The speed of light is around 3.000E5 km/s. It takes approximately 9.221 seconds for light reflected from the moon Vega to reach planet Xartan. What is the average distance from the moon Vega to the planet Xartan?

Explanation:

Speed

The speed is calculated as the ratio of the distance d by the time t:

If we need to calculate the distance, the equation is solved for d:

d=v*t

The speed of light is

It takes t=9.221 seconds for light reflected from the moon Vega to reach planet Xartan.

We can calculate the average distance the light traveled:

Or, in scientific notation:

overcharge is the right answer system

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
