An airplane flies in a straight line between two cities that are separated by 840 kilometers. If it takes 4 hours for the airplane to make the trip, what is it

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

We put a force of 50n on an object and the acceleration is 100 m/s². what is the mass of the object?
