Which of the following would have the highest power rating? 500 j of energy used in 100 seconds 1,000 j of energy used in 100 seconds 500 j of energy used in 50 seconds 1,000 j of energy used in 50 seconds

Power is defined as the work produced per unit of time. The SI unit for power is the watt, which is also equivalent to Joules per second. Given the data above, the power can be directly calculated by dividing the work (joule) by the time (second). The one that gives the highest power of 20 watts is 1,000 J of energy used in 50 seconds.

Julia would be observing a. static electricity was caused by her sweater rubbing against her shirt and transferring electrons. she didn't touch anything metal, so that would cancel out b.she most likely didn't rub her sweater against her hair either, so that cancels out c.she also didn't scoot across the carpet while trying to take her sweater off, that cancels out d.so that leaves a.a. is correct.
