14. Calculate the time it takes a 5,200 W appliance to transfer 30,000 J of energy (1dp)
Question
- Calculate the time it takes a 5,200 W appliance to transfer 30,000 J of energy (1dp)
Solution
The formula to calculate time when power and energy are given is:
Time = Energy / Power
Given: Power (P) = 5200 W Energy (E) = 30000 J
Substitute the given values into the formula:
Time = 30000 J / 5200 W = 5.77 seconds
So, it takes approximately 5.8 seconds (to 1 decimal place) for a 5200 W appliance to transfer 30000 J of energy.
