Question

Chapter 33, Problem 1OQ

To determine

The cause of slowing down of universe expansion.

Expert Solution & Answer

Answer to Problem 1OQ

Solution:

The gravity is the factor which was assumed to be the cause of the slowing down of the expansion of the universe in earlier days. Therefore, option c is correct.

Explanation of Solution

Option a is wrong since, there is no frictional force present.

The second law of thermodynamics states that the randomness of the universe increases with time. So, this is not the cause of slowing down. Therefore, option b is wrong.

Due to the gravity or gravitational force, the process of expansion may slow down due to the gravitational attraction between objects. So, option c is correct.

The electromagnetic force may be either attractive or repulsive. So, option d is wrong.

Conclusion:

Option c is correct.

3.63 • Leaping the River II. A physics professor did daredevil stunts in his spare time. His last stunt was an attempt to jump across a river on a motorcycle (Fig. P3.63). The takeoff ramp was inclined at 53.0°, the river was 40.0 m wide, and the far bank was 15.0 m lower than the top of the ramp. The river itself was 100 m below the ramp. Ignore air resistance. (a) What should his speed have been at the top of the ramp to have just made it to the edge of the far bank? (b) If his speed was only half the value found in part (a), where did he land? Figure P3.63 53.0° 100 m 40.0 m→ 15.0 m
