<h2>Hello!</h2>
The answer is C. The television uses 6,588,000 J less than the lamp.
<h2>Why?</h2>First, we must know that 1 Wh( Watt consumed in 1 hour) = 3600 J
Wh is the unit that express the energy amount of consumed in 60 minutes/ 1 hour.
So,
From the enunciate information we can calculate the energy consumed by the lamp and the television.
For the lamp, we have that it left on for 24 hours and it has a power of 120
For the television, we have that it left on for 3 hours and it has a power of 350W
Calculating the energy consumed (Wh) we have:
and converting it to Joule, we have:
Doing the same for the television, we have:
and converting it to Joule, we have:
Finally, we have
:
Then having calculated both consume, we have that the television uses 6,588,000 J less than the lamp.
