Answer:
The wavelength in vacuum is equal to 428.8 nm.
Explanation:
Given that,
The wavelength of light, 
The refractive index of glass, n = 1.51
We need to find the wavelength in vacuum. The relation between wavelength and refractive index is given by :

So, the wavelength in vacuum is equal to 428.8 nm.
There are plates under the surface that shift when there is interruption on the surface <span />
Answer:
Circulatory System
Explanation:
The respiratory system works with the circulatory system to provide tis oxygen and to remove the waste products of metabolism. It also helps to regulate PH of the blood. Respiration is the sequence of events that result in the exchange of oxygen and carbon dioxide between the atmosphere and the body cells.
Momentum definition: the quantity of motion of a moving body, measured as a product of its mass and velocity.
Impulse definition: change of momentum of an object when the object is acted upon by a force for an interval of time
These are the definitions.
Hope this helps!

Answer:
Part a)

Part b)

Explanation:
Part a)
Since the diver is moving under gravity
so here its acceleration due to gravity will be uniform throughout the motion
so here we will have

here we have




Part b)
at highest point of his motion the final speed will be zero
so we will have
