An air-standard dual cycle has a compression ratio of 9. at the beginning of compression the pressure is 100 kpa, the temperature is 300k while the volume is 14 liters. the heat addition is 22.7 kj, with one-half added at constant volume and one-half added at constant pressure. using exact analysis determine; a) sketch the cycle on a p - v and t- s diagrams b) the temperatures at the end of each heat addition process, in k c) the net work of the cycle, per unit mass of air, in kj/kg. d) the thermal efficiency. e) the mean effective pressure, in kpa.

wavelength divides in half and speed stays the same.

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.
