TerraLoc competes in the market for global positioning devices and services. The company manufactures its own GPS units, which are smaller than those of any other competitor and include a proprietary battery that lasts 200% longer than any other competitor's battery and that TerraLoc manufacturers on-site. TerraLoc also has developed proprietary software that is much faster and more precise than that of any competitor. When developing the proprietary battery, TerraLoc decided to manufacturer the battery in-house to reduce the possibility that the company it outsourced the battery manufacturing to might reverse engineer the battery and sell a similar product to competitors. This possibility was especially troubling given that the company expected a significant increase in demand due to the improved battery life. Additionally, TerraLoc sells its products and services through its own direct sales force to ensure that its representatives highlight the longer battery life of TerraLoc's units. TerraLoc's decsion to manufacture the battery in-house is most consistent with which theory(s) of vertical integration?

a. Firm capability-based explanations
b. Alliance-based explanation
c. Opportunism-based explanations
d. Flexibility-based explanations

The correct answer is the option A: firm capability-based explanations.

Explanation:

To begin with, given the fact that the company decided to manufactured the battery in-house in order to reduce the possibility of helping other competitors when using an outsourced manufacturer then the company is using its firm capability in order to achieve the goal of manufacturing that component of the final product. Therefore that if the company would not have the resources and capability of doing it then it would necessary outsourced the manufactured of it.

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.

the correct answer is:

it required the president to inform congress within forty-eight hours of any new troop commitment.

the war powers resolution (1973) is a federal law designed to limit the u.s. president’s ability to initiate or intensify military actions abroad without the approval of the congress.

it establishes that the president can send armed forces into action abroad only by declaration of war by congress, statutory authorization, or in case of a national emergency created by attack upon the united states, its territories or possessions, or its armed forces.

it requires the president to notify congress within 48 hours of sending armed forces to military action.
