A diver who weighs 500 N steps off a diving board that is 10 m above the water. The diver hits the water with kinetic energy of 8) A) 10 J. B) 500 J. C) 5000 J. D) more than 5000 J. E) 510 J.

C) 5000 J

Explanation:

when diver is at some height , he is having some energy in the form of potential energy. when he dives, his potential energy is converted into kinetic energy . so kinetic energy and potential energy are equal.

Kinetic energy of diver = potential energy of diver

= mgh

= 500 x 10

= 5000 J .

graph slopes whilst gas cools, then it is flat whilst conensation to liquid happens, the coolong liquid then graphs as a slope when it solidifies graph is flat
