Two waves traveling on a string in the same direction both have a frequency of 125 Hz, a wavelength of 2 cm, and an amplitude of 0.05 m. What is the amplitude of the resultant wave if the original waves differ in phase by each of the following values?
Rope BCA passes through a pulley at point C and supports a crate at point A. Rope segment CD supports the pulley, What is the angle required for equilibrium?
Two traveling waves with the same amplitude A, frequency f, and wavelength, but out of phase with each other by one quarter of a wavelength, aWrite the equation of the resulting traveling wave
A 25g ball is fired with an initial speed v1 toward a 150g ball that is hanging motionless from a 1.30m string. The balls have a perfectly elastic collision. As a result, 150 g ball swings out until the string makes an angle of 37° with vertical. ..
