Question

1a. A simple pendulum of length L and mass M has frequency f. Toincrease its frequency to 2f: decrease itslength to L/4
decrease itslength to L/2
increase itslength to 4L
increase itslength to 2L
decrease its massto < M/4 1b. Two identical but separate strings, with the same tension,carry sinusoidal waves with the same frequency. Wave A has aamplitude that is twice that of wave B and transmits energy at arate that is _______ that of wave B. fourtimes
eighttimes
twice
one-fourth
half




1C. The amplitude and phase constant of an oscillator aredetermined by: the initialdisplacement alone
both the initialdisplacement and velocity
the initialvelocity alone
the angularfrequency
the frequency I chose: both the initial displacement and velocity.

I'll appreciate your help. Do try to explain ur answer. I'll rateimmediately.
