2) The speed of sound v in a medium depends on its wavelength 1, the young modulus E, and the density p, of the medium. Use the method of dimensional
analysis to derive a formula for the speed of sound in a medium. (Unit for
Young Modulus E: kgm's?)​

How is sound energy produced a. vibrating objects b. objects being heated c. temperature differences d. stationary objects

Abird flies directly overhead from where you stand at an altitude of 300.0 m and at a speed horizontal to the ground of 20.0 m/s. the bird has a mass of 2.0 kg. the radius vector to the bird makes an angle \thetaθ with respect to the ground. the radius vector to the bird and its momentum vector lie in the xyxy-plane. what is the bird’s angular momentum about the point where you are standing?

Awave with a frequency of 500 hz is traveling at a speed of 100 m/s.what is the wavelength?
