A 3kW kettle boils water in 4 minutes. Does this use more electrical energy than a 150W fridge left on 1 hour?

The kettle used more electrical energy

Explanation:

We need to find the appliance that used more electrical energy.

To solve this problem, we need to find the amount of electrical energy used by both appliances.

For the kettle;

 Power consumed  = 3kW

  Time  = 4minutes

    Electrical energy  = Power x time

    Convert 4min to hr;

              60min  = 1hr

               4min   =   = hr

  Electrical energy  = 3 x   = 0.2kwh

For the fridge;

  Power consumed  = 150W = 0.15kW

   Time  = 1hr

     Electrical energy  = 0.15kW x 1hr = 0.15kWh

it's when something is going so fast it makes a loud noise, breaking the sound barrier, for example: a jet makes a loud noise, not only cause of the jet but because they reached a point where they went so fast that you can year the noise from various parts, kinda like a police car, lets say the car was going   so fast that you hear the siren of the cop car right next to you, but the car is probably a mile a way, it's cos the siren was next to you a few seconds if you understand me
