Chapter 13, Problem 78GP
Helioseismology In 1962, physicists at Cal Tech discovered that the surface of the Sun vibrates due to the violent nuclear reactions that roil within its core. This has led to a new field of solar science known as helioseismology. A typical vibration of the Sun is shown in Figure 13.39; it has a period of 5.7 minutes. The blue patches in Figure 13-39 are moving outward; the red patches are moving inward. (a) Find the angular frequency of this vibration. (b) The maximum speed at which a patch of the surface moves during a vibration is 4.5 m/s. What is the amplitude of the vibration, assuming it to be

308 million people live on the planet Trigonometry. One day, as an experiment, all 308 million people climbed on tables and jump off (t=0) at the same time. The shock wave as they hit the surface starts the entire Trigonometry planet vibrating in such a way that its surface first moves down from its normal position, and then moves up an equal distance above its normal position. The lowest point the ground reached was 50 feet below the normal position, which occurred at t= 13.5 minutes. Assume the displacement of the surface was a sinusoidal function of time.
A. What is the amplitude of the vibration? Use a complete sentence to explain what the amplitude is and what it represents in the context of this scenario.
