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…
Same carbons: ox/redox, add/elim, sub. Extra carbon: nitrile from CN- then hydrolyse. Never invent a Grignard unless the book taught it (name only if so). Ask:…
If a polynomial is quadratic in a block, set y equal to that block. A common Class 9 choice is y = ax^2 + bx (sometimes plus a constant). Then an expression in…
SOURCE VERIFICATION STATUS: The canonical label “Numbers” is ambiguous. The inventory does not specify which numerical values Topic “Numbers” should teach. Do…
A few identities save time in every paper. logb 1 = 0 because b0 = 1. logb b = 1 because b^1 = b. For matching base and argument power, log_a (a^x) = x (the…
Transportation through blood is the process by which blood carries digested food, oxygen, carbon dioxide, excretory waste, hormones, and heat to and from…
Filtration separates by particle size. The residue is the solid left on the filter. The filtrate is the liquid that goes through. Gravity filtration uses…
VSEPR Theory: Valence Shell Electron Pair Repulsion Theory — a model used to predict the shape of molecules based on the repulsion between electron pairs…
The brain requires a continuous supply of energy and nutrients because its cells remain metabolically active even during sleep.
Molecular Formula A molecular formula shows the number of atoms of each element in a molecule. Simple explanation: The molecular formula tells…
Product law: log(mn) = log m + log n. Quotient law: log(m/n) = log m - log n. Power law: log(m^k) = k log m. They follow from the index laws, because a…
OP = [x, y] if P is (x, y). It locates P. Two different points have different position vectors.
A chaotic system is a deterministic nonlinear system that can be highly sensitive to small differences in initial conditions.
A speed-time graph is a plot of speed (on the vertical y-axis) against time (on the horizontal x-axis). It shows how the speed of an object changes over…
Sub-Atomic Particles: The particles that make up an atom — electrons, protons, and neutrons.
Acceleration is a=dv/dt=d^2s/dt^2 and does not by itself tell the direction of motion.
The following are the uses of cloud computing: File Storage File storage is the most common use of cloud computing. A cloud-based storage system enables…
SI has seven base units. They are independent: none is made from the others. Derived units are made by combining base units. Lab work often prefers g and cm3,…
Rated a little above the normal current of the appliance, not far above. In the live wire so the appliance goes dead when it blows. A 13 A fuse in a table lamp…
Two observers, same height object, two elevations: write tan for each and subtract distances if they are on the same line. Name the right triangles before you…
Analogue signals vary continuously; digital signals use discrete levels such as binary 0 and 1. ADC converts analogue to digital; DAC converts digital to…
Dark, dull surfaces are generally good absorbers and emitters of thermal radiation.
|xi + yj| = sqrt(x^2 + y^2), Pythagoras. |3i-4j|=5. |-5i+12j|=13. |0|=0. Magnitude is never negative. Equal vectors have equal magnitudes, but equal magnitudes…
The main idea is that while crossing the first-row transition metals, there is not as much similarity in chemical properties as we found in physical…
