Mrs. Mechinus wants to determine which type of ball has the highest bounce. She drops a tennis ball, soccer ball, then a basketball from a height of 15 feet, and measures & records how high each bounces back up. Identify the dependent and independent variables in this experiment. Use supporting details to explain why they are those variables. Please help

im pretty sure its b

catya that's not even a b or c

they are all solids.

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
