Two forces-55-N clockwise and 35-N counters clockwise-are applied to a merry- go-round with a diameter of 4.5 m. What is the net torque?
One mole of H 2 at 300 K takes a volume of 10 lits in a cylinder fitted with a piston. It is expanded isothermally to 20 lits. Consider ideal behavior for the gas, determine W, Q,
A mass of 6 kg lies on a smooth horizontal table, and is attached by a spring to a fixed point, as shown in the figure below. The spring has a stiffness of 375 N/m. (a). Determ
POSITIVE ACCELERATION: If velocity of a body is enhancing, then its acceleration is said to be positive. The direction of positive acceleration is similar as that of velocity.
