A 100-W (watt) light bulb has resistance R= 146 (ohms) when attached to household current, where voltage varies asV = V, sin(2n fr). where Vo = 110 V. f = 60 Hz. The power supplied to the bulb is P = J/s (joules per second) andthe total encrgy expended over a time period [0, 7] (in seconds) is%3!U =P() dttoCompute U if the bulb remains on for 6 hours.(Use decimal notation. Give your answer to one decimal place.)U =
