linkmay/june 12 qp 21 question 3 (b).can some1 explain
I1/I2= A1^2/A2^2
I1= Initial intensity
I2= New intensity
A1= Initial amplitude
A2 = New amplitude
I1/ 2I1 = (2.8)^2 / A2^2.. We have to find A2.. So solve this you'd get the answer.. I think its 3.959 ..
3bi) speed max at mean position which means any time when disp 0 hence 0.2may/june 12 qp 21 question 3 (b).can some1 explain
obviouslyThank you very much ! this was very helpful
I wanted to know whether this formula can be applied to ALL the intensity questions Thank you again!
Could anyone please explain how the relationship between Intensity and amplitude of a wave? I know that intensity = amplitude^2 but I always get confused when we are asked questions like.. twice the intensity, half the intensity, twice the amplitude etc. Please help me understand that.
Thanks
ummm probably because they have asked for the weight down the slopehttp://papers.xtremepapers.com/CIE/Cambridge International A and AS Level/Physics (9702)/9702_s11_qp_21.pdf Q2b daredevil syed1995 why isnt the weight component shown verticle ?
no the weight is taken perp to the ground so y we taking paralell to slope this concept bugged me throughout the yearummm probably because they have asked for the weight down the slope
would you please explainobviously
Np
You do realize if you release a ball from rest on a slope it starts to move down the slope. Clearly, its the weight component "DOWN THE SLOPE" (along the slope) which makes it move down. You have to find that component which does this.no the weight is taken perp to the ground so y we taking paralell to slope this concept bugged me throughout the year
