1. Character -- A figure in a literary work (personality, gender, age, etc). E. M. Forester makes a distinction between flat and round characters. Flat characters are types or caricatures defined by a single idea of quality, whereas round characters have the three-dimensional complexity of real people. 2. Plot –- the major events that move the action in a narrative. It is the sequence of major events in a story, usually in a cause-effect relation. 3. Point of View -- the vantage point from which a narrative is told. A narrative is typically told from a first-person or third-person point of view. In a narrative told from a first-person perspective, the author tells the story through a character who refers to himself or herself as "I." Third –person narratives come in two types: omniscient and limited. An author taking an omniscient point of view assumes the vantage point of an all-knowing narrator able not only to recount the action thoroughly and reliably but also to enter the mind of any character in the work or any time in order to reveal his or her thoughts, feelings, and beliefs directly to the reader. An author using the limited point of view recounts the story through the eyes of a single character (or occasionally more than one, but not all or the narrator would be an omniscient narrator). 4. Setting –- That combination of place, historical time, and social milieu that provides the general background for the characters and plot of a literary work. The general setting of a work may differ from the specific setting of an individual scene or event. 5.Style -- The author’s type of diction (choice of words), syntax (arrangement of words), and other linguistic features of a work 6. Theme(s) -- The central and dominating idea (or ideas) in a literary work. The term also indicates a message or moral implicit in any work of art. {Bohot time lag gya yar}??

What is full form of DNA

Meghna Thapar 4 years, 7 months ago

To Calculate the Value of g:

To calculate the value of g, we should put the value of universal gravitational constant, G = 6.673 × 10^–11 N m² kg^–2; mass of the earth, M = 6 x 10²⁴ kg; and radius of earth R = 6.4 x 10⁶ m in the given equation:

g = GM /r²

g = 6.673 × 10^–11 N m² kg^–2 x 6 x 10²⁴ kg/(6.4 x 10⁶ m)² = 9.8 m/s²

Thus, the value of acceleration due to gravity of the earth, g = 9.8 m s^–2.

ANSWER

A solid weughs 80 gm. in air and 64 gm. in water . Calculate its relative density

Posted by Myself Viv 4 years, 7 months ago

CBSE > Class 09 > Science

1 answers

Yogita Ingle 4 years, 7 months ago

relative density = weight in air / weight in air -weight in water

R.D = 80/80-64
R.D = 80/16
R.D = 5
now,
density of water = 1 g/cm³
so the object would sink .

why do noble gases have valancy zero? state reason

Posted by Jo Tesh 4 years, 7 months ago

CBSE > Class 09 > Science

3 answers

Navjot Kaur 4 years, 7 months ago

The valency of noble gases is zero because their octet is complete. Octet means that outer most orbothas complete eight electrons to stay stable.Hence their valency is also zero

Om Bhimani 4 years, 7 months ago

Because their each shells are complete. Therefore, they form an octet. Or simply they do not have any valence electrons.

ANSWER

in gold foil expriment,99% of alfa particles pass undeviated.if one mole of alfa particles are bombarded on the gold foil, compute the number of alfa particles that would pass undeviated through the gold foil

Posted by Jo Tesh 4 years, 7 months ago

CBSE > Class 09 > Science

1 answers

Meghna Thapar 4 years, 3 months ago

Rutherford postulated that the atom must contain large empty spaces as most of the α-particles passed through it without getting deflected. Some α-particles were deflected by the foil through small angles, while some were deflected through very large angles. Thus, Rutherford concluded that the positively charged particles in an atom must be concentrated in a very small space.

One out of every 12,000 particles were deflected through 180o showing a full rebound. Thus, Rutherford came to the conclusion that all the positive charges of the atom and most of the mass of the atom is concentrated in a very small volume within the atom.

Rutherford named this small space inside the atom as the nucleus of the atom or the atomic nucleus. On the basis of these observations, Rutherford calculated that the atomic nucleus is 10⁵ times smaller than the total area of the atom. The radius of the atom is 10^-8 centimetres while the radius of the nucleus is 10^-13 centimetres.

Thus, we can say that the atom is relatively hollow with a heavy nucleus at its centre. The electrons arranged around the nucleus possess negligible mass.

Mb Vadhel 4 years, 7 months ago

The combining capacity of an atom or element is known as element.

Yogita Ingle 4 years, 7 months ago

It is the ability of an atom to gain or lose electron in order to achieve the noble gas configuration. It refers to the ability of an element to combine with other element. It is obtained by determining the number of electrons in the outermost shell (also called valence shell) of each atom of an element. For instance, sodium has 1 electron in its outermost shell and hence valency of sodium is 1.

The cycling of chemicals between the biological and the geological world is called biogeochemical cycle.
The biotic and abiotic components of the biosphere constantly interact through biogeochemical cycles. During these interactions, there is a transfer of nutrients between living organisms and the non-living environment.
The four important biogeochemical cycles are water cycle, nitrogen cycle, carbon cycle and oxygen cycle.

Yogita Ingle 4 years, 7 months ago

A sound of single frequency is called a tone. A sound that is produced when several frequencies are mixed is called a note. For example a musical note has tones of various frequencies (sounds of different pitch) and amplitudes (loudness). A note has many component waves in it whereas a tone is represented by a single wave form.

A sound of single frequency is called tone. A note has many component wave.

A sponge can be compressed easily still we take it as a solid because they have small minute pores present in them in which air is filled and hence it can be compressed easily when we press it.

A sponge can be compressed easily but still we count them in solids because they have minute pores in it which are filled with air. When we press the sponge air is expelled from its holes making it highly compressible.

ANSWER

The frequency of sound is 100 hertz how many time does it vibrate in a minute

Posted by Intekhab Ahmad 4 years, 7 months ago

CBSE > Class 09 > Science

1 answers

Yogita Ingle 4 years, 7 months ago

The frequency of 100 hertz means that the source of sound vibrates 100 times in 1 second.
[1min = 60 sec]

Number of vibrations in 1 second= 100

Number of Vibrations in 60 Second( 1min)=100× 60 = 6000

Hence, the source of sound vibrates 6000 times in a minute.
