Suppose that a worker in Radioland can produce either 4 radios or 1 television per year, and a worker in Teeveeland can produce either 2 radios or 4 televisions per year. Each nation has 100 workers. Also suppose that each country completely specializes in producing the good in which it has a comparative advantage. If Radioland trades 100 radios to Teeveeland in exchange for 100 televisions each year, then each country's maximum consumption of new radios and televisions per year will be

300 radios, 100 televisions in Radioland and 100 radios, 300 televisions in Teeveeland

Explanation:

This question has been answered by in two parts

1. Radioland

Each worker can produce either 4 radios or 1 television

The country has a total of 100 workers

Radioland specializes in radio production because it has comparative advantage in this good, therefore Radioland will only produce radios.

Therefore, the total number of radios it will produce per year

= 4 radios per worker * 100 workers

= 400 radios.

If Radioland trades 100 radios to Teeveeland in exchange for 100 televisions each year, Radioland will end up with

= 400 radios - 100 radios (to Teeveeland) + 100 televisions (from Teeveeland)

= 300 radios + 100 televisions in Radioland.

2. Teeveeland

Each worker can produce either 2 radios or 4 televisions

The country has a total of 100 workers

Teeveeland specializes in television production because it has comparative advantage in this good, therefore teeveeland will only produce television.

Therefore, the total number of televisions it will produce per year

= 4 televisions per worker * 100 workers

= 400 televisions.

If Teeveeland trades 100 televisions to Radioland in exchange for 100 radios each year, Teeveeland will end up with

= 400 televisions - 100 televisions (to Radioland) + 100 radios (from Radioland)

= 300 televisions + 100 radios in Teeveeland.

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.
