any1????q.26 plssssssssssss
initial momentum of the ball is 2mv before collision... if collision was perfectly elastic one, all the momentum would have been gained by the ball... and this would have made the change in the momentum equal to 4mv.. 2mv-(-2mv)... now it is given that collision is inelastic, it wil losse some of its momentum to the wall.. so now change in momentum will be less than 4mv but cant be less than the initial momentum... so the answer is C.. i think you cannot verify the answer by the calculations...

the new pattern is produced by increasing the distance between the plates... this distance is given by the formula (call this distance be a a=xD/lemda*d... hope you remember this... increasing frequency will dec wavelength... dec in wavelength will increase a:....
I'm sorry but could you explain this formula? Like what the letters represent and stuff, because it seems unfamiliar. What are the a, x , D and d in this situation? Thanks.
October 2011, varient 12, question 39, the Option B is also correct, y the answer is set to option C??
