hw1 At a specific point along a string the displacement of transverse wave can be described by the equation, y(t) = A sin(ωt) where A = 0.55 m and ω = 4.5 rad/s. Input an expression for the frequency.  What is the maximum y value the wave reaches in m?  Starting from t = 0, what is the first time (in seconds) that the y value will be A/2?

Part A A horizontal wire is tied to supports at each end and vibrates in its second-overtone standing wave.

HA Value Constants Part B A horizontal wire is tied to supports at each end and vibrates in its second-overtone standing wave. The tension in the wire is 5.00 N, and the node-to-node distance in the standing wave is 6.38 cm. A point at an antinode of the standing wave on the wire travels from its maximum upward displacement to its maximum downward displacement in 8.40 ms. What is the wire' mass? Express your answer with the appropriate units. 國

Ⓒ Macmillan Learning Consider the waveform expression. y (x, t) = ym sin (909t+ 0.333x + 3.71) The transverse displacement (y) of a wave is given as a function of position (x in meters) and time (t in seconds) by the expression. Determine the wavelength, frequency, period, and phase constant of this waveform. λ = T = meters seconds f = Φο = Hertz radians

A 4.95-m, 0.736-kg wire is used to support two uniform 239-N posts of equal length (Figure 1). Assume that the wire is essentially horizontal and that the speed of sound is 344 m/s. A strong wind is blowing, causing the wire to vibrate in its 5th overtone. a. What is the frequency of the sound this wire produces? b. What is the wavelength of the sound this wire produces?
