An oxygen molecule is moving near the earth's surface. another oxygen molecule is moving in the ionosphere (the uppermost part of the earth's atmosphere) where the kelvin temperature is three times greater. determine the ratio of the translational rms speed in the ionosphere to the translational rms near the earth's surface.'

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.

electromagnetic shielding is the practice of reducing the electromagnetic field in a space by blocking the field with barriers made of conductive or magnetic materials. shielding is typically applied to enclosures to isolate electrical devices from their surroundings, and to cables to isolate wires from the environment through which the cable runs. electromagnetic shielding that blocks radio frequency electromagnetic radiation is also known as rf shielding.

the shielding can reduce the coupling of radio waves, electromagnetic fields and electrostatic fields. a conductive enclosure used to block electrostatic fields is also known as a faraday cage. the amount of reduction depends very much upon the material used, its thickness, the size of the shielded volume and the frequency of the fields of interest and the size, shape and orientation of apertures in a shield to an incident electromagnetic
