A full-wave rectifier converts both half-cycles of an AC input into a unidirectional output. Filtering reduces variations or ripple in the rectified…
Bio-mass refers to the material that provides bio-energy. It includes organic matter such as wood, agricultural residues, and animal waste. The energy…
Coal high CO2 per energy often. Methane less, but CH4 leak is itself a greenhouse gas (named). Trees as a slogan sink. Efficiency: useful energy / input. SO2…
Biology has three main divisions: Botany, Zoology, and Microbiology. By dividing biology into a number of sub- fields, its study becomes convenient. Each…
Alcohols and carbonyls often take the suffix. Halogens usually prefixes. If two functions, the book gives the priority (acid beats alcohol school).…
Interpretations of quantum mechanics are conceptual frameworks used to explain what the mathematical predictions of quantum theory may mean physically.
Wave Energy (or Ocean Wave Energy) is the energy obtained from the movement of surface waves on the ocean. It is a renewable energy resource that can be…
Two systems are in thermal equilibrium when they have the same temperature and no net heat flows between them. Thermodynamics describes a chosen system, its…
A charge q in an electric field E⃗ experiences force F⃗=qE⃗ and, if free, acceleration a⃗=qE⃗/m. A positive charge accelerates along the field while a negative…
Slipped Disc · Each intervertebral disc is a cushion like pad which consists of nucleus pulposus and annulus fibrosis. · Nucleus pulposus is…
The cell potential (Ecell) for a galvanic cell is literally the potential of the cell to do work on its surroundings by driving an electric…
Stoichiometry: The calculation of quantities of reactants and products involved in a chemical reaction using a balanced chemical equation. Mole Ratio:…
Memory Hierarchy: Computer memory is organized in a hierarchy, balancing speed, size, and cost. Faster memory types (Main Memory) are smaller and located…
Finite GP: Sn = a rn - 1r-1 if r != 1. If r=1, Sn = n a. If |r|<1 you can also write Sn = a 1-rn1-r (same thing). Meaning: factor a from a + a r…
Liver: The liver is the largest internal organ and the largest gland in the human body. It is a reddish-brown, wedge-shaped organ located in the upper…
Typical tasks: full induction (base+step); T_{r+1}; middle term; coefficient of x^k; two-term approximation. For induction, label Base, IH, Aim, then algebra.…
Colloid These are heterogeneous mixtures in which the solute particles are larger than those present in true solutions but not large enough to be…
NO2 acts as a catalyst in the oxidation of SO2 to sulphuric acid, thereby increasing the concentration of another strong acid in the atmosphere.…
Classification Based Upon Reaction Type: Enzymes are classified into six major groups based on the type of chemical reaction they catalyze. This system was…
Science, technology, and engineering do not work alone. In every real-life situation, they combine: · Science helps us understand the underlying…
(y-k)^2=4a(x-h) has vertex (h,k); translation does not change basic shape.
Nervous System: The system of the body that provides coordination through electric signals among different body parts for the response to a particular…
Move a conductor across a field and an emf appears (Faraday). Right-hand rule: Motion, Field, induced Current. Lenz: the induced current fights the change.…
