Hello,
I have two test questions that I missed AT school so i wrote them down. I wanted to know the correct answers as well as a short description of how they came up with that.
1) a simple pendulum consists of a mass attached to a weightless string L. For this system when undergoing small oscillation
a. frequency proportional to amplitude -->that was my original answer
b. period proportional to amplitude
c. frequency independent of mass
frequency is independent of length
My new answer from what I read and understand would be d, am i correct?
2) Simple pendulum A swings back n forth at twice the frequency of a simple pendulum B. what statement is correct?
a. B is twice as long as A
b. B is twice as massive as A
c the length of B is 4 times the length of A
d. the mass of B is 4 times the mass of A
i don't remember but i think the formula is 1/2pi * sqrt(g/L)
anyways can anyone tell me the correct answer and briefly why?
Thanks!
