Teaching profession is a 'mission', rather than a job. A teacher may not find the affirmation of his/her career choice in salary, administrators or even the students whom he/she teaches, but he/she must believe in the uncanny ability of a good teacher to positively impact the future and to leave lasting, indelible marks on those who will one day be the leaders in all facets of society. It is this power in the hands of a teacher that translates to big responsibility. A teacher who realises these things is on a mission to empower, enable and to make a positive difference.

Given from figure angle of incidence i=600
angle of refraction r=30⁰
We know μ= sin i​/sin r
μ= sin60/sin30 ​=((√3)/2) ​​×2=√3

P = I² R = (10)² × 5 = 500 watt = 0.5 kW

t = 30 minute = 0.5 hr

E = P × t = 0.5 kW × 0.5 hr = 0.25 kWh

In Fleming’s left-hand rule the thumb indicates the direction of mechanical force acting on the conductor. The forefinger points in the direction of magnetic field and the central finger in the direction of current flowing in the conductor.

Vector- A physical quantity having a magnitude as well as direction is known as vector quantity. 
Odometer - an instrument for measuring the distance travelled by a wheeled vehicle. 
Acceleration of a body is defined as the rate of change of its velocity with time. 
Scalar - A physical quantity having only magnitude is known as a scalar quantity.

If we get a curve line in the displacement – time graph, it means that the velocity of the object is changing over time. The velocity is not constant but varies at different points on the curve.

A curve in the displacement – time graph indicates that the object is undergoing acceleration, which in turn means that the velocity is changing. The shape of the curve can provide information about the nature of the change in velocity.

There are different cases when we can have a curve in the displacement – time graph:

• Increasing velocity: If the curve is upward sloping, it means that the velocity is increasing with time.


• Decreasing velocity: If the curve is downward sloping, it means that the velocity is decreasing with time.


• Changing acceleration: If the curve has varying slopes, it means that the acceleration is changing, and therefore, the velocity is also changing.

Therefore, if we get a curve line in the displacement – time graph, the velocity is non-uniform, as it is changing over time. Option B is the correct answer.

The wavelength is the distance between two consecutive crest or trough in case of transverse wave. Here, distance between consecutive crest and trough is x, so, wavelength will be 2x.

Mendeleev's Periodic Law states that the properties of elements are the periodic function of their relative atomic masses. Mendeleev arranged all 63 elements; which were discovered till his time; in the order of their increasing relative atomic masses in a tabular form. It is known as Mendeleev's Periodic Table.

Representative elements in modern periodic table
The first two groups on the extreme left and last six groups on the extreme right involve the filling of s- and p- orbitals, respectively, These groups represent the main groups of the periodic table and are numbered as 1, 2, 13, 14, 15, 16, 17 and 18. The elements present in these groups are known as normal elements or representative elements.

Mass of common salt (solute) = 40g
Mass of water (soluted) = 320g
Mass of solution = 320 + 40 = 360g
Concentration of solution = M(mass of solute) / mass of solution = 40/360 x 100 = 11.11%

Changes of state are physical changes in matter. They are reversible changes that do not involve changes in matter’s chemical makeup or chemical properties. Common changes of state include melting, freezing, sublimation, deposition, condensation, and vaporization.

Acid convert blue litmus solution to Red. HCHO, CH₃CHO are aldehydes. HCOOH, CH₃COOH are carboxylic acids. CH₃OH and C₂H₅OH are alcohols. Out of these only carboxyhc acids would turn blue litmus solution red. So HCOOH and CH₃COOH would turn blue litmus solution red.

For the correction, option B has to be: The main ingredient of biogas is methane. It burns without smoke and leaves no residue.

Green manure is a term used to describe crops or plants which are grown for the purpose of manuring the soil. Green manure crops are grown, cut and ploughed in the soil to enhance the soil fertility. Green manuring is an eco-friendly method of manuring the soil. Examples of green manure crops include sunhemp, dhaincha etc.

Respiration rates may increase with fever, illness, and other medical conditions. When checking respiration, it is important to also note whether a person has any difficulty breathing. Normal respiration rates for an adult person at rest range from 12 to 16 breaths per minute.

Recycling requires energy. Reuse means using the same thing again and again.

Cartilage is not found in kidney. As cartilage is a structural component  of our body act as connective tissue which  is not required in the kidney. They are flexible connective tissue mainly found in ribs, ear, nose  etc.

Insinuate means suggest or hint (something bad) in an indirect and unpleasant way
Some insinuate that he doesn't love India enough to defend it wholeheartedly
It's degrading for people like Romney to insinuate that they don't contribute
