A 210 g oscillator in a vacuum chamber has a frequency of 2.0 Hz . When air is admitted, the oscillation decreases to 60% of its initial amplitude in 50 s.
Q.
How many oscillations will have been completed when the amplitude is 30% of its initial value?
Express your answer in oscillations.
Alright Dude, If that worked for you... don't forget to give THUMBS
UP.(that will work for me!)
Please Vote...
If I missed something feel free to leave a comment.
atleast before giving down vote.
and, Thanks for using homeworklib- Smarter way to study.

Problem 15.63 A molecular bond can be modeled as a spring between two atoms that vibrate with simple harmonic motion. The figure shows an SHM approximation for the potential energy of an HCI molecule. Because the chlorine atom is so much more massive than the hydrogen atom it is reasonable to assume that the hydrogen atom (m-1.67x10-27kg) vibrates back and forth while the chlorine atom remains at rest.
