100 POINTS Three teams are involved in a 3-way tug of war. team 2 is able to exert a force of 700N south. The middle hoop where all of the ropes are connected is moving at 3.5m/s2 to the west from team three force. Team 1 is pulling 30 degrees above the horizontal. What is the force exerted by teams q1 and 3. ANSWER RIGHT NOT STUPgID ANSWERS OKLD

Zirconium has an hcp crystal structure and a density of 6.51 g/cm3. (a) what is the volume of its unit cell in m3? (b) if the c/a ratio is 1.593, compute the values of c and a.

Arod of some material 0.20 m long elongates 0.20 mm on heating from 21 to 120°c. determine the value of the linear coefficient of thermal expansion [in (degrees c)^-1] for this material.

Air initially at 0.75 bar, 1000 k, and occupying a volume of 0.12 m^3 undergoes two processes. process 1-2: the air is compressed isothermally until the volume is halved. process 2-3: the air undergoes a constant pressure process until the volume is halved again. assume ideal gas behavior. a) determine the mass of the air, in kg. b) the work and the heat transfer for each of the two processes, in kj. (100 kj = 1 bar . m^3)
