Astring has a mass of 0.5g, and a length of 12 m. the tension in the string is 100 n a how much time does it take a pulse that is 10 cm tall and 100 cm wide to travel the entire length of the string (one way? b. a sinusoidal wave with a frequency of 30 hz and an amplitude of 20 cm now travels down the string. calculate the period and wavelength c. draw a snapshot graph and a history graph. clearly label the period, wavelength, and amplitude d. write the specific algebraic equation representations for the history graph you drew: y(t) = e. imagine that the same string is vibrated with a sinusoidal oscillation of a higher frequency. for each of the following quantities, identify whether it would increase, decrease, or stay the same explain decrease increase a. wavespeed stay the same increase decrease b. wavelength stay the same increase stay the same decrease c. period explain your reasoning:
