A rocket, starting from rest, travels straight up with an acceleration of 59.7 m/s2. When the rocket is at a height of 575 m, it produces sound that eventually reaches a ground-based monitoring station directly below. The sound is emitted uniformly in all directions. The monitoring station measures a sound intensity I. Later, the station measures an intensity 1 3 I. Assuming that the speed of sound is 343 m/s, find the time that has elapsed between the two measurements.

You have a resistor and a capacitor of unknown values. first, you charge the capacitor and discharge it through the resistor. by monitoring the capacitor voltage on an oscilloscope, you see that the voltage decays to half its initial value in 2.70 miss . you then use the resistor and capacitor to make a low-pass filter. what is the crossover frequency fc?
