E.g., if the answer to 1 is A and the answer to 2 is G, enter AG. You only have 4 tries. A) E) B) F) C) G) D) H) - نه 10 m 1.0 m 0.5 1,0 m 1,0 m We...
Consider two identical and symmetrical wave pulses on a string. Suppose the first pulse reaches the fixed end of the string and is reflected back and then meets the second pulse. When the two pulses overlap exactly, the superposition principle predicts that the amplitude of the resultant pulses, at that moment, will be what factor times the amplitude of one of the original pulses? 0 1 -2 -1
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
At t = 0, the instantaneous position of two pulses moving along a taut string with a speed v = 23.2 cm/s are as shown in the diagram below. Each unit on the horizontal axis is 4.0 cm and each unit on the vertical axis is 3.0 cm. (The peak of pulse 2 is exactly on a half unit of the horizontal axis.) (a) At what location will the resultant of the two pulses have maximum amplitude? cm (b) At...

These two waves travel along the same string: y1 = (3.73 mm) sin(1.62πx - 350πt) y2 = (5.43 mm) sin(1.62πx - 350πt + 0.768πrad). What are (a) the amplitude and (b) the phase angle (relative to wave 1) of the resultant wave? (c) If a third wave of amplitude 5.18 mm is also to be sent along the string in the same direction as the first two waves, what should be its phase angle in order to maximize the amplitude...
By wiggling one end, a sinusoidal wave is made to travel along a stretched string that has a mass per unit length of 22.0 g/m. The wave may be described by the wave function y 0.20 sin (0.90x-42) where x and y are in meters and t s in seconds. 1. (a) Determine the speed of the wave. Is the wave moving in the +x direction or the -x direction? b) What is the tension in the stretched string? (c)...
A 200 Hz harmonic wave with an amplitude equal to 2 cm moves along a 40 m long string that has a mass of 120 grams and a tension of 50N. Considering that there is no energy lost, find: the power transmitted past a given point on the string and total average energy on a 20-m long segment of the string If the energy is lost in the process, the amplitude of the wave decreases as it travels along the...
