Explain what the ionosphere is and how it interacts with some radio waves.

Explained

Explanation:

Ionosphere is the outermost layer of the Earth's atmosphere,extending from 60 km to 1,000 km altitude.It mainly consists of ionized gases by the solar radiation.It is very important layer to Earth because it influences the radio propagation to distant places on Earth. Being ionized it reflects high frequency(shortwave) radio waves to the sky as well as to the Earth by a technique called "skip" or "skywave" propagation for the communication over long distances.

F  you double the  force, you double the acceleration, but  if  you double the  mass, you velocity. all bodies accelerate at the  same  rate regardless of size or  mass.
