People exert a downward force (their weight) when sitting in a chair. Why do people not fall through chairs due to this force?
Group of answer choices

because the force of the person is less than the weight of the chair

Because Newton's First Law of Inertia

Because the mass of the chair is greater than the mass of the person

Because the chair exerts an equal and opposite force on the person

Because the chair exerts an equal and opposite force on the person

Explanation:

Usually, for every action force, there is an equivalent reaction force exerted in the opposite direction to the action force. This is known as the Third Newton Law. This is the same principle that is behind rockets. The ejection of hot exhaust released by the burning of fuel of the rocket (action force) causes an equivalent reaction force that propels the rocket forward in the opposite direction of the ejection of the exhaust gases.

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
