Aspear of length 8.0 m is thrown with high velocity through the open windows of a room 6.0 m long. (a) how fast must the spear move so that it barely fits in the room when passing through? (b) in the spear’s reference frame, which occurs first: (1) the front of the spear leaving the room or (2) the rear of the spear entering the room? what is the time difference in ns? hint: from (a) these two events occur simultaneously for someone at rest in the room.

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?
