Question
1
![**Question:**
A star rotates in a circular orbit about the center of its galaxy. The radius of the orbit is \(4.8 \times 10^{20}\) m, and the angular speed of the star is \(8.1 \times 10^{-15}\) rad/s. How long (in years) does it take for the star to make one revolution around the center?
**Diagram Explanation:**
The diagram shows a spiral pattern representing a galaxy with a circular orbit traced by a star. There are directional arrows indicating the rotation. The radius (\(r\)) of the orbit is marked, emphasizing the circular path around the center of the galaxy.
**Calculation Section:**
(b) The formula to calculate the time for one revolution is \( T = \frac{2\pi}{\omega} \), where \(\omega\) is the angular speed. Convert this time from seconds to years for the final answer.
**Inputs:**
- Number: [Input box]
- Units: [Dropdown selector for units, e.g., years]](https://content.bartleby.com/qna-images/question/c9819384-7ac8-4a35-b95a-106c2e89eec6/43fbe9d9-564e-42d9-94f5-4709c9ef7f72/hbd09j4_thumbnail.jpeg)

In the figure above on the right, block 1 of mass m1 slides along an x-axis on a frictionless floor at speed 4 m/sec.Then it undergoes a one-dimensional elastic collision with stationary block 2 of mass m2 = 2m1. Next, block 2 undergoes a one-dimensional elastic collision with stationary block 3 of mass mz = 4m1. What then is the speed of block 3? Answer: 16 m/sec or 1.78 m/sec.arrow_forward
