The answer is it will supply 1.1 x 10⁹ J of energy each second. we can calculate this by using the following equation; P = W/t <span>W = P x t </span><span>and by work energy relation; E = W = P x t </span>1 watt = 1j/s 1megawatt = 1000000 = 10⁶ j/s <span>E = 1100 x 106 x 1 </span> E = 1.1 x 10⁹ J
The doorbell transforms electrical energy into sound.
Explanation:
The doorbell MAY turn electrical energy into motion of a striker which then impacts a resonator creating sound. However all door bells do not have solenoids. Some are electronic playing recordings when activated.
