Answer:
We conclude that star moving toward observer.
Explanation:
According to the theory of doppler effect of light.
There are two kind of shift 1 ) Blue shift 2 ) Red shift, in which
1 ) if source of light moving toward observer so the apparent frequency of light increase( wavelength decrease ). This is which we call blue shift
2 ) if the distance between source and observer is increase, so the apparent frequency of light decrease ( wavelength increase ). This is which we call red shift.
Here, in our case wavelength of H-star is decrease so we can say that star moving toward observer ( Blue shift ).
When it rains, dust particles and oil residues float on the water and this reduces the traction of tires.
<h3>What
is traction?</h3>
This concept refers to a force between the tires and road that causes the movement of the wheels or vehicle is slower.
<h3>What happens with traction when it rains?</h3>
It is well-known more accidents occur when it rains, which is caused by cars slidding on the road. This is because when it rains traction or the grip of the wheel drastically reduces.

Answer:
Explanation:
Given
Orbital speed is v
Mass of planet is m
Radius of circular orbit is r
suppose M is the mas of satellite then centripetal force on satellite is equal to the Gravitational Pull.
where G=gravitational constant
thus on solving we get
