Why is a database a tertiary source? Indexes, bibliographies, concordances, and databases may not provide much textual information, but as aggregates of primary and secondary sources, they are often considered tertiary sources. However, they may also provide access to the full text or content of primary and secondary sources. What are some examples of tertiary […]

What is the first step in any design process? Discovery is the first step of the design process, where teams work together to develop an understanding of the problem they are trying to solve, and define the path they will take to explore solutions. It culminates in the communication of a vision – a concise […]

What happens if a hot air balloon lands in your yard? As a general rule, pilot or crew chef are supposed to ask the property owner if it is OK to land on private property and take the balloon down. If they did not ask, they are basically trespassing. Trespassing pilot and crew may harm […]

How do genes influence traits? Genes (say: jeenz) play an important role in determining physical traits — how we look —and lots of other stuff about us. They carry information that makes you who you are and what you look like: curly or straight hair, long or short legs, even how you might smile or […]

How many atoms are in FCC? four atoms What are 111 planes? The symbol (111) represents Miller indices for an infinite set of parallel planes, with intercepts 1, 1 & 1 along the three crystallographic axis (unit lattice parameter along these), which pass through lattice points. On what planes of a bcc structure can the […]

What does increase in demand mean? An increase in demand means that consumers plan to purchase more of the good at each possible price. c. A decrease in demand is depicted as a leftward shift of the demand curve. d. A decrease in demand means that consumers plan to purchase less of the good at […]

What is the magnetic field in the center of the solenoid? For the first part, since the solenoid is long we can approximate the magnetic field inside to be uniform and is given by Bz=μ0NI, so we can say that the magnetic field at the center is also μ0NI. What is the ferrite core used […]

Do airplanes have constant velocity? Since there is no net external force on the aircraft, the aircraft will maintain a constant airspeed as described by Newton’s First Law of Motion. However, if the forces become unbalanced, the aircraft will move in the direction of the greater force. How is an aircraft held into a turn? […]
