How much energy is tr ansferred by đ cooker with a power rating of 2000 W in half an hour?Give your answ er in kilojoules, (kJ). Enter a number

## Step1:First, we need to convert the time from minutes to seconds because the power rating is given in Watts, which is Joules per second. There are 60 seconds in a minute, so half an hour is seconds.## Step2:Next, we will calculate the energy transferred using the formula for power, which is energy divided by time. Rearranging this formula gives us energy equals power times time.### ## Step3:Substitute the given power and time into the formula:### ## Step4:The result will be in Joules. To convert this to kilojoules, we divide by 1000 because there are 1000 Joules in a kilojoule.
