Diamonds were formed over 3 billion years ago deep within the Earth's crust under conditions of intense heat and pressure that cause carbon atoms to crystallise forming diamonds. This expansion causes the magma to erupt, forcing it to the Earth's surface and taking along with it diamond bearing rocks.

The medulla oblongata helps regulate breathing, heart and blood vessel function, digestion, sneezing, and swallowing. This part of the brain is a center for respiration and circulation.Besides the medulla oblongata, your brainstem also has a structure called the pons. The pons is a major structure in the upper part of your brainstem. It is involved in the control of breathing, communication between different parts of the brain, and sensations such as hearing, taste, and balance.

The vertices of the triangle ΔABC are A (1, 2), B (- 3, 2) and C (3, - 2). The sides of the triangle are AB, BC, CA and we have to find the tangent ratio of the angle A.
The slope of the line AB is
m₁ = (2 - 2) / (- 3 - 1)
= 0 and
that of the line CA is
m₂ = (2 + 2) / (1 - 3)
= - 2
Then the angle A is determined from
tanA = (m₁ - m₂) / (1 + m₁m₂)
= (0 + 2) / (1 + 0)
= 2
Hence tanA = 2

| Sl. No. | Differentiating Property | Resistance | Resistivity |
| 1 | Definition | Resistance is the physical property of a substance because of which it opposes the flow of current i.e. electrons. | Resistivity is the physical property of a particular substance which is having particular dimensions. |
| 2 | Proportionality | Resistance is directly proportional to the length and temperature while it is inversely proportional to the cross-sectional area of the material. | Resistivity is only proportional to the nature and temperature of the particular material. |
| 3 | Symbol | R | ρ |
| 4 | Formula | R = V/I or, R = ρ(L/A) V = Voltage, I = Current, ρ = Resistivity |
ρ = (R×A)/L
R = Resistance, L= Length, A = Cross-sectional area |
| 5 | SI Units | The SI unit of resistance is Ohms | The SI unit of resistivity is Ohms-meter. |

The pressure required to prevent solvent from passing through a semipermeable membrane from a region of higher concentration of solute to a region of lower concentration of solute is called osmotic pressure. It is also a measure of the tendency of a solution to gain water by osmosis when separated by a membrane from pure water.
