Answer:
an artificial body placed in orbit around the earth or moon or another planet in order to collect information or for communication.
Explanation:
Look it up on google
Answer:
v = 10 m/s
Explanation:
recall that velocity is related to wavelength and frequency by the formula
v = fλ
where v = velocity, f = frequency and λ= wavelength
Simply substitute these into the formula:
v = fλ
v = (0.5)(20)
v = 10 m/s
The answer is 59.4 degrees.
Your gas mileage would be 22.93 miles per gallon.
The frequency of a wave becomes higher due to the object moving at a fast pace coming towards you with shorter wavelengths (depending on the speed) aka the Doppler Effect.
Hope this helps
