  1. To harness solar energy, we have to be technically very advanced. During the Industrial Revolution of 18th century our community was not so advanced.
  2. Inertia of motion according to Newton's First Law of Motion.
  3. Wait a minute, I am talking about shells in Bohr's model of the atom, not orbitals in the modern atomic model.
  4. Doppler's effect is related to frequency of light. Even if light consists of photon, there is no difference to the frequency of the photons and they can be treated alike.
  5. To convert a magnetic ferromagnetic substance into non-magnetic, we have to apply AC at its ends (that will disorganise the molecular magnets.)
  6. As the wheel rotates, it has centrifugal force which the throws away the material.
  7. Mathematically, we have- Perimeter of a circle = Circumference© [math]C=2\pi r[/math] Area of a circle(A)[math]=\pi r^2[/math] So, [math] A=\frac{Cr}{2} [/math] But with same perimeter C, we can get an area of a square as- side of square(s)=[math]C/4[/math] Area[math]=\frac{C^2}{16}[/math] So same perimeter C, but different areas. A logical way to understand this fact is to think that area is the integration of a function under definite points. Perimeter is the functions length upto a point.
  8. Forget balancing, is the equation possible???
  9. For the Independence of India, I suggest look the following points. 1. The establishment of the British East India Company and the seize of the kingdoms under Robert Clive ( emphasis on the Battle of Plassey in 1757) 2. The First War of Independence (1857) 3. Rise of Nationalism in India (emphasis on Raja Rammohan Ray, Syed Ahmed Khan, etc) 4. Formation of Congress, its subsequent struggles 5. Assertive Nationalism (emphasis on efforts of Tilak, Bipin Chandra and Lajput Ray), Partition of Bengal (1905) 6. Lucknow Pact, Home Rule Movement 7. Gandhiji's struggle (Non-Cooperation Movement, Civil Disobedience, Quit India ) 8. Leadership of Subhash Chandra Bose 9. Partition and Independence of India.
  10. Perimeter is the sum total of the lengths of the sides of a geometrical shape. Area is the amount of plane occupied by the boundary of a geometrical shape. So, it gets clear that area has no relations with perimeter. It also becomes clear from your situation.
  11. As far as I have learnt, I know that the Higgs boson is responsible for the mass of all other non-bosons.
  12. Dark matter and dark energy are two such things, although they are matter and energy in name. They are really some confusing stuffs.
  13. It's a great experience to participate in an inter-school debate competition. It gives you an opportunity not only to discover yourself but also to boost your confidence and learn many things. :)

  14. There can be many different possible hypothetical reactions, but only one is correct at a given temperature and pressure and other conditions present.
  15. Cardiac muscles is one.
  16. Hey Itoero, the diagram you posted shows the blind spot of the eye, isn't it?
  17. When the OP told about disappearance of a body, it struck to my mind about the annihilation of particles.
  18. The origin of God dates back from the Stone Age of early humans. It began because early men feared the forces of nature and started to worship them in order to appease them. And he then personified the forces of nature.
  19. That will be good. But before making models of complex organic molecules one must learn the basics.
  20. Excellent. Was the problem tough??
  21. Well, I have no idea whether two simultaneous reactions involving same reactants in the same concentration to yield different products is possible or not. I think it's impossible.
