Gravitational Potential Energy = mgh.
Where m = mass in kg.
g = acceleration due to gravity = 9.81 m/s2.
h = height in metres.
PE is in Joules
Potential Energy = 20 * 9.81*100 = 19620 J
Answer:
its a sure for not but i think its a 192583
The easiest way to answer this question is just to get the answer first. The answer is A with the added comment that no chemical reaction has taken place.
Layered means that the chemicals are not soluble in one another. B is not the answer.
C is eliminated by what what was said about A.
D a solution is not a pure substance (singular) by itself. There are at least 2 chemicals together.
