Answer:
11700j
Explanation:
add the two because the plate has to maintain the temp.
2700+9000=11700
The first choices are correct, because the second choices could happen by things other than light.
You would divide 6 into 1000 so your answer is B. 166
Answer:
<h2>Total thermal energy for all air molecules is 59.54 J</h2>
Explanation:
As we know that the ball comes to rest finally so here we can say that
initial total potential energy of the ball is transferred to the air molecules
So here we have


So here we have

So all the gravitational potential energy of the ball will convert into thermal energy of air molecules which is equal to 59.54 J
