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

A6.0-kilogram cart initially traveling at 4.0 meters per second east accelerates uniformly at 0.50 meter per second squared east for 3.0 seconds. what is the speed of the cart at the end of this 3.0 second interval? (1) 1.5 m/s (3) 3.0 m/s (2) 5.5 m/s (4) 7.0 m/s

How does changing the frequency affect the energy of the wave?
