Answer:
We first to know that if the wheel rotates from rest means that at t=0 the velocity and the angle rotated is 0.
Then, we know:
Integrating 2 times, we have:
For the first 27.9 s, we have:
w = 37.107 rad/s
angle = 517.6426 rad
For the next seconds, according to the text, the angular velocity is constant so
w = 37.107 rad/s and hence, integrating:
Then, the time remaining is:
53.5 - 27.9 = 25.6
So for the next 25.6 seconds we have:
Finally, we add the 2 angles and we have as a result:

Answer</h2>
Causality means reason behind the process
<h2>
Explanation</h2>
In the scientific inquiries, scientists perform different activities with the help of previous knowledge and scientific ways to renew the knowledge or discover the new ideas. It is a common belief that in every process that is happening in nature have many functions and reasons behind it. Scientists are always in the struggle to find these reasons and their importance regarding their happenings. When the scientists are in hurry to know about the causality, it means they are helping the scientific knowledge with the discovery of new reasons for happens.
Answer:
As light travels in a straight line at a constant speed, it's acceleration is <u>0 m/s²</u>.
There is no rate of change of speed, so there is no acceleration.
- <u>0 m/s²</u> is the right answer.
