Terminal Velocity. The speed with which an object moves (vertically) downward in a fluid when the resultant force acting on it is zero.

(2aii)
Viscosity is the property of a fluid which tends to prevent or oppose motion of one layer or part over another. It varies with the temperature and nature of the fluid

(2aiii)
Surface tension is the force per unit length acting in the surface at right angles to one side of a line drawn in the surface of a liquid.

(2bi)
Stoke's law states that the law that the force that retards a sphere moving through a viscous fluid is directly proportional to the velocity of the sphere, the radius of the sphere, and the viscosity of the fluid. the law that the frequency of luminescence induced by radiation is usually less than the frequency of the radiation.

(2bii)
Law of conservation of angular momentum states that in the absence of an external torque, the total angular momentum is conserved or the total angular momentum of an isolated system remains constant both in magnitude and direction.

(5ai) Electric flux is the measure of the electric field through a given surface, although an electric field in itself cannot flow. It is a way of describing the electric field strength at any distance from the charge causing the field.
The Electric flux is not affected by charges that are not within the closed surface.

(ii). Equipotential refers to a region in space where every point in it is at the same potential. This usually refers to a scalar potential, although it can also be applied to vector potentials.
An equipotential of a scalar potential function in n-dimensional space is typically an (n−1)dimensional space

(5bi) Resonance occurs in a RLC circuit when the total circuit current is “in-phase” with the supply voltage as the two reactive components cancel each other out.

Wants are the insatiable desire or need by human beings to own goods or services that give satisfaction. Human wants or needs are many and are usually described as insatiable because the means of satisfying them are limited or scarce.

(3b)
Scarcity is the limited supply of resources which are used for the satisfaction of unlimited wants. Scarcity is the inability of human beings to provide themselves with all the things they desire or want. These resources are scarce relative to their demand.

1ai) A gene is a basic unit of heredity and a sequence of nucleotides in DNA that encodes the synthesis of a gene product, either RNA or protein. During gene expression, the DNA is first copied into RNA. The RNA can be directly functional or be the intermediate template for a protein that performs a function.

ii)An allele is variant of a given gene. In genetics, genes normally exhibitdeviations or diversity: all alleles for a particular trait together make up the set of genetic information that defines a gene. For example, the ABO blood grouping is controlled by the ABO gene, which has six common alleles.

iii) A homozygous organism as related to genetics, refers to having inherited the same versions (alleles) of a genomic marker from each biological parent. Thus, an individual who is homozygous for a genomic marker has two identical versions of that marker.

iv)An organism that has the same two copies of a gene is considered homozygous for that trait, while an organism that has different copies of a gene for a particular trait is considered heterozygous for that trait.
