When the energy of a stimulus falls below the absolute threshold, its presence cannot be detected. true or false?

Truck traveling west on the highway experiences an acceleration to the east. what could be the cause of this acceleration

Agas initially at p1 = 1 bar and occupying a volume of 0.5 liter is compressed within a piston–cylinder assembly to a final pressure p2 = 4 bar. (a) if the relationship between pressure and volume during the compression is pv = constant, determine the volume, in liters, at a pressure of 3 bar. (b) repeat for a linear pressure–volume relationship between the same end states. reference
