Suppose First Main Street Bank, Second Republic Bank, and Third Fidelity Bank all have zero excess reserves. The required reserve ratio is 20%. The Federal Reserve buys a government bond worth $1,500,000 from Manuel, a customer of First Main Street Bank. He deposits the money into his checking account at First Main Street Bank. Complete the following table to reflect any changes in First Main Street Bank's T-account.
Assets Liabilities
Reserves/deposits/net work/loan Reserves/deposits/net work/loans
Complete the following table to show the effect of a new deposit on excess and required reserves when the required reserve ratio is 20%.
Hint: If the change is negative, be sure to enter the value as negative number.

Now, suppose First Main Street Bank loans out all of its new excess reserves to Latasha, who immediately uses the funds to write a check to Jake. Jake deposits the funds immediately into his checking account at Second Republic Bank. Then Second Republic Bank lends out all of its new excess reserves to Nick, who writes a check to Rosa, who deposits the money into her account at Third Fidelity Bank. Third Fidelity lends out all of its new excess reserves to Alyssa as well.
Fill in the following table to show the effect of this ongoing chain of events at each bank.

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.
