1 point A horizontal force accelerates a box from rest across a horizontal surface
(friction is present) at a constant rate. The experiment is repeated, and all
conditions remain the same with the exception that the horizontal force is
doubled. What happens to the box's acceleration? *
It increases to more than double its original value.
It increases to exactly double its original value.
It increases to less than double its original value.
It increases somewhat.

Air is contained in a variable-load piston-cylinder device equipped with a paddle wheel. initially, air is at 400 kpa and 17°c. the paddle wheel is now turned by an external electric motor until 75 kj/kg of work has been transferred to air. during this process, heat is transferred to maintain a constant air temperature while allowing the gas volume to triple. calculate the required amount of heat transfer in kj/kg.

Two steel balls, each of mass m, are welded to a light rod of length l and negligible mass and are initially at rest on a smooth horizontal surface. a horizontal force of magnitude f is suddenly applied to the rod as shown. determine (a) the instantaneous acceleration a of the mass center g and (b) the corresponding rate at which the angular velocity of the assembly about g is changing with time.
