A resistance R and a 4.3 H inductance are in series across a 60-Hz ac voltage. The voltage across the resistor is 20 V and the voltage across the inductor is 21 V. Assume that all voltages in this problem are rms voltages. (a) What is the resistance R

Atank has a shape of a cone with a radius at the top of 2 m and a height of 5 m. the tank also has a 1 m spout at the top of the tank. the tank is filled with water up to a height of 2 m. find the work needed to pump all the water out the top of the spout. (use 9.8 m/s2 for g and the fact that the density of water is 1000 kg/m3.)

You throw a baseball directly upward at time =0 at an initial speed of 14.9 m/s. what is the maximum height the ball reaches above where it leaves your hand? ignore air resistance and take =9.80 m/s2.
