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 are symptoms of timing being off? What causes ignition timing to be off? When any changes are made to the engine of a car, the ignition timing is adjusted accordingly. If not, you could experience several problems with your engine with improper ignition timing like knocking, hard to start, increase fuel usage, overheating, and […]

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 […]

What is the main difference between a radio wave and light? Both radio waves and light are electromagnetic waves; their main difference is their frequency. Radio waves are created by the acceleration of electrons in a radio antenna, and light waves are created by the oscillations of the electrons within atoms. How do you brighten […]

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 […]

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? […]

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 […]

How gravity affects walking up and down the stairs? 3 Answers. You have to lift up your body mass under the presence of gravity, so you have to overcome the force of gravity. While climbing up the stairs you have to put force on ground, more then your weight, which put same force but in […]

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 […]
