A laptop is used for 4 hours. During that time, it transferred 792 kJ of energy.Calculate the power of this laptop.Give your answer in watts. Make sure to include the units in your answer.

To calculate the power of the laptop, we need to use the formula for power which is:

Power = Energy / Time

The energy transferred by the laptop is given as 792 kJ. However, the standard unit for energy in this context is joules (J), not kilojoules (kJ). So, we need to convert kilojoules to joules.

1 kJ = 1000 J

So, 792 kJ = 792 * 1000 = 792,000 J

The time is given as 4 hours. However, the standard unit for time in this context is seconds (s), not hours. So, we need to convert hours to seconds.

1 hour = 3600 seconds

So, 4 hours = 4 * 3600 = 14,400 seconds

Now we can substitute these values into the formula:

Power = 792,000 J / 14,400 s = 55 W

So, the power of the laptop is 55 watts.

To calculate the power of the laptop, we need to use the formula for power which is:

Power = Energy / Time

The energy transferred is given as 792 kJ. However, power is typically measured in watts, and 1 watt is equal to 1 joule/second. So, we need to convert the energy from kilojoules to joules.

1 kJ = 1000 J

So, 792 kJ = 792 * 1000 = 792,000 J

The time is given as 4 hours. We need to convert this to seconds because the standard unit of time in this context is seconds.

1 hour = 3600 seconds

So, 4 hours = 4 * 3600 = 14,400 seconds

Now we can substitute these values into the formula:

Power = 792,000 J / 14,400 s = 55 W

So, the power of the laptop is 55 watts.
