Answer:117.6joules
Explanation:
Mass(m)=2kg
Height(h)=6m
Acceleration due to gravity(g)=9.8m/s^2
Potential energy(PE)=?
PE=m x g x h
PE=2 x 9.8 x 6
PE=117.6joules
All of the Noble Gases, which are on the right side of the periodic table, have a full outer energy level. The elements that are Noble Gases are the following: <span>Neon Argon Krypton Xenon Radon Ununoctium.
