An object's motion changes A.
when the forces acting on the object remain balanced.
B.
only when a nonzero net force is applied to the object.
C.
only if the object is at rest when a force acts upon it.
D.
when there are no forces acting upon it.

The correct answer is:
B. only when a nonzero net force is applied to the object.

Explanation:
A net force is the sum of the unbalanced forces acting on an object. An object's motion changes only when a nonzero net force is applied to the object. When a nonzero net force is applied to an object, the object's speed and/or direction changes.

If the forces acting on the object are balanced, they will cancel each other out and will not cause the motion of the object to change.

answer : (a) volume of the gas = 8.67 ×   l

                (b) second virial coefficient b = -1.21226 l/mole

solution :   given,     t = 300k

                                p = 20atm

                                z = 0.86

                                n = 8.2 mmoles = 8.2 × moles

                                r =   0.082 l atm/k/mol

        find,     (a) volume of gas   and (b) second virial coefficient b at 300k.

formula used :            

                          and            

(a)            

                    = \times 0.082\times 300}{20}[/tex]

                    = 8.67 ×   l

(b)      

                    = (0.00867-1) × 8.659

                    = - 8.5839 l/mole
