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

   Power rating on the blender = 3809.52 Watts

Explanation:

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

   Energy used by blender = Work done by electricity = 0.8 MJ =

   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

here are some information of the future of geothermal energy:

-the future of geothermal energy can pretty much be summed up with a single word: more

-scientists plan in going deeper than 120 meters

-we are hoping that one day, we will get all of our energy from renewable energy sources such as geothermal energy

hope this !
