Answer:
Nope!
Explanation:
The amplitude of a wave does not affect the speed at which the wave travels. Both Wave A and Wave B travel at the same speed. The speed of a wave is only altered by alterations in the properties of the medium through which it travels.

Answer:
The speed of galaxy relative to the earth is
Explanation:
Given :
Observed frequency
Actual frequency
For finding the speed of galaxy relative to the earth.
From the doppler effect of light,
Where , relative speed
Therefore, the speed of galaxy relative to the earth is
She recoil at a high speed than a low
Here space craft is moving with constant velocity
Now due to gas leakage it will have acceleration perpendicular to velocity
it is given that acceleration is always perpendicular to velocity
So it will neither increase nor decrease the velocity
it will only change the direction of the motion
so it is the centripetal acceleration of the space craft
in this case we will say that path of the space craft will be circular path
<em>So it will perform Uniform Circular Motion and its path will be a circle</em>
The angle of the Earth on its axis making the sun to beam on the Northern and Southern Hemispheres differently. When one side is fronting the sun, the other is on the side the darkness, so, when it's Winter in the northern half, it's Summer in the southern half.
