Question

0.8mj of energy are used by a blender in 3 and a half minutes. What is the power rating of the oven

Answer 1

Given that 0.8 MJ of energy is used in 3.5 minute of time

Now we need to find the power rating

so here power consumed is given by rate of energy which is defined by formula

`Power = (Energy)/(time)`

now we will plug in all given data

`Energy = 0.8 MJ = 8 * 10^5 J`

`time = 3.5 min = 3.5 * 60 = 210 s`

now we will find the power

`P = (8 * 10^5)/(210)`

`P = 3809.5 Watt`

`P = 3.81 kW`

so it will consume total 3.81 kW power
