, and the car has an acceleration of3.40m/s2. The car overtakes the truck after the truck has moved60.0m. (a) How much time does it take the car to overtake the truck? (b) How far was the car behind the truck initially? (c) What is the speed of each when they are abreast? (d) On a single graph, sketch the position of each vehicle as a function of time. Takex=0at the initial location of the truck.

You normally drive on the freeway between San Diego and Los Angeles at an average speed of 105 km/h (65 mi/h), and the trip takes 1 h and 50 min. On a Friday afternoon, however, heavy traffic slows you down and you drive the same distance at an average speed of only 70 km/h (43 mi/h). How much longer does the trip take?

Comparing Example 12.1 (Section 12.1) and Example 12.2 (Section 12.2), it seems that 700 N of air is exerting a downward force of on the floor. How is this possible?

In March 2006, two small satellites were discovered orbiting Pluto, one at a distance of 48,000 km and the other at 64,000 km. Pluto already was known to have a large satellite Charon, orbiting at 19,600 km with an orbital period of 6.39 days. Assuming that the satellites do not affect each other, find the orbital periods of the two small satellites withoutusing the mass of Pluto.
