What determines the output voltage and the current of a transformer? the number of turns in the primary and secondary coils the direction of the current in the primary and secondary coils the ferromagnetic material of the primary coil the strength of the current in the primary coil

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.)
