2. Demand terminology Complete the following table by selecting the term that matches each definition.

Definition

Quantity Demanded= The claim that, with other things being equal, the quantity demanded of a good falls when the price of that good rises

Demand Curve= A graphical object showing the relationship between the price of a good and the amount of the good that buyers are willing and able to purchase at various prices

Demand Schedule = A table showing the relationship between the price of a good and the amount that buyers are willing and able to purchase at various prices

Law of Demand = The amount of a good that buyers are willing and able to purchase at a given price

Apply your understanding of the previous key terms by completing the following scenario with the appropriate terminology.

Your coworker Bob is really concerned about a project that he has just been assigned. He is in charge of analyzing and determining conditions in the market for televisions from an extensive sales report.

If Bob's boss is interested in a graphical representation of the relationship between the price and quantity of televisions demanded, you would advise your coworker to construct a ( demand curve) using the data provided. However, if Bob's boss is more interested in the detailed numbers used to construct this visual representation, you would instead advise your coworker that a ( Demand schedule) would be more appropriate

going on the gulag might you to find a better answer for that problem

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.
