At the point where the ball stops it has speed of 0 m/s. When it continues to fall in every meter it gets 9.8 m/s so you just put this :
9.8 m/s2 x 2.5 m = 24.5 m/s
Answer:
Les changements d'état sont des changements physiques. Ils se produisent lorsque la matière absorbe ou perd de l'énergie. Les processus dans lesquels la matière change entre les états liquide et solide sont la congélation et la fusion. Les processus dans lesquels la matière change entre les états liquide et gazeux sont la vaporisation, l'évaporation et la condensation.

You probably already took this but if anyone wanted to know the answer it's D. "A system where matter and energy cannot enter or leave the system".
(I also took the quiz for it and got it correct)
Answer: Troposphere
Explanation:
Fairly over the "surface" of Uranus lies the troposphere, where the atmosphere is the densest. The temperature ranges from a minus 243 degrees Fahrenheit (minus 153 degrees Celsius) to minus 370 F (minus 218 C) , with the upper regions being the coldest. This makes the atmosphere of Uranus the coldest within the solar system. Inside the troposphere are layers of clouds — water clouds at the least weights, with ammonium hydro sulfide clouds over them. Alkali and hydrogen sulfide clouds come following. At long last, lean methane clouds lay on the best. The troposphere amplifies 30 miles (50 kilometers) from the surface of the planet.
Using this information, we can determine that the Troposphere is the densest layer of Uranus's atmosphere.
