The winds of the recent hurricanes in florida are bringing significant financial gain to california orange growers. due to the extensive damage to the florida orange crop, many oranges were destroyed. the ones remaining were just as good as the previous oranges. california oranges are commanding their highest prices ever." if florida and california oranges are substitute goods, which of the following statements best explains the economics of the quotation? a. the demand for florida oranges has been reduced, causing their prices to fall and therefore increasing the demand for the substitute california orangesb. the supply of florida oranges has decreased, causing the supply of california oranges to increase and their prices to risec. the demand for florida oranges has been reduced by the hurricanes, causing a greater demand for the california oranges and an increase in their priced. the supply of florida oranges has decreased, causing their price to increase and the demand for the california oranges to increase also

The correct answer is option d.

Explanation:

Unfavorable weather in Florida has adversely affected the production of Florida oranges. The decline in production has led to reduced supply of Florida oranges. This decrease in supply will lead to an increase in the price.  

As Florida oranges and California oranges are substitutes, with the increase in the price of Florida oranges will lead to an increase in the demand for California oranges as people will prefer the cheaper substitute.

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.
