Potential energy is turned in to kinetic and kinetic I believe is being used in motion. potential means stored kentic means energy of movement.
I believe that the answer is A. Decaying
These 2 isotopes are all of bromine that is naturally found (their percentages add up to 100%). In order to calculate the mean atomic mass, we can use the following calculation:
. This yields an average atomic mass of 79.903 amu. This procedure is general; whenever we have many types F of a specific genre G, the mean of the genre G can be calculated by:
where
is the proportion of type i in the genre G. In this example, Br79 and Br81 are the 2 types and the genre is Bromine.
Answer:
The answer is D.
Explanation:
Hold the styrofoam ball at arm's length from the eye.
Sodium chloride is readily soluble in water and insoluble or only slightly soluble in most other liquids. It forms small, transparent, colorless to white cubic crystals. Sodium chloride is odorless but has a characteristic taste. It is an ionic compound, being made up of equal numbers of positively charged sodium and negatively charged chloride ions<span>. When it is melted or dissolved in water the ions can move about freely, so that dissolved or molten sodium chloride is a conductor of electricity; it can be decomposed into sodium and chlorine by passing an electrical current through it </span>
