(a) A heavy cord is vibrating in its fundamental mode and under a tension of 195 N. When a vibrating tuning fork is placed near the cord, a beat frequency of 4.96 Hz is heard. If the cord is 2.00 m long and has a mass of 0.0100 kg, determine the possible frequencies (in Hz) of the tuning fork. (Round your answers to at least the nearest integer.) lower frequency = ?????Hz higher frequency = ?????Hz   (b) The tension in the cord is now adjusted such that when it vibrates in the fundamental mode, no beats occur when the tuning fork is brought near. Given the two possible tuning fork frequencies found above, determine the two possible tensions (in N) in the cord that will allow this. lower tension = ?????N higher tension = ?????N

Seiche

A seiche is an oscillating standing wave in a body of water. The term seiche pronounced saysh) can be understood by the sloshing of water back and forth in a swimming pool. The same phenomenon happens on a much larger scale in vast bodies of water including bays and lakes. A seizure can happen in any enclosed or semi-enclosed body of water.
