A64.0 kg daredevil exhibitionist hangs on to the end of a long bungee cord attached to the railing of the brooklyn bridge and oscillates vertically. (do not try this! ) the spring constant of the bungee cord is 113 n/m, and the system's damping constant is 0.113 kg/s.
how long does it take for the oscillation amplitude to decrease to 93.8% of its initial value?
what is the frequency of oscillation?

What is the name of the perceived change in a sound wave’s frequency due to motion between the observer and the sound source?

Light from two different sources are incident upon the same side of a polarizing filter. light from one source is polarized with total intensity ip, while light from the other source is unpolarized with total intensity iu. as you rotate the polarizing filter through 360 degrees, the intensity of the transmitted light on the other side varies by a factor of 9. what is the relative intensity of the initial polarized source to the unpolarized source, or ip/iu?
