A18000 kg truck is driving along a level road with a velocity of 32 m/s. if the driver suddenly applies the brakes for 12 seconds so that the truck's velocity reduces to 16 m/s. find the coefficient of kinetic friction between the tires and the surface of the road.

On a average work day more than work place firs are reorted

The temperature of air decreases as it is compressed by an adiabatic compressor. a)- true b)- false

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.
