Sound waves are emitted isotropically (that is, with equal intensity in all directions) from a source. The intensity of the waves 3.00 m from the source is 2.60x10 -4 W/m 2. Assuming the energy of the waves is conserved, what is the power of the source?

Ocean waves are traveling to the east at 3.4 m/s with a distance of 19 m between crests. (a) With what frequency do the waves hit the front of a boat when the boat is at anchor? Hz (b) With what frequency do the waves hit the front of a boat when the boat is moving westward at 1.0 m/s? Hz

As a boat travels at 48.0 km>h across the surface of a still lake,the waves it creates in the water have a speed of 20.1 km>h.What is the angle of the shock wave created by the waves?

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.)

Use the wave equation to find the speed of a wave given byy(x, t) = (3.00 mm) sin[(4.00 m-1)x - (7.00 s-1)t].
