The power in an electrical circuit is given by the equation P = I^2R, where I is the current flowing through the circuit and R is the resistance of the circuit. What is the power in a circuit that has a current of 12 amps and a resistance of 100 ohms? *

The safe load, l, of a wooden beam of width w, height h, and length l, supported at both ends, varies directly as the product of the width and the square of the height, and inversely as the length. a wooden beam 4 inches wide, 9 inches high, and 240 inches long can hold a load of 6810 pounds. what load would a beam 3 inches wide, 8 inches high, and 144 inches long, of the same material, support? (round off your answer to the nearest integer.)
