    Graduate How can we say there is Zero G force in space what about SUN's G ?

    ok... planets revolve around sun (Why planets Revolve around sun why not fall towards sun?)... But the rock doesn't revolve and it should fall towards the sun ... ? ------------->it (earth) will fall toward the sun but that's a long time from now :wink:

    Undergrad Solving 4th Degree Equation: √x+y=7, √y+x=11

    thanks guys :) ive found a way out if we take x= l2 and y=n2 then √l2 +y= 7 (√x+y=7) √n2+x =11 (√y+x=11) which becomes l2+y-7=0 (getting rid of root) n2+x-11=0 2 quadratic equn. :) ans sloving it gives...

    Undergrad Solving 4th Degree Equation: √x+y=7, √y+x=11

    √x+y=7 √y+x=11 solving this equation using x=-b√b2-4ac/2a for finding the root is impossible the equation turns out to be of 4th degree or two quadratic eq. can anybody help this isn't a homework , just wanted to know ...;)

    Graduate Light some interesting questions and an observation

    Why does it travel in a particular direction and what determines this ? consider a light source in a universe and a planet 1/2 ly behind it then the direction of light wrt planet can be determined by cartesian 2d graph (basic) relative to any object other objects direction.speed can...

    Graduate Light some interesting questions and an observation

    for you first question :- speed is a scalar quantities so direction of light at a small displacement~~ acceleration can be ignored (pointless) this should be valid for stationary and for body absorbing light " read black body radiation" (for extra coverage) as per Albert. e...
