can anyone help me with these two questions

the answer is D but i dont understand why it cant be B as Momentum = mass x velocity and since mass is constant velocity increases


just tell me which formula do i use

Top one.
just look at the formula in the back and look for the ones you know the value of (T)
1/2m<c>^2 = 3/2KT

Where K is a constant

Second one, answer is B. As time period is constant. Therefore frequency is also constant.
