Multiple choice questions about SHM

AI Thread Summary
Reflection applies to both transverse and longitudinal waves, confirming option c as correct. Increasing the mass of the bob on a spring will increase the period of vibrations, as indicated by the formula T=2π√(m/k). Releasing a spring from progressively larger displacements will also increase the maximum velocity of the bob, based on the relationship vmax=2π*displacement/T. The discussion emphasizes the nature of light as a transverse wave and sound as a longitudinal wave. Overall, the answers provided for the homework questions are affirmed as correct.

Homework Statement


1.Reflection goes with
a. longitudnal wave
b.trasnsverse wave
c. both
d.neither
2.
if mass of teh bob on a springs are increased, howe whould that affet the period of the vibrations?

3. if a spring is released fr. progressively larger displacments, how owould this affect eh e max. velocity of teh bob.

Homework Equations





The Attempt at a Solution



1. transverse, because reflection refers to light right?
2. increase becase T=2pi(sq.root(m/k))
3.increase because vmax=2pi*displacement/(T)

For the answer to number 1) What kind of wave is light? Does light reflect? What kind of wave is sound? Ever hear an echo? (Check Wikipedia if you don't know the answers to my questions)

Your answer to 2) and 3) are correct.
 
yes it does. light is transverse and sounds is longitudinal...so i guess the answer is c. both.

Yup!
 
thank you.
 
Thread 'Collision of a bullet on a rod-string system: query'

Thread 'Collision of a bullet on a rod-string system: query'

In this question, I have a question. I am NOT trying to solve it, but it is just a conceptual question. Consider the point on the rod, which connects the string and the rod. My question: just before and after the collision, is ANGULAR momentum CONSERVED about this point? Lets call the point which connects the string and rod as P. Why am I asking this? : it is clear from the scenario that the point of concern, which connects the string and the rod, moves in a circular path due to the string...

Thread 'A cylinder connected to a hanged mass'

Thread 'A cylinder connected to a hanged mass'

Let's declare that for the cylinder, mass = M = 10 kg Radius = R = 4 m For the wall and the floor, Friction coeff = ##\mu## = 0.5 For the hanging mass, mass = m = 11 kg First, we divide the force according to their respective plane (x and y thing, correct me if I'm wrong) and according to which, cylinder or the hanging mass, they're working on. Force on the hanging mass $$mg - T = ma$$ Force(Cylinder) on y $$N_f + f_w - Mg = 0$$ Force(Cylinder) on x $$T + f_f - N_w = Ma$$ There's also...
