Two Sources of owner’s fund that can be used for raising finance by business:

a) Equity shares: Equity shares is the most important source of raising long term capital by a company. Equity shares represent the ownership of a company and thus the capital raised by issue of such shares is known as ownership capital or owner’s funds. Equity shareholders do not get a fixed dividend but are paid on the basis of earnings by the company. They are referred to as ‘residual owners’ since they receive what is left after all other claims on the company’s income and assets have been settled. They enjoy the reward as well as bear the risk of ownership. Their liability, however, is limited to the extent of capital contributed by them in the company. Further, through their right to vote, these shareholders have a right to participate in the management of the company. 

b) Retained earnings: A company generally does not distribute all its earnings amongst the shareholders as dividends. A portion of the net earnings may be retained in the business for use in the future. This is known as retained earnings. It is a source of internal financing or self financing or ‘ploughing back of profits’. The profit available for ploughing back in an organisation depends on many factors like net profits, dividend policy and age of the organisation. 

(c) the utensil is made the cathode and pure zinc is made the anode.

Explanation:

The zinc serves as a sacrificial anode, so that it cathodically protects exposed steel.

The Correct option is (B).

Explanation:

Heat has the same units as work. Both heat and work have same

SI unit Joules.

The correct option is (a) 2.2 x 10⁸ Pa

Explanation:

We have change in length due to the change in temperature (considering no obstruction) 

ΔL= αLΔT 

or 

ΔL= 1.1 x 10^-5 x 0.10 x 100 = 1.1 x 10^-4 m 

Now pressure which needs to be applied would be given using

F/A = Pressure = (ΔL x Y)/L = (1.1 x 10^-4 x 2 x 10¹¹)/0.1

(Here ΔL is the expansion prevented) 

= 2.2 x 10⁸ Pa

The correct option is (a) Rs. 1280

Explanation:

Now share of A and B is 2:3

So options B and C are not possible.

Consider

Option (a) i.e.

Share of A = Rs. 1280

Share of A/ Share of B = 2/3

Share of B = 3/2 x A's share = 3/2 x 1280 = Rs. 1920

Similarly B:C = 4:5

Share of C = 5/4 x B's Share = 5/4 x 1920 = Rs. 2400

Similarly C:D = 6:7

Share of D = 7/6 x C's Share = 7/6 x 2400 = Rs. 2800

Total = Rs. 8400

Total is Rs. 8400. So answer is Option (a) i.e. Rs. 1280.

Environment is everything that is around us. It can be living (biotic) or non-living (abiotic) things. It includes physical, chemical and other natural forces.In the environment there are different interactions between animals, plants, soil, water, and other living and non-living things.

Things we Can Do to Save the Environment

• Stop eating meat (or at least reduce it). ...
• Stop eating dairy. ...
• Change your car driving habits. ...
• Notice how you use water. ...
• Reduce the amount of paper in your life. ...
• Use a refillable water bottle and reusable lunch containers. ...
• Be mindful of what you throw in the trash. ...
• Bag it yourself.

The condition of our environment is getting declined day by day because of the pollution and global warming. We should celebrate and promote eco-friendly development in our country in order to save the environment for better future.

The environment in our daily life is very important infact it is vital for human being. If you look around yourself and observe all that is present in your surrounding is environment.

" Environment is a place where different things are such as a swampy or hot enviroment. It can be living (biotic) or non-living (abiotic) things. It includes physical, chemical and other natural forces".

I will give you a few more examples which will explain the importance of environment in our life further. The air is very important for not only human being but other living things also. We can not imagine our life without air because it provides oxygen to us. Even if this air get polluted we face many problem and got ill. So not only environment but a clean environment is very important for human being.

Similarly soil is necessary for crop production, plantation of trees and for making our houses. This soil is a part of environment. again this prove the importance of environment in our daily life.

Hope with these example you have understood the importance of environment in our day life.

The bond that forms a semiconductor is Covalent.

Ancient India’s most famous mathematician and astronomer Aryabhata is widely recognized for contributing the concept of zero to the world. As we know zero has formed the basis for the evolution of modern mathematics.

The correct options is; (b) refraction

The correct option is: (b) (i) & (iii)

The correct option is: (d) Only (3)

Explanation:

Because they have equal momenta, hence equal mv, the heavy body will move very slowly and the light body will move very quickly. As Kinetic energy is 1 / 2 mv² . Thus the speed of the light body will be high giving higher kinetic energy to it in comparison to the kinetic energy of heavy body.

Concepts and reason
The concept used to solve this problem is that a buffer is formed by the combination of a weak acid and its salt of a strong acid or by the combination of a weak base and its salt of strong acid.

Fundamentals
A buffer solution is a solution that resists change in pH on addition of a strong base or a strong acid.

Buffer solutions are of 2 types:

1. Acidic buffer- This is formed by a weak acid and its salt of strong base.
2. Basic buffer- This is formed by a weak base and its salt of strong acid.

Part A
HCN and NaCN form a buffer in aqueous Solution.
Part B
HCl and NaOH don’t form a buffer in aqueous Solution.
Part C
NaOH and NaCN will not form a buffer in aqueous Solution.
Part D
HCl and HCN don’t form a buffer in aqueous Solution.
Part E
HCl and NaCl will not form a buffer in aqueous Solution.
Part F
NaCN and KCN don’t form a buffer in aqueous Solution.

Every integer is a rational number but a rational number need not be an integer. 

We know that 1 = 1/1, 2 = 2/1, 3 = 3/1, 4 = 4/1 and so on ……. . 

also, -1 = -1/1, -2 = -2/1, -3 = -3/1, -4 = -4/1 and so on …….. . 

In other words, any integer a can be written as a = a/1, which is a rational number. 

Thus, every integer is a rational number. 

Clearly, 3/2,-5/3, etc. are rational numbers but they are not integers. 

Hence, every integer is a rational number but a rational number need not be an integer.

Examples : 

(i) 2/5 

2/5 is not an integer. Since we cannot express 2/5 without a fractional or decimal component 

(ii) 8/4 

8/4 is an integer. Since if we simplify 8/4 to its lowest term we get 2/1 = 2, which is an integer.

The correct option is: (c) Both 1 and 2

Explanation:

When a light wave passes from one medium to other, its frequency remains constant but its speed and wavelength change.

The correct option is: (d) 1, 2 and 3

Explanation:

Refractive index of a medium depends on its nature. 

Refractive index (µ) is also given by

μ = sin i / sin r

where i = angle of incidence

r = angle of refraction

Thus, µ depends on the angle of incidence.

Again, 0 = C₀ /  C where C₀ is the velocity of light in

vacuum and c is the velocity in a medium. We know that frequency remains constant when light passes from one medium to others, therefore,

µ = λ0 / λ

The colour of light depends on wavelength. Thus, µ depends on the colour of the incident ray

The correct option is:(c) Both 1 and 2

Explanation:

The ISRO is designing a Geo imaging satellite (Gisat) which is planned to be launched during 2016–17. It will carry a GEO imager with multispectral (Visible, near–infrared and thermal) and multiresolution (50m to 1.5 km) imaging instruments. It will acquire images of a geographical strip and also provide near real-time images of large areas of the country.

(d) all the above

DRAMs are less expensive and slower than SRAMs. DRAM requires to be refreshed periodically as opposed to the SRAM. DRAM has higher bit density and lower power consumption.

The correct option is: (b) 2 and 3 only

Explanation:

The air version of Brahmos has been successfully test-fired recently. Brahmos-II will be hypersonic cruise missile with a range more than 300 km.

The correct option is: (b) (2) only

Explanation:

There is a difference in acceleration due to gravity at equator and poles. The gravity is more on the poles due 2 factors:- 

(1) the effect due to the angular rotation of earth is minimum or zero at poles. 

(2) the earth is flat is towards the poles sog is more at poles.

Diagonal of a square =12√2 cm

If each side of the square be a cm then

a√2 = 12√2 cm

a = 12 cm

Side if square = 12 cm

 Perimeter of square = 4 x side =  4 x 12 cm = 48 ​cm

 Perimeter of equilateral triangle = 3a where a is side of the triangle

48 cm = 3a

a = 48/3 cm = 16 cm

Area of equilateral triangle  = √3/4 a²

= √3/4 x 16 cm x 16 cm

= 64 √3 cm²

deBroglie wavelength is λ = h/(mv)

Kinetic energy is K = ½mv² 

so v = √(2K/m)

λ = h/(m√(2K/m)) 

= h/(√(2Km²/m)) 

= h/(√(2Km) 

= (h/√2)(1/√(Km))

So λ is proportional to 1/√(Km)

For the electron m = 1/2000 amu approx and K =16E. 

1/√(Km) = 1/√(16E x (1/2000)) = 11.2/√E approx

For the proton m = 1 amu approx and K =16E. 

1/√(Km) = 1/√(16E x 1) = 0.25/√E

For the alpha particle m = 4 amu approx and K =4E 

1/√(Km) = 1/√(4E x 4) = 0.25/√E

So the order of their wavelengths (shortest to longest) is: 

proton and alpha particle equal, electron shortest.

If you inspect the expression 

1/√(16E x (1/2000)) 

1/√(16E x 1) 

1/√(4E x 4) y 

The quantitative ratio of their wavelengths is: λp:λα:λe = 0.25:0.25:11.2.
