Answer:
Kinetic energy is the energy in a moving object, such as a person that has already jumped. Potential energy means energy that could be used. A bouncy ball sitting on a shelf 5 ft from the ground has less potential energy than one sitting 10 ft from the ground. A person that is about to bungee jump has potential energy because they are not yet in motion.
The question is accompanied of a table showing the atomic masses and abundances of the five isotopes and asks to calculate the atomic mass of the element with five significant figures. You just have to add the products of the atomic mass of each isotope times its abundance and divide by 100. This is the calculation:<span>
(179.946706*0.12 + 181.948206*26.5 + 182.9502245*14.31 + 183.9509326*30.64 + 185.954362*28.43 ) / 100 = 183.84 (which is rounded to five significant figures)</span>
