Two hover pucks collide in an off-centered collision and stick to one another via velcro. When they do so, they rotate in place. Consider what was just stated, but suppose we replace both hover pucks with pucks that are the same size as the originals but twice as massive. Otherwise, we keep the experiment the same. Compared to the pucks first mentioned, this pair of pucks will rotate:.
A) twice as fast.
B) one-half as fast.
C) at the same rate.
D) one-fourth as fast.
E) four times as fast.
Explain reasoning.

The frequency of the fundamental of the guitar string is 320 hz. at what speed v do waves move along that string?

Two loudspeakers, 5.5 m apart and facing each other, play identical sounds of the same frequency. you stand halfway between them, where there is a maximum of sound intensity. moving from this point toward one of the speakers, you encounter a minimum of sound intensity when you have moved 0.33 m . assume the speed of sound is 340 m/s.part a) what is the frequency of the sound? part b) if the frequency is then increased while you remain 0.21 m from the center, what is the first frequency for which that location will be a maximum of sound intensity? express your answer to two significant figures and include the appropriate units.
