Answer:
The index of refraction of the liquid is 1.35.
Explanation:
It is given that,
Critical angle for a certain air-liquid surface,
Let n₁ is the refractive index of liquid and n₂ is the refractive index of air, n₂ =1
Using Snell's law for air liquid interface as :
So, the index of refraction of the liquid is 1.35. Hence, this is the required solution.
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
