Euro 1.2379 0.8078
Mexican Peso 0.0752 13.2993
Swiss Franc 1.0299 0.9710
Chilean Peso 0.002071 482.80
New Zealand Dollar 0.8083 1.2371

Required:

a.
a. If you have $280, how many Polish zlotys can you get?
b. How much is one euro worth in U. S. dollars? (Round your answer to 4 decimal places, e. g., 32.1616.)
c. If you have 4.60 million euros, how many dollars do you have? (Enter your answer in dollars, not millions of dollars, rounded to the nearest whole dollar amount, e. g., 1,234,567.)
d. Which is worth more, a New Zealand dollar or a Singapore dollar?

A. Z936.77

B. 1.2379

C.$5,694,340

D.​New Zealand dollar

Explanation:

a. Calculation to determine how many Polish zlotys can you get

Numbers of polish=$280(Z3.3456/$1)

Numbers of polish =Z936.77

Therefore the numbers of Polish zlotys that you can get is Z936.77

B. Based on the information given the worth of one euro in U.S. dollars is 1.2379

C. Calculation to determine how many dollars do you have

Dollars amount=€4,600,000($1.2379/€)

Dollars amount=$5,694,340

Therefore The amount of dollars you have is $5,694,340

D. Based on the information given NEW ZEALAND DOLLAR is worth more.

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.

correct, but each time you dont pay the price of the penalty can increase.
