Modulus Of Elasticity Of Mass Rock Is Usually ? A) Less Than Rock Substance
B) Equal To Rock Substance
C) Higher Than Rock Substance
D) Not Correlated To Rock Subsrance

The Correct answer is A) or B)

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.

Two technicians are discussing the intake air temperature (iat) sensor. technician a says that the computer uses the iat sensor as a backup to the engine coolant temperature (ect) sensor. technician b says that the powertrain control module (pcm) will subtract the calculated amount of fuel if the air measures hot. who is correct

The mass flow rate of the fluid remains constant in all steady flow process. a)- true b)- false
