Final answer:
The energy transfer per second for a power shower rated at 10 kW is 10,000 joules, as power is the rate of energy transfer and 1 kW is equal to 1,000 W (watts), with 1 W equivalent to 1 joule per second.
Step-by-step explanation:
The question asks to calculate the energy transfer per second for a power shower with a rating of 10 kW (kilowatts). In physics, power is defined as the rate at which energy is transferred or converted. The unit of power is the watt (W), which is equivalent to one joule per second (J/s). Therefore, a power rating of 10 kW means that the power shower transfers 10 kilowatts of energy every second.
Since 1 kW equals 1,000 watts, to find the energy transfer in joules per second, we simply convert kilowatts to watts:
10 kW = 10,000 W
Hence, the energy transfer per second is 10,000 joules, because one watt equals one joule per second.
