g A system begins at pressure p0 and volume V0. The volume is held constant and a quantity Q1 of heat is added to the system, which increases the pressure to 2p0. A second quantity Q2 is added to the system as it expands at pressure 2p0 to a new volume 2V0. Determine the net change in internal energy of the system. Express your answer in terms of the variables Q1, Q2, p0, and V0.

force is based upon mass and acceleration.the statement is not always true.

it can be explained from newton's second law of motion.

as per newton's second law of motion the rate of change of momentum is directly proportional to the applied force and takes place along the direction of force.

mathematically it can be written as -

                                              ⇒      

here   k is the proportionality constant whose value is 1.

                                                            [a is the acceleration=dv/dt]

hence we see that force not only depends on mass and acceleration but also on velocity and rate of change of mass. force f will depend on mass and acceleration only when mass is constant.

hence the statement that force is based upon mass and acceleration is false.
