If the sun is just on the horizon behind you, other drivers looking in your direction will have a difficult time seeing you. You can help enable other drivers to see you better if you...Turn your headlights on.
Airborne Refraction.
The sun is lowering slightly above the horizon as we watch. The atmosphere that surrounds our planet is what causes this intriguing occurrence. Without an atmosphere, the sun would set directly on the horizon.
A layer of air roughly 100 kilometers thick surrounds our planet. As you ascend vertically, this atmosphere becomes less dense. Also keep in mind that air has a refractive index that is slightly higher than that of the vacuum.
The sun's beams now experience a minor bending owing to refraction as they strike the top layers of the atmosphere. As the rays enter the lower atmosphere with a higher optical density, the bending keeps becoming worse.

This type of refusal is known as a strike.
Answer:
A researcher recreates a sociological study to establish reliability of the findings.
Explanation:
A sociological study that wishes to probe the findings, will be supported with empirical evidence.
Empirical pieces of evidence are facts that are backed up by the experience.
It means that this knowledge is a product of direct and indirect work, and it involves experience in the process.
Empirical research cannot be biased. It is evidence that comes from actual knowledge gained through experience rather mere beliefs or information.
Empirical evidence will help to uncover details to questions that are significative in the research of a problem.
Explanation:
This is because static charges (negative) develop when nylon clothes are rubbed. Then nylon comes in contact with the hair on your skin and it develops opposite charge as of the hair on your skin. The crackles are because of the static electricity.
