Answer:
Microwave takes 13.67μs to travel from cell phone to tower
Explanation:
Given data:
Distance traveled by microwave from cell phone to tower = [tex]\frac{4100 m}{3 x 10^{8} m/s}[/tex]
We know that the microwave is an electromagnetic wave and the velocity v of electromagnetic wave is 3 x [tex]10^{8}[/tex] m/s.
In general, to determine time of travel from distance and velocity given, we divide distance traveled by velocity. That is
Velocity = [tex]\frac{distance}{time}[/tex]
Hence, time = [tex]\frac{distance}{velocity}[/tex]
Therefore, time of travel of microwave = [tex]\frac{4100 m}{3 x 10^{8} m/s }[/tex]
= [tex]\frac{4100 m}{300 x 10^{6} m/s }[/tex]
= 13.67 x [tex]10^{-6}[/tex] s
= 13.67 μs (μs is microseconds)
Hence microwave takes 13.67μs to travel from cell phone to tower.
