ECONOMICS- Exchange Rate
Suppose an economy under fixed (pegged) exchange rates is currently facing:
(i) a balanced current account (NX = 0),
(ii) a negative output gap (excess unemployment), and
(iii) a balanced budget.
(a) Using an NX/ (S-I) model depict the above situation in relation to the internal and external balance diagrammatically.

(b) Now suppose as an advisor to the government your recommendation is to employ an expenditure-changing policy to attain the Internal Balance. Explain in details what this policy is made up and what the consequences of your recommendations will be. Show diagrammatically and explain fully.

(c) In light of your answer to part (b) would you agree with this statement? “A trade deficit and low savings go hand in hand.” Evaluate fully.

(d) Defend this proposition “attaining the two policy objectives of internal and external balance requires two polices”. Explain and illustrate diagrammatically.

C. A business plan is a business’s roadmap for the future.

Explanation:

We are given 4 statements and we have to chose the correct statement. Let's analyze these statement one by one.

A. Businesses do not need to document a business plan.

Every business whether small or large must create a business plan. In fact, one of the most important thing for a business to be successful is its detailed business plan which must cover all the important aspects of the business e.g. pricing, revenue model, customer demographics etc. Therefore, option A is NOT a correct statement

B. Established businesses do not create a business plan.

It is equally important for an established business to have a business plan as it is for a startup. Business plan is a vision of the future. If a established business has a well defined business plan, chances of their success and chances of them achieving their goals will be significantly more. Therefore, option B is NOT a correct statement

C. A business plan is a business’s roadmap for the future.

This a true statement. Business plan is termed as a blueprint of success for the business. This means, a business plan lists all the ways, methods by which a business will sale its services/products and achieve its goals set for the future. Therefore, option C is a correct statement.

D. A business plan guarantees a business’s success.

It is true that a well formulated business plan increases chances of success, but it does not guarantee success. This is because there are many other factors for determining the success, one of which is execution of the business plan and ideas. If the business plan is not properly executed, it will be of no use. Therefore, option D is NOT a correct statement.

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.
