a) A 10 kHz sound wave travels in air at T=100F, what is its velocity and wavelength? b) For the pendulum of mass m and length L derive the formula for the period T

Harmonic, sinusiodal wave propagates through a string with speed v and frequency f. At a given instant of time, two points on the string have a phase difference of π/8 rad. Calculate the distance between those two point

The displacement of a traveling wave as a function of position and time is given by; y(x,t) = 0.14 sin(25.4x-597t) where are values have proper SI Units. What is the wave speed of this wave?

Some Hawaiian tsunamis For an interval of 45 minutes, the tsunamis near Hawaii caused by the Chilean earthquake of TT 1960 could be modeled by the equation y = 8 sin -t, 6 where y is in feet and t is in minutes. (a) Find the amplitude and period of the waves. (b) If the distance from one crest of the wave to the next was 21 kilometers, what was the velocity of the wave? (Tidal waves can have velocities of more than 700 km/hr in deep sea water.)

A harmonic wave travels down a string under 60 N of tension with a mass per unit length of 0.400 kg/m. The wave has an amplitude of 3.00 cm, and a wavelength of 1.40 m. What is the average power transferred by the wave? (Give your answer in W.)
