Amplitude is the maximum displacement from equilibrium; larger amplitude generally means more wave energy.
Neutral Equilibrium is a state in which a body, when displaced from its original position, stays in its new position. It neither returns to its original…
Geothermal energy is thermal energy obtained from Earth's interior.
A Loudspeaker (or speaker) is an electroacoustic transducer that converts electrical audio signals into sound. It uses the interaction between a permanent…
Cloud Computing: Cloud Computing refers to delivery of computing services over the Internet by cloud computing vendors. These services include servers,…
xfrac2a2-yfrac2b2=1 has c2=a2+b2 and foci (+-c,0).
The group number of an element in the periodic table can provide information about the charge of an ion formed by an element. Simple explanation: If…
Trade-offs between Usability and Security refer to the compromises that must be made when designing systems, where improving one factor (usability or…
A catalyst is a substance that accelerates a chemical reaction but remains chemically unchanged at the end of the reaction. The phenomenon is…
Parallel nonvertical lines have equal slopes; perpendicular slopes multiply to -1.
A vernier caliper is a measuring device used to measure a fraction of the smallest division on a main scale by sliding another scale over it. It can be…
System Diagram (SD): A visual expression of all the objects required in a given situation. It shows the objects and their interactions. Free-Body Diagram…
You can place an unknown element accurately at the appropriate position in the periodic table, and can predict its properties. Simple explanation: If…
Water conservation (“use less”) means using freshwater efficiently and reducing unnecessary losses while still meeting legitimate human, agricultural,…
For y'+P(x)y=Q(x), integrating factor is e^(integral P dx).
Effects of Smoking: The effects of smoking on the respiratory system are the harmful changes and diseases caused by inhaling cigarette smoke. These include…
A homogeneous mixture (a solution, such as brine) cannot be sorted by eye. A heterogeneous mixture (sand in water) shows separate parts. The method you pick…
Energy enters mainly as sunlight and is lost as heat at each transfer. Consequently higher trophic levels support less energy and usually less biomass.
Carbohydrates are organic compounds that serve as a major source of chemical energy for living organisms.
For a cubic x^3 + b x^2 + c x + d = 0 with roots p,q,r (monic): p+q+r = -b, pq+qr+rp = c, pqr = -d. For ax^3+... divide through by a first, or use the general…
The main idea is that the increasing reactivity of Group 2 metals down the group is evident in their reactions with oxygen, water, and dilute acids. The…
Fluid Friction is the retarding force that a fluid (liquid or gas) exerts on an object moving through it. The moving body exerts a force on the fluid to…
Scalability refers to the ability of a network to handle growing amounts of work or to be easily expanded. Reliability refers to the ability of a network to…
Doping produces N-type (electron majority) and P-type (hole majority) semiconductors. Joining them forms a P-N junction used in diodes and other devices.
