Answer:
a. the amount of work done on a system is dependent of pathway
Explanation:
The first law of thermodynamics states that the change in internal energy of a system equals the net heat transfer into the system minus the net work done by the system.
ΔU = Q - W
Where;
Q, the net heat transfer into the system depends on the pathway
W, the net work done by the system also depends on the pathway
But, ΔU, the change in internal energy is independent of pathway
Therefore, the correct option is "A"
a. the amount of work done on a system is dependent of pathway
Answer: the velocity is zero at the following points
1. At the highest point in the oscillation.
2. At the lowest point in the oscillation.
Explanation:
Explanation:
Many would know it as a reaction force. Reaction force is the force by the surface on the object perpendicular to it's motion. So if we apply force on the sliding block perpendicular to it's direction of motion, friction will increase. ... That force is proportional to the velocity with which it is moving.
