UK mains: Peak voltage(320V) while RMS is(240 V)
High voltages require less current to move more power
Ideal solutions: ions in solutions dont interact with each other
If there are interactions and that is non-ideal, departure from my
deal is quantified
weight of the fish = buoyant force of the water
Ideal fluid: incompressible, No internal friction, zero viscosity
Fluid element: smallest volume of fluid that follows general flow
Flow rate: Q = V/t, Can be related to velocity and cross-sectional
area of
Long sightedness: use a controverting lens to correct
Spherical aberration: lens doesnt bring all the light to focus at one
point
Chromatic: because different wavelengths refract differently, solve
use compound lenses, problem absorbs a lot of light

Populations
Population is an abstract concept because it is impossible to sample the
entire population
Consists of all the individuals, example all the healthy adults
Sample: collect data from a random sample, has a size (sample size)
Often denoted by and

Statistics
Scientists could collect data to test ideas of how the natural world works
Two types of data: descriptive and inferential
What is data?
Information collection from observational or experiment
Different wavelengths refry differently, total internal reflection:
maximum incident angle
Rainbows calls but rip fraction and reflection within water droplets
Light has electric and magnetic field that oscillates perpendicular to
the direction of propag
What is the probability of the number deviated from chance alone
Expectation: hypothesis, no hypothesis: all numbers already will in all
categories
1. Hypothesis: roll all numbers equally
2. Significance level, Ill but equals 0.05
3. Test chi-squared tes
Mechanics
Scalar: quantity completely described by magnitude (example 3 kg)
Vector: quantity which has both the magnitude and direction
Breaking factors into components, vertical and horizontal
Constant velocity: no acceleration, ignore air resistance
Fal
Range: difference between smallest and largest values since sensitive to
extreme values
IQR: split down into four quarters, is upper quartile lower quartile
Standard deviation: most common, denoted as S
Remember the 68-95-99.7 rule
Mean, median, mode are
Has conjugated double bonds, chlorophyll B has been one more
double bond
Allows for absorption a different wavelengths
Carotenoids: conjugated double bonds, accessory pigments
Can be separated by Crowell paper chromatography
Carotenoids go farthest do tw
