The change in internal energy of the system is +30 J
Explanation:
We can solve this problem by using the first law of thermodynamics, which states that the change in internal energy of a system is given by the equation:
where
is the change in internal energy
Q is the heat absorbed by the system (positive if it is absorbed, negative if it is released)
W is the work done by the system (positive if it is done by the system, negative if it is done by the surroundings on the system)
Therefore, in this problem, we have
(heat released by the system)
(work done on the system)
Therefore, the change in internal energy is

The value of the equivalent resistance for the three resistors connected in series will be the sum of the three values.
To find the answer, we have to know more about the equivalent resistance.
<h3>What is meant by equivalent resistance?</h3>- equivalent resistance is the total value of the resistance connected in a circuit.
- If n resistors are connected in series, then the equivalent resistance will be,
- In our question we have three resistors. Thus, the equivalent resistance will be,
Thus, we can conclude that, the value of the equivalent resistance for the three resistors connected in series will be the sum of the three values.
