Fertilizers are the inorganic compounds which supply specific nutrients.

For example: NPK (Nitrogen Phosphorous Potassium), ammonium sulphate, ammonium phosphate etc.

Lignite is a soft brown coal that still contains a high amount of water.

ADVANTAGES OF FRICTION
Friction plays a vital role in our daily life. Without friction we are handicap.
1. It is becomes difficult to walk on a slippery road due to low friction. When we move on ice, it becomes difficult to walk due to low friction of ice.
2. We can not fix nail in the wood or wall if there is no friction. It is friction which holds the nail.
3. A horse can not pull a cart unless friction furnishes him a secure Foothold.
4. We can write on a paper or on a board.
5. Friction helps in applying the brakes.
6. It helps in walking on floor.
7. Coffee mug stays on the dashboard.
8. Shuffling across a carpet to shock someone.
9. Draging of atmosphire with earth is possible
10. Helps to pevents the life on earth by burning astroids.
DISADVANTAGES OF FRICTION
Despite the fact that the friction is very important in our daily life, it also has some disadvantages like:
1. The main disadvantage of friction is that it produces heat in various parts of machines. In this way some useful energy is wasted as heat energy.
2. Due to friction we have to exert more power in machines.
3. It opposes the motion.
4. Due to friction, noise is also produced in machines.
5. Due to friction, engines of automobiles consume more fuel which is a money loss.
6. Machine efficency is decreased: energy input is lost to heat
7. Getting shocked by doorknobs
8. Rug burn
9. It counteracts movement and so it takes more energy to move, it can cause unwanted heat (e.g. in machine parts), and it wears things out like shoes.
10. Forest fires are caused due to friction between branches of trees

Organic farming is a farming system with minimal or no use of chemicals as fertilizers, herbicides, pesticides etc. and with a maximum input of organic manures, recycled farm-wastes, use of bio-agents such as culture of blue green algae in preparation of biofertilizers, neem leaves or turmeric specifically in grain storage as bio-pesticides, with healthy cropping systems [mixed cropping, inter-cropping and crop rotation. These cropping systems are beneficial in insect, pest and wheat control besides providing nutrients.

12 cm is  divided into 6 cm each, 16 cm is divided into 8 cm each

Step-by-step explanation: In the parallelogram, opposite sides are equal & parallel

Let say ABCD  is a parallelogram & Diagonals AC & BD intersect at O
Now comparing Δ AOB & ΔCOD
∠AOB = ∠COD  ( opposite angles)
∠ABO = ∠CDO  ( ad BD is cutting two ║ lines AB & CD)
Similarly ∠BAO = ∠DCO ( ad AC is cutting two ║ lines AB & CD)
So Δ AOB ≅ ΔCOD
AO/CO = BO/DO = AB/CD
AB = CD
=> AO/CO = BO/DO = 1
=> AO = CO    & BO = DO 
AO + CO = AC => AO = CO = AC/2
BO + DO = BD => BO = DO = BD/2

Hence Diagonals are bisected
Diagonal 12 cm is  divided into 6 cm each
Diagonal 16 cm is divided into 8 cm each

The Fundamental Rights

These are the basic human rights of all citizens, defined in Part III of the Constitution. These are applicable irrespective of race, place of birth, religion, caste, creed, or gender. They are enforceable by the courts, subject to specific restrictions. Following are some of the important rights of the citizens of India in accordance with the Constitution.

• Right to Equality
• Right to freedom
• Right against exploitation
• Right to freedom of religion
• Cultural and Educational Rights
• Right to Constitutional Remedies

A defendant is a person accused (charged) of committing an offence (a crime; an act defined as punishable under criminal law)

• The drinking straw is a very thin pipe which is used to drink Soft drinks.The drinking straw works on the existence of atmospheric pressure.
• A glass tube with a nozzle and Piston for sucking in and ejecting liquid in a thin stream is called syringe. The syringe works on the existence of atmospheric pressure. When the nozzle of a syringe is dipped in a liquid and its piston is withdrawn, the pressure inside the syringe is lower.
• Dropper is a short glass tube with a rubber bulb at one end and a nozzle at the other end.When we press the rubber bulb of the dropper by keeping its nozzle dipped in the liquid , air present in the glass tube and bulb is seen to escape in the form of bubbles. Due to this ,air pressure inside the glass tube and rubber bulb of dropper is very much reduced.

Five rational numbers greater than –2 are :
{tex}\frac{{ - 3}}{2}, - 1,\frac{{ - 1}}{2},0,\frac{1}{2}{/tex}

The smallest cell is Mycoplasma (PPLO-Pleuro pneumonia like organims). It is about 10 micrometer in size. The largest cells is an egg cell of ostrich.

fresh, energetic and active.

Ploughing can promote the growth of earthworm in the field. The loose soil helps in the growth of worms and microbes present in the soil as they help in turning and loosening of soil.

In large fields,wheat and paddy crops are cut by a motorised machine called harvester. Harvesting is either done manually by a sickle or by a machine called harvester.
