Answer:
Therefore, it takes approximately 0.5 seconds for the 2.86kW toaster to do 1430J of work.
Step-by-step explanation:
To calculate the time it takes for the toaster to do 1430J of work, we can use the formula:
Work = Power * Time
Given:
Power = 2.86kW (kilowatts)
Work = 1430J (joules)
Time = unknown
First, we need to convert the power from kilowatts to watts:
Power = 2.86kW * 1000 = 2860W
Now we can rearrange the formula to solve for Time:
Time = Work / Power
Plugging in the given values:
Time = 1430J / 2860W
Time ≈ 0.5 seconds
