2. How much energy does a pair of 800W hair straighteners transfer every second? (1)

Answer 1

A pair of 800W hair straighteners transfer 800 Joules of energy every second.

Step-by-step explanation:

To calculate the amount of energy transferred by a pair of 800W hair straighteners every second, we use the formula:

Energy = Power x Time

Given that the power of each hair straightener is 800W, and the time is 1 second, we can substitute these values into the formula:

Energy = 800W x 1s = 800 Joules

Therefore, a pair of 800W hair straighteners transfer 800 Joules of energy every second.
