Reasoning (according to Garrett): "Reasoning is a stepwise thinking with a purpose and goal in mind." It is a specialized form of thinking that enables a…
Generation and Transmission of Nerve Impulse: The generation and transmission of a nerve impulse refer to the sequence of electrochemical changes that…
Ionization Energy: The minimum amount of energy required to remove one mole of electrons from the isolated gaseous atom or ion. · First Ionization…
Polar Covalent Bond: A covalent bond in which the shared electrons are unequally distributed because of a difference in electronegativity between the…
The equation of continuity applies conservation of mass to steady fluid flow. Its general form is ρ₁A₁v₁ = ρ₂A₂v₂; for an incompressible fluid it becomes A₁v₁…
Disaccharides: Two monosaccharides combine to form a disaccharide. It is a kind of oligosaccharide. In simple words: A disaccharide is a sugar made of…
Electromagnetic waves are extremely useful, but some can be hazardous depending on frequency, intensity, exposure time and the body part exposed.
Minimum Viable Product (MVP) is the smallest version of a product that delivers core value to users and allows the team to learn from real customer feedback…
Strong Acid: An acid that ionizes completely in aqueous solution. Weak Acid: An acid that ionizes only partially in aqueous solution. Acid…
An arithmetico-geometric series mixes an AP with a GP, e.g. 1 + 2x + 3 x^2 + 4 x^3 + ... School: let S be the sum, form x S, subtract, then you get a GP you…
When a line is not vertical it can be written y=mx+c. Here m is the slope (gradient) and c is the y-intercept, the value of y where the line cuts the y-axis at…
Use class midpoints or given weights to calculate a representative average when raw values are not listed.
Rewrite f(x)=0 as x=g(x), choose a start, and compute x(n+1)=g(xn).
Ultraviolet (UV) radiation lies beyond violet light at higher frequency and shorter wavelength.
Need a matching side-angle pair to start. Angle sum 180 deg finds the third angle when two are known. SSA can give 0, 1, or 2 triangles (ambiguous case).
Energetics of Phase Changes: The study of energy changes (in the form of heat) that occur when a substance changes from one phase to another. Molar Heat…
Galvanic Cell (Voltaic Cell): The cell which involves a spontaneous redox reaction to generate electricity is called a galvanic or voltaic cell.…
Types of Operating Systems refer to the different categories or classifications of operating systems based on how they manage tasks, processes, users, and…
a + b cos(c theta + d): still [a-|b|, a+|b|]. Combined a sin theta + b cos theta = R sin(theta+alpha) with R=sqrt(a^2+b^2) if the book uses that rewrite (then…
Preparation by Titration: Preparation by titration is a method of preparing a soluble salt by reacting an acid with a soluble base (alkali) using exact…
The Cartesian plane is a grid made from two number lines that cross at right angles. A point is an ordered pair (x,y): x is the horizontal coordinate and y is…
Because electric potential is scalar, the total potential produced by several point charges is the algebraic sum of their individual potentials.
R=13, r=5: half-chord 12, chord 24. Same 5-12-13 triangle as chord-from-centre questions.
The energy stored in a capacitor is the electric potential energy required to separate charge onto its plates.
