This is a trick question:
The Doppler effect states that as you move closer to the source, the frequency of light(or sound/waves in general) increases, but technically the speed of light is always the same speed, even if you are moving at the speed of light.
Thus, the answer would be something along the lines of <u>don't change</u>.
Answer:
A board is hung from two springs, as shown in the figure above, with the board in equilibrium. Each spring has a spring constant of 10,000 N/m. How far will each spring stretch when a person of mass 50 kg sits on the board and the board again comes to equilibrium?

Answer:
Explanation:
acceleration and mass are indirectly proportional so as the mass increases the acceleration will decrease since it doubles them the acceleration withh ecrease to the half :)
This feather weighs heavier on earth than on Mars hence it is better that the feather falls on you in Mars than on earth.
<h3>What is weight?</h3>
The term weight refers to the effect of the gravitational pull on an object. The acceleration due to gravity on earth is about 9.8m/s^2. The weight of this feather on earth is about 4.80 Kg * 9.8m/s^2 = 47 N
On the planet Mars, the weight is;
4.80 Kg * (0.38 * 9.8m/s^2) = 18 N
This feather weighs heavier on earth than on Mars hence it is better that the feather falls on you in Mars than on earth.
