A resistance R and a 3.1 H inductance are in series across a 60-Hz ac voltage. The voltage across the resistor is 26 V and the voltage across the inductor is 39 V. Assume that all voltages in this problem are rms voltages. (a) What is the resistance R

it's when something is going so fast it makes a loud noise, breaking the sound barrier, for example: a jet makes a loud noise, not only cause of the jet but because they reached a point where they went so fast that you can year the noise from various parts, kinda like a police car, lets say the car was going   so fast that you hear the siren of the cop car right next to you, but the car is probably a mile a way, it's cos the siren was next to you a few seconds if you understand me
