Two wave pulses travel on a string toward each other. The wave pulses can be described as y1 = 5/(((kx − ωt)^2) 2) and y2 = −5/(((kx + ωt − 6)2 )+2)' , where k = 1 rad/m and ω = 8 rad/s. At what instant do the two cancel everywhere? (Assume x is in meters and t is in seconds.) ???s At what point do the two pulses always cancel? ???m

Two wires are parallel, and one is directly above the other. Each has a length of 40.8 m and a mass per unit length of 0.0183 kg/m. However, the tension in wire A is 53.4 × 102 N, while the tension in wire B is 4.08 × 102 N. Transverse wave pulses are generated simultaneously, one at the left end of wire A and one at the right end of wire B. The pulses travel toward each other. How much...

A pendulum consists of a string of length L and a mass m hung at one end and the mass oscillates along a circular arc. Part a) Familiarize yourself with the derivation of omega = Squareroot g/L to hold. i) Explain succinctly how the angular frequency of oscillation omega = Squareroot g/L comes about from Newton's Law, where g is the gravitational acceleration. ii) One assumption required is the small angle approximation: sin theta = theta and cos theta =...
