Answer:
The energy of a body or a system with respect to the motion of the body or of the particles in the system. Potential energy is the stored energy in an object or system because of its position or configuration. Kinetic energy of an object is relative to other moving and stationary objects in its immediate environment.

Answer:
69.7231 u to 4 decimal places.
Explanation:
Gallium is composed of two natural occuring isotopes that is Ga-69(60.108%) with mass of 68.9256 amu and Ga-71(39.892%) with mas of 70.9247 amu. The ratio of their masses are 1.0290. The relative abundance of Ga-69 is 60.11% and Ga-71 is 39.89%.
Calculate average atomic mass of Ga-69 :
Ga-69 = 60.108% = 0.60108.
GA-71 = 39.892% = 0.39892.
Atomic mass of Ga = (68.9256⋅0.60108)+(70.9247⋅0.39892)
AM(Ga)=69.7231 u to 4 decimal places.
