The relationship between the pressure p and volume v of the air in a cylinder during the upstroke of a piston in an air compressor can be expressed as pvk = c where k and c are constants. during a compression test, the following data are taken: p (mm hg) 760.0 1160 1540 2285 3060 3810 v (cm3) 70.4 52.8 43.6 33.3 27.3 23.6 we wish to determine the values of k and c (both numerical values and units) that best fit the data.

okay i have so many questions. but the big one here is: um wt..f is this mess? ?

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.
