Answer 2

Answer:

The amount of energy that the television consumes is 5542.17 J

Explanation:

Solution;

Given;

Output work = 4600 J

Efficiency = 83 %

Now,

We know,

Efficiency = Output work/Input work x 100

or, 83 = 4600/Input work x 100

or, 83 = 460000/Input work

or, 83xInput work = 460000

or, Input work = 460000/83

or, Input work = 5542.17 J
