A carbon dioxide cylinder at a pressure of 540 kPa and a temperature of -3°C is delivered to a restaurant. What is the pressure inside the cylinder (in atmospheres) after it warms to room temperature 27°C ?

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.
