Assume a telephone signal travels through a cable at two-thirds the speed of light. How long does it take the signal to get from New York City to Miami if the distance is approximately 1100 miles?

How many dollars per millisecond would the federal government have to collect to retire a deficit of $100 billion in one year?

If a signal can travel in a cable at 80% of the speed of light, what length of cable, in inches, represents 1 ns?

i = the current in volt

q = the charge in amperes,

t =. the time in seconds.
