General internal energy expression:
Uf = (Ui-W) + Q
Where Uf = Final internal energy, Ui = Initial internal energy, W = Work done, Q = Heat added
But,
Uf -Ui = ΔU = 36 J, W = 17 J. Then,
ΔU = -W +Q => Q = ΔU+W = 36+17 = 53 J
Therefore, heat added to the system is 53 Joules

Light-dependent reaction of photosynthesis
Answer:
5 N
Explanation:
Given that,
A large bar magnet of mass 0.4 kg exerts a 5 N force on a small bar magnet (mass of 0.1 kg) located 20 cm away.
We need to find the force exerted by the small bar magnet on the large one.
We know that, every action has an equal and opposite reaction. Both action and reaction occur in pairs. The force acting on one object to another is same and in opposite direction on the other object.
Hence, the force exerted by the small bar magnet on the large one is also 5 N.
