A coil is connected in series with a 12.5 kΩ resistor. An ideal 75.0 V battery is applied across the two devices, and the current reaches a value of 1.79 mA after 6.35 ms. (a) Find the inductance of the coil. (b) How much energy is stored in the coil at this same moment?

22. the top of a cliff is located a distance h above the ground. at a distance h/2 there is a branch that juts out from the side of the cliff, and on this branch a bird's nest is located. two children throw stones at the nest with the same initial speed, one stone straight downward from the top of the cliff and the other stone straight upward from the ground. in the absence of air resistance, which stone hits the nest in the least amount of time?
