Question

0.8 mj of energy are used by a blender in 3 and a half minutes what is the power rating on the blender

Answer 1

Power rating on the blender = 3809.52 Watts

Step-by-step explanation:

We have expression for power equal to ratio of work and time,

Energy used by blender = Work done by electricity = 0.8 MJ =
`0.8*10^6J=800000J`

Time of using blender = 3.5 minutes = 210 seconds

So power of blender = 800000/210 = 3809.52 Watts

Power rating on the blender = 3809.52 Watts
