<u>Answer</u>:
Cell phones contain rechargeable batteries that transform chemical energy into electrical energy. When using your cell phone, electrical energy is first transformed into <u>Electromagnetic waves </u>that are transmitted through the air.
<u>Explanation</u>:
When chemical energy is converted into electrical energy in cell phones, then this electrical energy firstly transformed or converted into electromagnetic waves which travels through air. Then this electromagnetic wave is converted into sound energy due to which users are able to listen audio, music, movies etc on their mobile phones.
The electrochemical energy that stored in a cell is removed as electrical energy in the process of discharging. There are so many other thermal and electrochemical processes taking place at the same time.
The kinetic energy of a large vehicle is greater than the kinetic energy of a small vehicle, so the stopping distance for the larger vehicle would also be greater.

The total number of unemployed people is the statistic.
Explanation:
The number of unemployed people is defined by the number of people who do not have a job but are actively seeking employment.
This also has a filter on the total population against the age limit below which it is not legally permissible to work.
So, considering all these filters have been met in the description of the statistic mentioned in the question it is easy to assume that this statistic is about the total number of people who are unemployed in an area or a country.
<span>Geography is an area of science that includes the earth’s
surface or lands, phenomenon, features, and the biology of our ancestors or
inhabitants in the form of fossils. Geography as a study deals more on
landforms, rivers, mountains, coastlines, and the like. Thus, land bridges were
pretty much a constant topic among geographers since the land bridges were very
significant in terms of historical earth formation. </span>
