2.

Some farmers in the UK use a technique called precision farming. This involves using global positioning systems (GPS) and soil analysis to map out which parts of their fields need the most fertilizer. Find out how it works.

Answer»

Precision farming involves collecting timely Geospatial information on soil - plant - animal requirements and prescribing and Applying site specific treatments to increase agricultural production and protect the environment.

How it works :

1.) The information collection is done using GPS.

2.) The GPS provides information on mapping field boundaries, ROADS, irrigation systems and problem areas in crops such as weeds or disease.

3.) The accuracy given by the GPS allows farmers to CREATE farm maps with PRECISE acreage for field areas, road location and distance between point of interest.

4.) This information obtained allows farmers to accurately navigate to specific locations in the field year after year to collect soil samples or monitor crop conditions.

With this it ensures specific areas are ADDRESSED adequately.

Answer»

Hey dear !!!!!
Here is your answer :-

As we know that :-
1KWH = 1KW * H = 1000 W * 3600s

= 1000j/s * 3600 = 3600,000 J

therefore :-
1kwh = 3.6 * 10^6.

What is difference between a complete parasite and a partial parasite. Give examples of each.

Answer»

Total parasitic plants are those which are fully DEPENDENT on their hosts for GROWTH and survival. Total parasitic plants are usually achlorophyllous. Cuscuta reflexa, Orobanche aegyptiaca, Striga asiatica etc. are the examples of total parasitic plants.

Partial parasites are those which are partially dependent on their hosts. Partial parasitic plants are usually chlorophyllous therefore they are dependent on their hosts for water and NUTRIENTS only. Rest of the job is being DONE by their green leaves. Dendropthoe falcata, Viscum album, SANTALUM album etc. are the examples of partial parasites.

Human evolution began approximately 7 crore year ago

Answer»

Hiii....
hope it WOULD help
it's in encyclopaedia....

Human evolution is the lengthy process of change by which people originated from apelike ancestors. Scientific evidence shows that the physical and behavioral traits shared by all people originated from apelike ancestors and evolved over a period of approximately six million years.

One of the earliest defining human traits, bipedalism -- the ability to walk on two legs -- evolved over 4 million years ago. Other important human characteristics -- such as a LARGE and complex brain, the ability to make and use tools, and the capacity for language -- developed more recently. Many advanced traits -- including complex symbolic expression, art, and elaborate cultural diversity -- emerged mainly during the past 100,000 years.

Early humans first migrated out of Africa into Asia probably between 2 million and 1.8 million years ago. They entered Europe somewhat later, between 1.5 million and 1 million years. Species of modern humans populated many parts of the world much later. For instance, people first came to Australia probably within the past 60,000 years and to the Americas within the past 30,000 years or so. The beginnings of agriculture and the rise of the first civilizations occurred within the past 12,000 years.

 Paleoanthropology is the scientific study of human evolution. Paleoanthropology is a subfield of anthropology, the study of human culture, society, and biology. The field involves an understanding of the similarities and differences between humans and other species in their genes, body form, physiology, and behavior.

Early human fossils and archeological remains offer the most important clues about this ancient past. These remains include bones, tools and any other evidence (such as footprints, evidence of hearths, or butchery marks on animal bones) left by earlier people. Usually, the remains were buried and preserved naturally. They are then found either on the surface (exposed by rain, rivers, and wind erosion) or by digging in the ground. By studying fossilized bones, scientists learn about the physical appearance of earlier humans and how it changed. Bone size, shape, and markings left by muscles tell us how those predecessors moved around, held tools, and how the size of their brains changed over a long time. Archeological evidence refers to the things earlier people made and the places where scientists find them. By studying this type of evidence, archeologists can understand how early humans made and used tools and lived in their environments.

The process of evolution involves a series of natural changes that cause species (populations of different organisms) to arise, adapt to the environment, and become extinct. All species or organisms have originated through the process of biological evolution. In animals that reproduce sexually, including humans, the term species refers to a group whose adult members regularly interbreed, resulting in fertile offspring -- that is, offspring themselves capable of reproducing. Scientists classify each species with a unique, two-part scientific name. In this system, modern humans are classified as Homo sapiens.

Evolution occurs when there is change in the genetic material -- the chemical molecule, DNA -- which is inherited from the parents, and especially in the proportions of different genes in a population. Genes represent the segments of DNA that provide the chemical code for producing proteins. Information contained in the DNA can change by a process known as mutation. The way PARTICULAR genes are expressed – that is, how they influence the body or behavior of an organism -- can also change. Genes affect how the body and behavior of an organism develop during its life, and this is why genetically inherited characteristics can influence the likelihood of an organism’s survival and reproduction.

Evolution does not change any single individual. Instead, it changes the inherited means of growth and development that typify a population (a group of individuals of the same species living in a particular habitat). Parents pass adaptive genetic changes to their offspring, and ultimately these changes become common THROUGHOUT a population. As a result, the offspring inherit those genetic characteristics that enhance their chances of survival and ability to give birth, which may WORK well until the environment changes. Over time, genetic change can alter a species' overall way of life, such as what it eats, how it grows, and where it can live. Human evolution took place as new genetic variations in early ancestor populations favored new abilities to adapt to environmental change and so altered the human way of life.

a particle moving with acceleration and then retardation covers a distance of 4 km prove that 1/a1+1/a2=4min^2/km

Answer» 1) Direct Proportionality between Time and Distance (When Speed is CONSTANT)

When speed is constant distance will vary as time

Car A moves for 2 hours @ 25kmph ---------> d = s X t -------> 50 = 25 X 2
Car B moves for 3 hours @ 25kmph ---------> d = s X t --------> 75 = 25 X 3
Here (tA / tB) = (dA / dB) -----> time ratio = distance ratio = 2 : 3


2) Direct Proportionality between Speed and Distance (When Time is constant)

If time of two bodies or motion is constant, then distance will vary as speed
Here (S1 / S2) = (d1 / d2)

If two cars start simultaneously from opposite ends towards each other. They meet at point ‘C’
In this case distance covered by each car will vary as their speeds since they travelled for equal period.

Suppose the distance AB = 900 km Speed A = 25kmph Speed B = 20kmph
In this case their meeting point (C) will be (S1 / S2) = (d1 / d2) ------> 25/20 ----> 5/4 = 500 / 400 i.e. 500 kms from A


3) Inverse Proportionality between Speed and Time (when Distance is constant)

If the distance to be covered is constant, then time will vary inversely as speed i.e. as speed increases, time decreases and vice versa.
(S1 / S2) = (t2 / t1)

Example 1 :- A Train meets with an ACCIDENT and moves at ¾ of its original speed. Because of this it delayed by 20 minutes. What is the original time for the journey beyond the point of accident.
-----> Speed becomes ¾ hence time becomes 4/3 -------------------- remember (S1 / S2) = (t2 / t1)) 
-----> increased time is 1/3 = 20 minutes. So original time = 60 minutes. (1 belongs to 20mins, then 3 belongs to 60mins)

In other WORDS

------> speed dropped to 75% and time increased to 133.33% ----> increased time = 33.33% = 20 minutes
Now 33.33 % belongs to 20 minutes, So 100% belongs to 60 minutes.

Example 2 :- A Man walked from his HOUSE to office at 5kmph and got 20 minutes late. if he had travelled at 7.5kmph, he would have reached 12 minutes early. The distance from his house to office is?

Here s1 = 5kmph t1 = t2 + 20 + 12 s2 = 7.5kmph t2 = t2
(S1 / S2) = (t2 / t1) ------> (5/7.5) = (t2 / t2 + 32) ---------> 5t2 + 160 = 7.5t2 -------> t2 = 64 minutes 
So distance = 7.5 X 1.7 (64 mins) = 8km


Relative Speed


Relative Speed can be viewed as a movement of one body relative to another moving body.


1. Relative Speed of bodies moving in same direction.

In the case of the bodies moving to and fro between two points A and B, The faster body will reach the end first and will meet the second body on its way back. The relative speed S1 – S2 will apply till the point of reversal of the faster body and after that the two bodies will start to move in the opposite directions at a relative speed of S1 + S2. The relative speed governing the movement of the two bodies will alternate between S1 – S2 and S1 + S2 everytime anyone of the bodies reverses the direction. However, if both the bodies reverse their direction at the same instant, there will be no change in the relative speed equation.
In this case, the description of the motion of the two bodies between two consecutive meetings will also be governed by the proportionality between speed and distance – since the time of movement between any two meetings will be constant.

In this case, for every meeting, the total distance covered by the two bodies will be 2d (d = distance between the extreme points). The respective coverage of the distance will in the ratio of the individual speeds. THUS for the 9th meeting the total distance covered will be 9 X 2d = 18d


2. Relative Speed of bodies moving in opposite direction.

In the case of the bodies moving to and fro between two points A and B starting from opposite ends of the path, The two bodies will meet at a point in between A and B, then move apart away from each other. The faster body will reach its extreme point first followed by the slower body reaching its extreme point next. Relative speed will change every time ; one of the bodies reverses direction.
In this case, the position of the meeting point will be determined by the ratio of speeds of the bodies – since the time travelled of both the bodies is same. (Remember (S1 / S2) = (d1 / d2))

Give example how combustion is possible without flame

Answer»

(A-t-A).

The question is about possibility of combustion reaction without producing FLAME.

Yes, it is possible. In some conditions, combustion reaction TAKES place with no flame. We define combustion as a chemical reaction of a material (fuel) with oxygen or an oxidant substance. Appearance of flame in the combustion depends on some factors, such as temperature. For instance, when combustion of a fuel happens at lower temperatures (for instance, below 800–900 deg C, depending on the fuel), the reaction produce flame, but above this range of temperature, the flame is quenched and disappears, but combustion reaction continues.

Production of flame in combustion also depends on how fast the fuel (LIKE a gas) is injected into the burner chamber. The flame can be quenched at high-speed injection conditions of the fuel gas.

A combination of controlling temperature and speed of fuel injection ( as well as using a blend of various substances as fuel) can be applied to find out the optimum and practically feasible conditions for designing a combustion reaction without flame.

In CONCLUSION, combustion does not always produce a flame.
