Identify the scenarios below as to whether they would increase, decrease, or not change
the frequency in which a string vibrates and thus change its pitch. Assume that no other
changes are happening.
1. Tightening a string for greater tension
2. Replacing a thin string with a thick string
3. Increasing the effective length of the string

Acentrifuge in a medical laboratory rotates at an angular speed of 3,700 rev/min. when switched off, it rotates through 54.0 revolutions before coming to rest. find the constant angular acceleration (in rad/s2) of the centrifuge. your response is within 10% of the correct value. this may be due to roundoff error, or you could have a mistake in your calculation. carry out all intermediate results to at least four-digit accuracy to minimize roundoff error. rad/s2
