Aphysics student in a hot air balloon ascends vertically at constant speed. consider the following four forces that arise in this situation:
f1 = the weight of the hot air balloon f3 = the force of the student pulling on the earth
f2 = the weight of the student f4 = the force of the hot air balloon pulling on the student
which two forces form an "action-reaction" pair that obeys newton's third law?

The scalar triple product computes the magnitude m of the moment of a force vector f about a specified line. it is m = (r ร f) ยท n, where r is the position vector from the line to the point of application of the force and n is a unit vector in the direction of the line. use matlab to compute the magnitude m for the case where f = [12, โ5, 4] n, r = [โ3, 5, 2] m, and n = [6, 5, โ7].

Arigid tank is divided into two equal parts by a partition. one part of the tank contains 3 kg of compressed liquid water at 400 kpa and 60ยฐc while the other part is evacuated. the partition is now removed, and the water expands to fill the entire tank. determine the entropy change of water during this process, if the final pressure in the tank is 40 kpa. use steam tables.
