Business Fundamentals was developed by the Global Text Project, which is working to create open-content electronictextbooks that are freely available on the website http://globaltext.terry.uga.edu. Distribution is also possible viapaper, CD, DVD, and via this collaboration, through Connexions. The goal is to make textbooks available to the manywho cannot afford them.

Supply chain management is the business function that coordinates and manages all the activities of the supply chain, including suppliers of raw materials, components and services, transportation providers, internal departments, and information systems. [link] illustrates a supply chain for providing packaged milk to consumers.

A supply chain. Supplier A goes to lathing, grinding, assembly, and painting, before finishing at shipping. Supplier B goes to milling, drilling, painting, and assembly, before also finishing at shipping.
Illustration of a supply chain

In the manufacturing sector, supply chain management addresses the movement of goods through the supply chain from the supplier to the manufacturer, to wholesalers or warehouse distribution centers, to retailers and finally to the consumer. For example, Apple, Inc uses sophisticated information systems to accept orders for custom-built computers from individual customers all over the world. Apple assembles the computers in Shanghai, China, to the customers’ specifications. It uses parts and components that are provided by outside suppliers who can deliver the right parts in the right quantity in a timely way to satisfy the immediate production schedule. The completed computers are flown from Shanghai by FedEx, reaching the end-user customers only a few days after the orders were placed. Apple’s supply chain allows it to provide fast delivery of high-quality custom computers at competitive prices.

Supply chain concepts also apply to the service sector, where service firms must coordinate equipment, materials, and human resources to provide services to their customers in a timely manner. For example, a retail store that sells electronic products may contract with an outside business to provide installation services to its customers. In many cases, the customer does not even know the installation was done by an outside contractor. Information and communication technologies such as global positioning systems (GPS), barcode technology, customer relationship management (CRM) databases, and the Internet allow service businesses to coordinate external and internal service suppliers to efficiently and effectively respond to customer demand.

The supply chain is not just a one way process that runs from raw materials to the end customer. Although goods tend to flow this way, important data such as forecasts, inventory status, shipping schedules, and sales data are examples of information that is constantly being conveyed to different links in the supply chain. Money also tends to flow “upstream” in the supply chain so goods and service providers can be paid.

Questions & Answers

Three charges q_{1}=+3\mu C, q_{2}=+6\mu C and q_{3}=+8\mu C are located at (2,0)m (0,0)m and (0,3) coordinates respectively. Find the magnitude and direction acted upon q_{2} by the two other charges.Draw the correct graphical illustration of the problem above showing the direction of all forces.
Kate Reply
To solve this problem, we need to first find the net force acting on charge q_{2}. The magnitude of the force exerted by q_{1} on q_{2} is given by F=\frac{kq_{1}q_{2}}{r^{2}} where k is the Coulomb constant, q_{1} and q_{2} are the charges of the particles, and r is the distance between them.

what is a capacitor?
Raymond Reply
Capacitor is a separation of opposite charges using an insulator of very small dimension between them. Capacitor is used for allowing an AC (alternating current) to pass while a DC (direct current) is blocked.

which has a higher temperature, 1cup of boiling water or 1teapot of boiling water which can transfer more heat 1cup of boiling water or 1 teapot of boiling water explain your . answer
Ramon Reply
I believe temperature being an intensive property does not change for any amount of boiling water whereas heat being an extensive property changes with amount/size of the system.
Someone
Scratch that
Someone
temperature for any amount of water to boil at ntp is 100⁰C (it is a state function and and intensive property) and it depends both will give same amount of heat because the surface available for heat transfer is greater in case of the kettle as well as the heat stored in it but if you talk.....
Someone
about the amount of heat stored in the system then in that case since the mass of water in the kettle is greater so more energy is required to raise the temperature b/c more molecules of water are present in the kettle
Someone
definitely of physics

Two bodies attract each other electrically. Do they both have to be charged? Answer the same question if the bodies repel one another.
JALLAH Reply
No. According to Isac Newtons law. this two bodies maybe you and the wall beside you. Attracting depends on the mass och each body and distance between them.

Are you really asking if two bodies have to be charged to be influenced by Coulombs Law?

What is specific heat capacity
Destiny Reply
Specific heat capacity is a measure of the amount of energy required to raise the temperature of a substance by one degree Celsius (or Kelvin). It is measured in Joules per kilogram per degree Celsius (J/kg°C).
