Simple harmonic motion can be represented as the projection of uniform circular motion onto a diameter of the circular path.
Efficiency is the ratio of useful output energy or work to input energy or work. Real devices have efficiency below 100% because some input energy becomes…
Polymers: Polymers are large molecules built from many smaller repeating units called monomers. Monomers: Monomers are small molecules that bond…
KOH aqueous, heat: substitution favoured. KOH alcoholic, heat: elimination to alkene favoured (school contrast). Same KOH, different solvent story. SN means…
A hexagon is cyclohexane if no double bonds drawn as in benzene (benzene is a special ring later). Empirical from % composition (stoichiometry chapter). Trap:…
Adding a Video Clip in Website: To add a video clip in a website, the `<video>` tag is used where you can define the clip size and how the clip should be…
Control of Harmful Bacteria: Control of harmful bacteria refers to the use of chemical and physical methods to inhibit the growth of bacteria or kill them.…
Identity p(x)=(x-c)q(x)+R. At x=c the first piece dies. R is constant because the divisor is degree 1. That is the whole theorem.
Bioelectricity refers to electrical potentials and currents produced by the movement and distribution of ions in living systems. Bioelectricity is…
For rigid-body rotation, linear and angular quantities are linked by the radius: s = rθ, v = rω, at = rα, and ac = rω².
Exponential growth occurs under abundant resources; logistic growth slows near carrying capacity as limiting factors intensify.
Importance of Diffusion Rates in Medicine: The study of how quickly drug molecules spread from the site of administration to the bloodstream and target…
Solar Radiation is the energy emitted by the Sun in the form of electromagnetic waves, including visible light, ultraviolet (UV) radiation, and infrared…
Chapter 12 also names probability with statistics: a probability is a number from 0 to 1. Compound events use 'and' / 'or' with diagrams (tree, Venn) as listed…
A large randomly mating population without mutation, migration or selection keeps allele frequencies constant; deviations help identify evolutionary forces.
Typical tasks: n!, nPr, nCr, circular (n-1)!, together/not together, committee with restrictions. First decide: does order matter? Line vs circle? Then write…
The mean-square speed is the average of the squares of molecular speeds: ⟨c²⟩ The root-mean-square speed is: crms = √⟨c²⟩
Carbohydrates are organic biomolecules composed of carbon, hydrogen, and oxygen in a 1:2:1 ratio, with the general formula Cₓ(H₂O)ᵧ. They are the major source…
The main idea is that benzene has a highly stable delocalized pi (π) electron ring which remains intact in most reactions. Benzene shows different…
Entropy Change (ΔS°): The difference between the standard entropies of the products and the standard entropies of the reactants.
xfrac2a2-yfrac2b2=1 has c2=a2+b2 and foci (+-c,0).
Isomerism: Phenomenon in which compounds have the same molecular formula but they differ in structural arrangement or formula is called isomerism.…
Two points A and B on a circle cut two arcs: the minor (shorter, less than a semicircle) and the major (the long way). A semicircle is half the circumference,…
An LED (Light-Emitting Diode) emits light when forward current flows. It is polarized and usually needs a series resistor to limit current.
