mash [69]

Answer:

4000 km

1) How is the temperature of a gas related to the kinetic energy of its particles?
dlinn [17]
The average kinetic energy of a gas particle is directly proportional to thetemperature. An increase intemperature increases the speed in which the gas molecules move. Allgases at a given temperature have the same average kinetic energy. Lightergas molecules move faster than heavier molecules.

Describe how pieces of rope move as waves pass
MaRussiya [10]
Well, as the waves move it moves the rope as if its trying to take shape of it. Since the rope it light it will move along the ocean and the ocean will keep pushing up on the rope. (even without the waves the water is pushing the rope up so it can take its shape)
