Velocity is calculated as 3 multiplied by (time (t) minus 5).

The change in kinetic energy equals the work done, calculated as 1/2 * mass * (final velocity^2 - initial velocity^2).

If energy (E) is constant, then momentum (P) is directly proportional to mass (m).

Radial acceleration is calculated as (velocity^2) / radius.

The fractional change in length (or deformation) of a material.

A constant in the equation relating force to deformation in an elastic material.

The number of spectral lines produced when an electron jumps from a higher energy level (n2) to a lower energy level (n1) is determined using the formula: (n2 - n1)(n2 - n1 + 1) / 2.

Butane (C4H10) has two structural isomers: n-butane (straight chain) and isobutane (branched chain).

Pentane (C5H12) has three structural isomers: n-pentane, isopentane, and neopentane.

All three given structures are isomers of benzene. They have the same molecular formula (C6H6) but different arrangements of atoms.

Concentration in parts per million (ppm) is calculated by dividing the mass of solute by the mass of solution, multiplied by 10^6.

22400 mL of CH4 at STP (Standard Temperature and Pressure) is equal to 1 mole of ROH.

The molecular mass of ROH can be calculated by dividing the mass of ROH by the number of moles of ROH.

The equation hc/λ = hc/λ1 + hc/λ2 is used to calculate the wavelength of light for a given spectral line.

The normal force acting on an object in an upward accelerating lift equals the weight (mg) plus the mass (m) times the acceleration (a) of the lift. N = mg + ma

The normal force acting on an object in a downward accelerating lift equals the weight (mg) minus the mass (m) times the acceleration (a) of the lift. N = mg - ma

By equating the normal force (N) in an upward and downward accelerating lift, we find that the acceleration (a) is equal to g/2, where g is the acceleration due to gravity.

The effective acceleration (a') acting on a rotating object is the difference between the centripetal acceleration (a) and the acceleration due to gravity (g). a' = a - g/2

When springs are connected in parallel, the reciprocal of the equivalent spring constant (k) equals the sum of the reciprocals of the individual spring constants (k1 and k2). 1/k = 1/k1 + 1/k2

The equivalent spring constant (k) represents the overall stiffness of a system of springs. It is calculated based on the individual spring constants and their arrangement.

The displacement (x) of a rotating object subjected to a force is calculated as 4a/g - 2a/g, where 'a' is the centripetal acceleration and 'g' is the acceleration due to gravity.

The centripetal acceleration (a) of a rotating object is calculated as the square of the velocity (v) divided by the radius (r) of the circular path. a = v^2 / r

A method of classifying organisms based on a large number of observable characteristics, often using computers to analyze data.

A branch of taxonomy that uses information about cells, such as chromosome number, structure, and behavior, to classify organisms.

A branch of taxonomy that classifies organisms based on the chemical constituents of their bodies.

The Golgi apparatus packages materials for delivery within the cell or export outside the cell.

Materials from the ER fuse with the cis face of the Golgi apparatus and move towards the trans face, where they are packaged and mature.

A division of plants that includes ferns, horsetails, and whisk ferns.

A division of plants that includes mosses, liverworts, and hornworts.

Algae contain pigments that capture light for photosynthesis, with different algae types having different dominant pigments.

The reactant that gets completely consumed first in a chemical reaction, limiting the amount of product formed.

A standardized system for naming chemical compounds, based on their structure, using specific prefixes and suffixes.

A measure of the disorder or randomness of a system. It increases with increasing disorder.

The sulphonic (-SO3H) group is given higher priority than other functional groups in IUPAC naming.

A molecule with chiral centers, but is achiral due to internal symmetry, resulting in identical configurations.

The net electrical charge of a molecule or ion, calculated by adding up the charges of all its atoms.

The velocity of an electron in a specific Bohr's orbit can be calculated using the formula: v = (2.18 × 10^6 m/s) * (Z/n), where Z is the atomic number and n is the principal quantum number.

The distance travelled by an electron in a specific Bohr's orbit can be calculated by multiplying its velocity by the time spent in that orbit.
