Luigi minimized the stress of testing positive for HIV by viewing this circumstance as an opportunity for a renewed religious commitment and spiritual growth. His reaction best illustrates the importance of

His reaction best illustrates the importance of stress appraisal.

Explanation:

Stress appraisal explains how the individuals handle and cope with the stressful event. The individuals are monitored and evaluated on how they handle the situation or event. The reaction of the people may differ on how they understand the happening.

The person undergoing stress may be emotional and the outcomes of the person depend on the level of the stress he/she is undergoing. The person with stress may feel tensed, angry and frustrated.

His reaction best illustrates the importance of Stress Appraisal

Explanation:

Stress Appraisal refers to the technique by which individuals evaluate their stress and try to cope up with the stress

Stress appraisal refers to the evaluation of the event that causes stress

From the above question we can see that Luigi is trying to minimized his stress by  diverting himself towards religious and spiritual commitments.

sound is invisible, but sometimes we can feel it. when a kettle-drum is thumped with a stick that time the tight drum skin moving up and down very quickly for some time and then it pumped sound waves into the air. loudspeakers also work in a similar manner.

components of a speaker:

electromagnet

in order to translate an electrical signal into an audible sound, an electromagnet is used in looudspeakers

  suspension

suspension is used to   center the voice coil in the gap of the magnet and it exerts a restoring force to keep it there. suspension is used to limits the maximum mechanical excursion of the diaphragm and voice coil.

voice coil

voice coil is a coil of wire which is attached to the apex of a loudspeaker cone. it provides the motive force to the cone by the reaction of a magnetic field to the current passing through it.

cone

in a   loudspeaker, a   thin, semi-rigid membrane attached to the voice coil, which moves in a magnetic gap due to which it vibrates   and produced sound. it is known as diaphragm and it can also be called a cone, though not all speaker diaphragms are cone-shaped.

surround

surround is also known as front suspension. surround is used to join the cone to the chassis. together with the suspension it controls the cone excursion, and it is also used to   determine how energy which is   travelling through the cone is absorbed, and how the speaker limits when it reaches the ends of its travel.

dustcap

dustcap is used to protect the voice coil from dust and dirt. it is a part of the cone.

how speaker work

the outer part of the cone is fastened to the outer part of the loudspeaker's circular metal rim. the inner part is fixed to   voice coil that sits just in front of a permanent magnet . when loudspeaker is hooked up to a stereo, electrical signals feed through the speaker cables into the coil. it will convert the coil into an electromagnet magnet . when electricity flows back and forth in the cables, the electromagnet either repels or attract the permanent magnet. this moves the coil back and forth, and it pull and push the loudspeaker cone. like a drum skin vibrating back and forth, the moving cone pumps sounds out into the air.in this way loudspeakers works.
