Answer:
The time is 0.563 ns.
Explanation:
Given that,
Index of refraction of glass = 1.41
Distance = 12.0 cm
Angle = 33.0°
We need to calculate the refraction angle
Using Snell's law

put the value into the formula



We need to calculate the velocity of beam in glass
Using formula of velocity

Put the value into the formula


We need to calculate the time
Using formula of distance





Hence, The time is 0.563 ns.
Answer:
P-waves travel through liquids and solid while S-waves only travel through solids.
Explanation:
Scientists are able to use the fact that P-waves travel through both solids and liquids and waves travel through only solids to determine what makes the different layers of the Earth.
They will both hit the ground at the same time because gravitational acceleration for all objects is the same.
40V because it will provide the same amount of power.
