The 250 - turn primary coil of a step‑down transformer is connected to an AC line that is 120.0 V (rms). The secondary coil is to supply 12.0 A (rms) at 9.60 V (rms). Assuming no power loss in the transformer, what is the number of turns N s in the secondary coil? N s = turns What is the rms current i p, rms in the primary coil?

Aprojectile is launched from ground level with an initial velocity of v 0 feet per second. neglecting air resistance, its height in feet t seconds after launch is given by s equals negative 16 t squared plus v 0 t. find the time(s) that the projectile will (a) reach a height of 192 ft and (b) return to the ground when v 0equals112 feet per second. (a) find the time(s) that the projectile will reach a height of 192 ft when v 0equals112 feet per second. select the correct choice below and, if necessary, fill in the answer box to complete your choice.
