What is the power, in Watts, needed to lift 15-N box 1.5 meters up in 5.0 seconds?

ASAP PLS

Amass of 1.5 kg of air at 120 kpa and 24°c is contained in a gas-tight, frictionless piston-cylinder device. the air is now compressed to a final pressure of 720 kpa. during the process, heat is transferred from the air such that the temperature inside the cylinder remains constant. calculate the boundary work input during this process.

What precautions should you take to prevent injuries when dealing with heavy loads?

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