What is E-commerce?

What is E-commerce? E-commerce (Electronic commerce or EC) is the buying and selling of goods and services or transmitting funds or data over an electronic network, primarily the internet. These business transactions occur either business to business, business to consumer, consumer to consumer, or consumer to business. This thesis is concerned with the impact of electronic commerce on international tax laws, specifically source-based taxation. Before looking specifically at the arguments and propositions to be advanced by the thesis, it is both instructive and necessary, to begin with, a discussion of what is meant by ‘electronic commerce’. Discussions relating to electronic commerce normally begin with a pronouncement that it represents a fundamental and revolutionary development in communications that is likely to dramatically change the way business is conducted. This is usually followed by highly variable, speculative, and often mind-numbing estimates of the expected growth of th

What is work?

If because force-displacement happens then the product of force and component of displacement at the direction of force due to force is work.

Work is the product of applied force on a body and its displacement along the direction of a force.

Unit of work: J (Joule)

Dimension of work, [W] = ML2T-2

What is Joule?

If due to the appliance of one-newton force at the direction of force the application point of force moves 1 meter then it is 1 joule of work.


What is positive work?

If due to force the application point of force moves along the direction of force or the component of displacement is towards the direction of force then it is said to be work done by force or positive work.

What is negative work?

If due to force the application point of force moves in the opposite direction of force or the component of displacement is at the opposite direction of force then it is said to be work done on force or negative work. 

What do you mean by the work 50 J?

The work measuring 50 J means 50 m of displacement of a body towards the direction of a force measuring 1 N. It further means 1 m of displacement of the body toward the direction of a force measuring 50 N.
