Answer: a) 1.98inch
b) 2.737 2.44
c) 0.497inch
d) 1.58inch
Explanation:
Solution is attached in the pictures below
You are correct, the answer is C.
Good insulators are materials that do not allow heat, electricity, light or sound pass through easily. Materials like steel and silver (which are metals) are not good insulators because they make good conductors. They easily allow heat, electricity and the like pass through them.
Thus, the answer is letter C. Rubber.
Answer:
The no. of revolutions does the tub turn while it is in motion is = 52.51 revolutions
Explanation:
Given data
= 0
= 5 
Time taken = 7 sec
(1). The angular acceleration is given by



We know that from the equation of motion


-------- (1)
(2). The angular acceleration is given by


- 0.357 
We know that from the equation of motion


= 35.01 rev ------- (2)
Total no of revolution made by the machine is

17.5 + 35.01
52.51 rev
Therefore the no. of revolutions does the tub turn while it is in motion is = 52.51 rev
