they arespaced the same as in air.
they areshifted upward.
they areshifted downward.

Agas contained within a piston-cylinder assembly undergoes three processes in series: process 12: compression with pv= constant from 1 bar and 1 liter to 4 bar. process 23: constant pressure expansion to 1 liter. process 31: constant volume calculate the pressure and volume at each state, and sketch the processes on a p-vdiagram labeled with pressure and volume values at each numbered stat

Suppose a comet has an orbital period of 309.1 years around the sun. what is it’s average distance from the sun?

When you hold a rectangular object, how does the area of the side that is resting on your hand affect the pressure and the force that the object exerts?
