    Let 1/2-√5 is a rational number. A rational number can be written in the form of p/q where p,q are integers. 1/2-√5=p/q 1/2-p/q=√5 √5=(q-2p)/2q If p,q are integers then (q-2p)/2q is a rational number. Then,√5 is also a rational number. But this contradicts the fact that √5 is an irrational number. So,our supposition is false. Therefore,1/2-√5 is an irrational number Hence proved.

    Archimedes principle state that the substance which is immersed partially or fully in water experienced a force i.e.. BOUYONT FORCE which is equal to the amount of water displaced by the substance. In short , Archimedes Principle = Bouyont force acted on substance = amount of water displaced by substance

    • Development promises a real growth by enhancing total income and standard of living of a person.
    •  Different people have different developmental goals.
    •   What may be development for one mat may not be development for another it may be destructive for another.
    •   Income is the most important component of development, besides seeking more income, one way or other, people also seek things like equal treatment, freedom, security and respect of others.
    •  Similarly, for development, people look at mix of goals.

    Drawback of Dobereiner's triads:

    1. Dobereiner could identify only three triads. He was not able to prepare triads of all the known elements
    2. All the known elements could not be arranged in the form of triads.
    3. For very low mass or for very high mass elements, the law was not holding good. Take the example of F, Cl, Br. Atomic mass of Cl is not an arithmetic mean of atomic masses of F and Br.

    0Thank You

    Meghna Thapar 5 years, 8 months ago

    Law of Triads: 

    When elements are arranged in the order of their increasing atomic masses, the atomic mass of the middle element was approximately the mean of the atomic masses of the other two elements.

    For example: Consider the triad of lithium, sodium and potassium.  The atomic mass of sodium is the mean of the atomic masses of lithium and potassium.

    •The number of elements discovered has increased, making it difficult to remember the behavior and properties of these elements. •Hence it is important to classify elements according to their properties. It is also necessary to understand how they form the compounds. •Grouping of elements into different classes is called periodic classification of elements. •This method is requires arranging the elements that are alike and separating the elements that are unlike. •To compare the properties of elements. It helps us understand how different elements form different compounds.

    Frederic Sorrieu was a French artist who in 1848 prepared a series of four prints visualizing his dream of a world made up of ‘Democratic and Social Republics’. The distinct feature of these prints were the representations of men, nations and allegories. In the first of his print, we can see men and women marching across the statue of Liberty to offer homage. The statue holds a torch of enlightenment and the Charter of the Rights of Man. And finally, the remains of the absolutist institutions can be seen broken and shattered on the Earth indicating the end of conservatism and absolutism.

    The molecules of air and other fine particles in the atmosphere have a size smaller than the wavelength of visible light. Thus, they are more effective in scattering light of shorter wavelengths at the blue end than light of longer wavelengths at the red end.
    Red light has a wavelength greater than blue light. Thus, when sunlight passes through the atmosphere, the fine particles in air scatter blue colour (shorter wavelengths) more strongly than red. The scattered blue light enters our eyes.
    If the Earth had no atmosphere, then there would not have been any scattering. The sky would have looked dark. Similarly, the sky appears dark to aeroplane passengers flying at very high altitudes, as scattering is not prominent at such heights.
