Aseismograph has a heavy weight that is hung from a spring. what would happen if the weight were attached to a rod instead of a spring? the weight would not oscillate. the weight would oscillate. the pen would not make contact with the paper. the seismograph would not be accurate. the seismograph would not function. you can choose more than one. i think it's the first one and the last one but i'm not sure. i'm also not sure what subject this would be under so excuse me if i choose the wrong one.

1 is the answer to this problem

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
