I think it would be at 3 or 6 but I would go with 3 not really sure tho
<span>So we want to know how much work is needed to move a charge Q=3C for a distance r=0.01m trough a potencial difference U=9V. Work of electric potential is defined as W=Q*U and we can now simply put in the numbers. We get: W=3C*9V=27J. So the correct answer is (2) 27J. </span>
Shiddd ion even know but can you like my comment?
To solve this problem, apply the concepts related to the calculation of the work performed according to the temperature change (in an ideal Carnot cycle), for which you have to:
Where,
C = Heat capacity of the Brick
= Cold Temperature
= Hot Temperature
Integrating,
Our values are given as
Replacing,
Therefore the work perfomed by this ideal carnot engine is 58kJ
