Which skier will have a greater potential energy? justify your answer. skier 1 will have more potential energy because he is higher than skier 2 skier 2 will have more potential energy because he will go faster than skier 1. both skiers will have the same amount of potential energy since they both weigh the same.

Skier 1 will have more potential energy because he is higher than skier 2

Explanation: Gravitational potential energy is the energy possessed by a body by virtue of its position or height.

P.E=

m= mass of the body

g= acceleration due to gravity

h= height of body

Thus if the masses of two bodies are same, the one with greater height possess greater potential energy.

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

i belive it is water
