The Chain Rule is a formula for computing the derivative of the composition of two or more functions. For instance, if <i>f </i>and <i>g </i>are functions, then the chain rule expresses the derivative of their composition.
The Chain Rule Formula is as follows –
dy/dx = dy/du . du/dx

Energy is a conserved quantity and the law of conservation of energy states that energy can neither be created nor destroyed but can only be converted from one form to another. The SI unit of energy is Joule.

Each base quantity is defined in terms of a certain basic arbitrarily chosenbut properly standardised reference standard called unit (such as metre,kilogram,second,ampere,kelvin,mole,and candela.The units for the fundamental base quantities are called fundamental or base units and two supplementary units in relation to quantities plane angle and solid angle radian, Ste radian..
Supplementary units are the dimensionless units that are used along with the base units to form derived units in the International system. The class of supplementary contains only two purely geometrical units, that is the radian and the steradian.The supplementary unit of plane angle is radian and that of solid angle is steradian.

A calliper is a device used to measure the distance between two opposing sides of an object. It can be as simple as a compass with inward or outward-facing points. First the tips of the calliper are adjusted to fit across the points to be measured and the calliper is then removed and the distance between the tips is measured using a ruler.
The modern Vernier calliper was invented by Joseph R. Brown in 1851. It was the first practical tool for exact measurements that could be sold at an affordable price to ordinary machinists. The Vernier Calliper consists of a main scale fitted with a jaw at one end. Another jaw, containing the vernier scale, moves over the main scale. When the two jaws are in contact, the zero of the main scale and the zero of the Vernier scale should coincide. If both the zeros do not coincide, there will be a positive or negative zero error.
Parts of a Vernier Caliper
1.Main Scale
The main scale consists of a steel metallic strip graduated in centimeters at one edge and in inches at the other edge . It carries the inner and outer measuring jaws. When the two jaws are in contact, the zero of the main scale and the zero of the Vernier scale should coincide. If both the zeros do not coincide, there will be a positive or negative zero error.

Let AB be tower.
BC be original shadow.
BD be final shadow.
Given BD-BC = CD = 50m
∴ In ΔABC,
tan 60° = AB/BC
=> AB/√3 = BC ...(1)
∴ In ΔABD,
tan 30° = AB/BD
=> 1/√3 = AB/(BC+CD)
=> AB√3 = AB/√3+50 (From 1)
=> AB√3-AB/√3 = 50
=> 3AB-AB/√3 = 50
=> AB = 50√3/2 = 25√3 = 25*1.732 = 43.30m

- Gravitational Force: It is the force of mutual attraction between any two objects by virtue of their masses. It is a universal force as every object experiences this force due to every other object in the universe.
- Electromagnetic Force: It is the force between charged particles. Charges at rest have electric attraction (between unlike charges) and repulsion (between like charges). Charges in motion produce magnetic force. Together they are called Electromagnetic Force.

Reductionismare identical to, or are collections or combinations of, entities of another (often simpler or more basic) kind or that expressions denoting such entities are definable in terms of expressions denoting other entities. Thus, the ideas that physical bodies are collections of atoms or that a given mental state (e.g., one person’s belief that snow is white) is identical to a particular physical state (the firing of certain neurons in that person’s brain) are examples of reductionism.
Unification: It is the act of unifying the different laws valid for different phenomena in to a single theory that explains all the different phenomena. Eg. ... These are unified under theory of electromagnetism; Reduction: It is the effort to solve a complex problem by breaking it into simpler parts.

Significant figures are the number of digits in a value, often a measurement, that contribute to the degree of accuracy of the value. We start counting significant figures at the first non-zero digit. Calculate the number of significant figures for an assortment of numbers. For example, 91 has two significant figures (9 and 1), while 123.45 has five significant figures (1, 2, 3, 4 and 5). Zeros appearing anywhere between two significant figures are significant: 101.1203 has seven significant figures: 1, 0, 1, 1, 2, 0 and 3.
