When comparing pike or tuck dives: is it true or false to say that both body positions have a differential effect on the diver’s angular acceleration (around the diver’s m-l axis)? provide concise reasons/arguments to support your answer

When at a point two solid phase changes to one solid phase on cooling then it is known as a) eutectoid point b) eutectic point c) peritectic point d) peritectoid point

Refrigerant 134a enters an insulated compressor operating at steady state as saturated vapor at -26°c with a volumetric flow rate of 0.18 m3/s. refrigerant exits at 9 bar, 70°c. changes in kinetic and potential energy from inlet to exit can be ignored. determine the volumetric flow rate at the exit, in m3/s, and the compressor power, in kw.

The higher the astm grain size number, the finer the gran is. a)-true b)-false
