Answer: B. It demonstrates a behavior or particles.
Explanation: I took the test and got it right
If the coefficient alpha for a stress scale was computed to be 0.80, the scale would be strongly reliable. A coefficient alpha that is at least 0.70 and above is considered to have a strong internal consistency, which means the items in the scale are closely related as a group.
the answer to the question is (D)
Answer:
option C
Explanation:
given,
energy dissipated by the system to the surrounding = 12 J
Work done on the system = 28 J
change in internal energy of the system
Δ U = Q - W
system losses energy = - 12 J
work done = -28 J
Δ U = Q - W
Δ U = -12 -(-28)
Δ U = 16 J
hence, the correct answer is option C
