The only vector quantity on that list is displacement.
Answer:
110.7 J
Explanation:
Hooke's law is represented by the formula:
F = ke where F is the force in Newton, K is force constant and e is extension in m
work done = 1/2ke² = 1/2 K ( e² - e₀²) and e₀ is the extension at relaxed length
e₀ =0
work done = 0.5 × 82N/m × (2.70 m)² = 110.7 J
Answer: False
Explanation:
The potential energy is called organized energy because it is not related to the mass movement of the molecules.
Heat is disorganized energy because it is related to the mass movement of the molecules. Entropy is related to the randomness of the molecules.
If the randomness of the system increases then the entropy will increase. The entropy of the system either remains constant or increases.
The entropy of the system never decreases.
Therefore, the answer will be false.
