Weight will be less at equater as centrigugal force is exerted due to rotation of earth

Lekha Raj 7 years, 10 months ago

I think an object would weigh 0.5% more at poles than at equator.

Lekha Raj 7 years, 10 months ago

I think ans should be that the acceleration due to gravity changes according to location.It has higher value at poles than at equator.This simply implies that man would weigh more at pole than equator. W= mg...................From this formula when 'g' inc , the weight of any object automatically inc.

Key Differences Between Diffraction and Interference

  1. Diffraction is the result of light propagation from distinct part of the same wavefront. While interference is the result of the interaction of light coming from two separate wavefronts.
  2. The width of the fringes in case of diffraction is not equal while the fringe width in case of interference is equal.
  3. Diffraction possesses poor contrast between maxima and minima while interference exhibits good contrast between maxima and minima.
  4. For diffraction to take place slit or obstacle is necessarily required but for wave interference there exists no such requirement.
  5. Due to diffraction, the direction of propagation of wave gets changed. Whereas in case of interference the superposed wave travels in the same direction.
  6. In diffraction the spacing between different fringes is non-uniform. However, in the case of interference, the spacing between the fringes exhibits uniform nature.
  7. The minimum intensity points in the case of diffraction are not completely dark. As against in case of interference, the points of minimum intensity shows complete darkness.

Its very helpful asim khan ...my teacher teach the same method

Asim Khan 7 years, 10 months ago

Hey! Before giving the answer to your asked question I want to appreciate your question bcz it was the same problem with me also when I just came in class 11 and I think that many others may have the same. But now I don't find any problem regarding this. You might be thinking...How??? It's very easy. First of all be relax minded while attempting the questions. Read the given question atleast two times along with underlining the main data/information given into the question. Then create the picture of the asked query in your mind.Now how fast you are able to mug up or create the picture depends on the level of your preparation.The next step is to start doing the solution in the answer sheet. Now don't just start solving the question directly, I would advise you to write the given data into the question again in your answer sheet so that you could get the exact idea about the asked question. So in this way you may improve your weakness towards getting the question quickly. Actually I followed the same and now I don't have such problems. Hope it helps!!! Best wishes...
