Fpenny's piston is wider than pauly's, who is pushing with greater force?

It would depend on who is stronger but it is likely that Penny would be creating larger pressure because the surface area is less. If this is part of a question where the pressure for both is the same then Pauly is pushing with greater force, I know this because force/area=pressure and when the surface area is larger the force must be greater as well.

Hope this helps :)

1) when you rub your hands together quickly, the kinetic energy is converted to mechanical energy.2) thermal energy from the sun travels to earth as infrared waves.3) energy is transferred through the matter of space by electromagnetic waves. 4) when a match is burned, chemical potential energy is converted to thermal and radiant energy. 5) seismicwaves are caused by back and forth movement , or vibration, of an object. 6) mechanicalenergy in an engine changes thermal energy into kinetic energy to make a car move.
