Final answer:
A hairdryer rated at 1500 W requires 450,000 Joules of energy to operate for 5 minutes.
Step-by-step explanation:
A hairdryer rated at 1500 W requires a certain amount of energy to operate. To calculate the energy required, we can use the formula:
Energy (in joules) = Power (in watts) × Time (in seconds)
First, we need to convert the time from minutes to seconds. Since there are 60 seconds in a minute, 5 minutes is equal to 300 seconds. Plugging the values into the formula:
Energy = 1500 W × 300 s
Simplifying the calculation:
Energy = 450,000 Joules
Therefore, a hairdryer rated at 1500 W requires 450,000 Joules of energy to operate for 5 minutes.
