Consider four objects ,A, B,C,and D. It is found that A and B are in thermal equilibrium. It is also found that C and D are in thermal equilibrium. However, A and C are not in thermal equilibrium. One can conclude that(A) B and D are in thermal equilibrium.(B) B and D could be in thermal equilibrium, but might not be.(C) B and D cannot be in thermal equilibrium.(D) the zeroth law of thermodynamics does not apply here, because there are more than three objects.

A block of mass m1=3.0kg rests on a frictionless horizontal surface. A second block of m2=2.0kg hangs from an ideal cord of negligible mass that runs over an ideal pulley and then is connected to the first block . the blocks are released from rest . determine the displacement of the velocity of the first block 1.2 s after the release of the blocks, assuming the first block doesn't run out of the room on the table and the second block doesn't land on the floor? A) 23.5m/s B) 12m/s C) 33.7m/s D) 6.7m/s
