Where are NIST's primary locations?

The name for the upward or downward movement of an aircraft

As the temperature of a thermal radiator is increased Group of answer choices the object appears redder. the object appears bluer. the object emits more power for the same area. the object emits less power for the same area.

A piston-cylinder assembly contains a two-phase liquid-vapor mixture of H20 at 220 lbf/in^2 with a quality of 75%. The mixture is heated and expands at constant pressure until a final temperature of 475°F is reached.

The line voltage of a balanced three-phase transmission line is 4200 V rms. The transmission line has an impedance of 4 6 Z j l    per phase. Assuming that the load receives a total of 1 MVA at 0.

A heat pump with refrigerant-134a as the working fluid is used to keep a space at 25°C by absorbing heat from geothermal water that enters the evaporator at 60°C at a rate of 0.415 kg/s and leaves at 40°C.

Work done by a system during a process can be considered as a property of the system. a) True b) False

When the compression process is non-quasi-equilibrium, the molecules before the piston face cannot escape fast enough, forming a high-pressure region in front of the piston. It takes more work to move the piston against this high-pressure region.

hypothetical A-B alloy of composition 40 wt% B-60 wt% A at some temperature is found to consist of mass fractions of 0.66 and 0.34 for the α and β phases, respectively.
