Answer:
The ratio of the translational rms speed in the ionosphere to the translational rms near the earth's surface is
Explanation:
The relation between the translational rms speed and the temperature is given by :
So,
When the temperature is three times greater.
The ratio of the translational rms speed in the ionosphere to the translational rms near the earth's surface is :
Hence, this is the required solution.
Question:
A high ____will have a short wavelength
Answer:
That means that waves with a high frequency have a short wavelength, while waves with a low frequency have a longer wavelength. Light waves have very, very short wavelengths
Explanation:
Hope it help
Answer:
Explanation:
PE = mgh
g = PE/mh
g = 15.0 / (0.200(0.500))
g = 150 m/s²
This is one strong astronaut if he can work in an environment where gravity is more than 15 times stronger than on earth.
