A television that is 83% efficient provides 4 600) of useful energy. How much energy

does it consume?

Total energy consume will be equal to 5542.175 j

Explanation:

We have given efficiency of the television is 83% = 0.83

Now it is given that useful energy is 4600 joule

We have to find the total energy consume

We know that efficiency is equal to ratio of  useful energy to total energy consume

So

total energy consume =  5542.175

So total energy consume will be equal to 5542.175 J

electrical power

gpe = mass x gravity constant x height or… gpe = mgh

where… mass: measured in kilograms (kg)

gravity: gravity constant on earth = 10.00 m/s2

height: measured in meters (m)

gpe: measured in joules (j) or kilojoules (kj)

how do you solve gpe?

gravitational potential energy (gpe) is the energy an object has because of its position above the. ground.

gpe = mass x gravity constant x height or… gpe = mgh.
