Calculate the energy transfers in joules by a 4kW by appliances left for 120 minutes

1 answer:

6 0

Answer:

When work is done on an object, energy is transferred. The rate at which this energy is transferred is called power. So the more powerful a device is, the more energy it will transfer each second. This is important when considering the total cost of electricity used as shown on an electricity bill.

Explain the relationship between energy and the potential to do work

Alenkinab [10]

Potential energy is the energy possessed by a body by virtue of its position or configuration . And energy is the capacity of doing work since power is work divided by time therefore change in potential energy divided by time is equal to the power of the object.
