Where does a goverment's power come from?

Popular sovereignty means that the people rule "we the people", as it says in the declaration of independence. The people help vote government officials and help influence government decisions.

This is what i found on google “the first mobile phone call was made 40 years ago today. on april 3, 1973, motorola employee martin cooper stood in midtown manhattan and placed a call to the headquarters of bell labs in new jersey.” i hope this you for what your looking.
