  1. Wow, such persons are a blessing to make our earth drearier. #savetheearthfromthem
  2. Thanks swansot.
  3. OK...Upon thinking, I see that v=kx/t is wrong since v gets the unit Hz if the above formula is applied.
  4. Why?[math] x=vt=f\lambda t= \frac{\omega \lambda t}{2 \pi} = \frac{\theta \lambda t}{2 \pi t} = \frac{\theta \lambda}{2 \pi} [/math]
  5. Any physical disturbance distorting the curvature of space-time creates gravitational waves.
  6. So, that is not a separate coordinate.
  7. I'm not sure what you mean by size. An observer at a distance of r from centre of the earth will measure earth's size as r. So, it becomes one of the coordinates required to interpret the observer's position in a spherical coordinate system, the other two being latitude and longitude.
  8. I am really unknown of this term EMR. A more detailed explanation will be helpful.
  9. Yes true, empirical data itself has a logical sequence which makes it valid.
  10. Hello, If there's a wave having velocity v, such that in time t, it has travelled a distance of x, then will the equation relating v and x be v=kx/t, where k is its wavenumber.
  11. Logic is above all. Little children are advised to play with building blocks and abacus because it develops their logical thinking pattern. If you make a scientific theory but it lacks in clear-cut logic, then your theory is invalid. So, logic is required for everything.
  12. Nuclear fusion certainly does this.
  13. Logic is behind numerology and mathematics.
  14. If the current is strong enough and is made to flow through the steel piece for a good deal of time, the magnetic field will increase and it will last permanently.
  15. Can anyone guide me?
  16. Plant the 4 seeds in the form of a square, that is, each seed on each vertex of the square.
  17. It will be great if there is an SFN app for smartphones.
  18. Science is the study of the nature of Nature.
  19. I am surprised and horrified that global warming is good for us. I would rather die in a car accident than die due to suffocation in a CO2-concentrated atmosphere.
  20. A little query- the earth's axis is tilted at 23. 5 degrees, isn't so?
  21. Yes that will be. Sorry if it's off-topic.
  22. The first reaction is indeed possible as it is the combustion of methane. The reverse reaction is doubted, extreme temperature and pressure may facilitate it.
  23. You can calculate the amount paid per day and find the amount paid in a year as- $1000 per week. So, $(1000/7) per day. So, in a year, you get = $(1000/7 *365) = $52142.86
  24. If the particles of wood ash are large enough to settle down in a while, then sedimentation may be useful.
