It is a BASE as it TURNED a red LITMUS paper to BLUE

When we PUT LITMUS paper in acidic medium it turns RED ... while in BASIC turns blue...
hope it helps!! :)

it can be treated either by root canal or doing the USE of HYDROZEN PEROXIDE

Endothermic REACTION is a process by which a substance or object absorbs heat energy.
FOR eg. ammonium NITRATE dissolving in solution is an endothermic reaction, heat energy is ABSORBED from the environment.
Hope it HELPS...

When the amount of work DONE on moving a 1 C of CHARGE from 1 point to the other is 1 Joule , then 1V of potential difference is APPLIED.

Potential difference -- Work done / charge

Lightning is a sudden electrostatic DISCHARGE that OCCURS typically during a thunderstorm. This discharge occurs between electrically charged REGIONS of a cloud (called intra-cloud lightning or IC), between TWO clouds (CC lightning), or between a cloud and the ground (CG lightning).

If you are in class 10th or lower
then, the ANSWER is
There are two ELECTRONS in the outermost orbit of the magnesium atom. HENCE, the VALENCY of magnesium is 2

Malleability of any METAL is the key constituent for Jewellery Making. GOLD is the most suitable among precious Metals., as it is the most maleable metal.

While, for IMITATION and Fashion Jewellery Brass (Brass is a mixture of Zinc and Copper) is best. However, there are different grades of Brass and the ONES with higher content of Copper ( atleast 70% copper) is better for jewellery.

Its only TRANSCRIPTION of DNA

First of all it should be ELECTRONS in PLACE of ELECTIONS and no. of electrons = ATOMIC no. of a neutral atom.therefore the no. of electrons will be 6

It provide stability to the atom and also PREVENT PROTON from REPELLING and other

CROSS-CUTTING DIFFERENCES:

1.If social differences cross-cut one another,it is difficult to pit one group of people against other.

2. It means that a group that share a common interest on one issue are LIKELY to be on different sides on a different issue. In here, it is easy to accommodate and no tensions.

3. Example -NORTHERN IRELAND & Netherlands both are predominantly CHRISTIANS but divided between Catholics & Protestants. In Northern Ireland the Protestants have stayed richer than the Catholics here class & religion overlap each other, Catholics have been poor & have suffered discrimination where as in Netherlands , class & religion tend to cross-cut each other and both are equally likely to be rich or poor.Social discrimination in Netherlands is not overlapped by economic issues both the christian communities have equal NUMBER of rich and poor. It means they have conflict in Northern Ireland and it is not so in Netherlands.

4. Cross-cut social differences are easier to accommodate.

Tsunami are actually waves CAUSED by sudden movement of the ocean due to earthquakes, LANDSLIDES on the sea floor, land SLUMPING into the ocean, major VOLCANIC eruptions or large meteorite impacts. ... the top of an underwater VOLCANO may collapse downwards, so that the overlying water also drops.

m = 1 kg

f = 6 N

S = 12 m

u = 0 m/s ( the OBJECT is at rest )

f = m * g

6 = 1 * g

g = 6 m/s^2

by Newton's SECOND law ------->

S = ut + 1/2 * GT^2

12 = 0 * t + 1/2 * 6 * t^2

12 = 3 * t^2

12/3 = t^2

4 = t^2

t = 2 second

Therefore the time taken is t = 2s.

Hope it helps you :)

⭐HELLO BRAINLY USER⭐

The U shape MAKES the magnetstronger by pointing the POLES in the same direction. Originally created as a REPLACEMENT for the bar magnet, this shape has become the universal symbol for magnets. It can be used to pick up METAL objects of any size depending on the strength of the horseshoe magnet.

Fuel is any substance used to produce heat and energy through a chemical or nuclear reaction. The energy is used by the conversion of a portion of the fuels mass. In India, we are suffering a severe fuel crises. In view of this, the Petroleum Conservation Research Association is encouraging fuel conservation. Our goal should be to reduce gasoline consumption progressively each year.

Fuel serves as a major part of our energy requirement. Petroleum, a major fuel is WIDELY used in our everyday lives and also used to power AUTOMOBILES, produce containers and to keep us warm. All plastic is made from it and used in cars, houses, computers, paraffin wax, paints and pharmaceuticals, at times it is also used as a solvent found in large quantities below the surface of the Earth and is used as fuel and raw material in the chemical industry.

Conserving energy and fuel makes sense on different levels. It is WISE to turn off your car at traffic signals, minimize the use of brakes and encourage car pooling. Spread awareness for fuel conservation amongst your friends
relatives. There are three areas where the motorist can save fuel- proper maintenance, efficient driving habits and intelligent purchase of a vehicle. One of the best ways to save fuel is to reduce speed, as speed increases, fuel ECONOMY decreases exponentially. Tyre pressure and car's dirty air filter should be checked, if not, it could harm its performance and economy. Petrol is also called black gold. 
Hope It is use full.✌

A VECTOR REFERS to any quantity that NEEDS a magnitude and a direction in ORDER to FULLY describe the quantity.

Answer:

• Life in the Sahara desert Living things struggle to survive in the Sahara. It is one of the driest places on Earth - hot during the day but cold at night. To survive there, plants and animals need to FIND water and hold onto it Some desert SPECIES have very short LIVES. They grow and reproduce quickly when it rains. It is easier for seeds or eggs to survive for long PERIODS without water. Some lie dormant for many years before it rains again Saving water. Most desert plants have long roots near the surface. They absorb rainwater quickly before it soaks into the sand. They also have tiny leaves. spines or a waxy coat to stop water evaporating from their leaves. Some desert plants use swollen stems or fleshy leaves to store water. Others dry out but can recover when it rains. Most desert animals don't drink. They get water from their food or stores of fat. They stay UNDERGROUND during the day to keep cool. They don't sweat and their urine is very concentrated. Desert animals like this lizard extract water they need from their food.

The process by which LIQUID CHANGES into gaseous or VAPOUR state is CALLED evaporation..

Sandalwood is a class of woods from trees in the GENUS Santalum. The woods are heavy, YELLOW, and fine-grained, and unlike many other aromatic woods, they retain their fragrance for decades. Sandalwood oil is EXTRACTED from the woods for USE.

The mixture which has equal composition of all the COMPONENTS is known as homogeneous mixture. in this mixture the composition is IDENTICAL everywhere.
E. G:-
* water in a BOTTLE
* composition of chemical ELEMENTS

It was a project introduced in the year 1986 to reduce the increasing pollution levels in the RIVER Ganga.The former prime minister of India,Rajeev Gandhi launched a programme named Ganga ACTION plan in order to reduce the pollution of River Ganga.

Objectives for the plan;

1)Rehabilitation of soft shelled turtles which may be used for the purpose of pollution abatement of the river.

2)Control of pollution such as waste from agricultural,human defecation,THROWING of unburnt & half BURNT bodies into the river.

3)Treatment of the domestic sewage,industrial sewage,industrial waste,toxic chemicals,& pollutants discharge into the river.

4)To improve the water quality of river Ganga.

Millions of people bathe in river Ganga because of its HOLY aspect which may leads to its pollution. 

Characteristics of Viruses

1-They are enclosed in a PROTECTIVE envelope.

2-They have spikes, which helps them to ATTACH to the HOST cell.

3-They are non cellular.

4-They do not respire, do not metabolize and do not grow but they do reproduce.

5-They contain a protein coat called the capsid.

6-They have a nucleic acid core CONTAINING DNA or RNA.

The speed of an OBJECT is defined as the distance it has traveled DIVIDED by the amount of TIME elapsed. The velocity OFTHE object is similar to speed but has one MAIN difference: velocity takes into account the direction of an object

2FeSO4 -----> FE2O3 +SO2+SO3

IT IS FOR HEAT

2H2O -----> 2H2 + O2

IT IS FOR ELECTRICITY

Newton's SECOND Law of motion states that the rate of change of momentum of an OBJECT is proportional to the applied UNBALANCED force in the direction of the force. 

F = mv - MU / t

= m ( V - u ) / t

F = m a
Proved

When a MASS of 1 kg produces an acceleration of 1m/s^2 then 1N of force is applied..
