Electromagnetic waves can carry more data at higher frequencies. why would a scientist opt to transmit data at a lower frequency instead

A scientist opt to transmit data at a lower frequency instead because lower frequencies transmit data farther. Using reliable internet sources, identify three ways we use analog and digital signals in our everyday lives.

a plasma is a warm ionized gasoline consisting of approximately equal numbers of definitely charged ions and negatively charged electrons. the characteristics of plasmas are notably unique from the ones of ordinary neutral gases in order that plasmas are considered a awesome "fourth kingdom of remember."

when [oh-] is 10-5  m, and [h3o+] is 10-9  m, the poh is 5 and ph is 9. again in both cases the sum of ph and poh is 14. however, the hydrogen ion concentration is not always going to be equal to exactly 1 x 10 raised to a negative number. for example, we skipped over the value of 2.0 x 10-7.
