A diver has 3,400 J of gravitational potential energy after climbing
up onto a diving platform that is 6.0 m above the water. What is
the diver's mass in kilograms?

Diver's mass in kilograms is 57.8kg.

Given:

Gravitational potential energy= 3,400 J

Height, h=6.0 m

Gravitational potential energy:

Gravitational potential energy can be given as:

where, m= mass, g= gravitational field and h= height

To find diver's mass, substitute the values in the above formula:

Diver's mass in kilograms is 57.8kg.

Explanation:

Potential energy is given by:

Where U is potential energy, m is mass, g is acceleration due to gravity, and h is height. Using this equation:

we need the questions , i may then you.

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
