U did get a head start though.

cud sum1 xplain Q5 of may03??????????

--- Quote from: nid404 on April 29, 2010, 06:15:17 pm ---Q15) A obv  resultant vector x and y components
Q17) D  no change in velocity, therefore no change in k.e
Q22) Density and molecular spacing in solids and liquids is approx the same...hence A
Q28) lambda= ax/ D where a is the distance between the slits, x the distance between the fringes and D is the distance between the slit and screen. to increase separation that is x..
A-> if f is increased means lambda is decreased as v=flambda.....so this is out(cuz lamda and x are directly proportional)
B->lamda increased ...then x will increase...so B
C->decreasing D will reduce x (directly proportional)
D-> increasing a will reduce x (inversely proportional

Q35) R increases with length... so pointer will be moved to Y. But this will cause I=0...V=IR  so V=0
Q36) in the  parallel wire with the 5ohm resistors, 2V is split equally, so potential between source and X= 2/3 source and Y= 2X2/3=4/3
difference is 2/3  which is A

for Q36> why do u consider the resistance of X and Y from the source, why not the 3 resistors directly between X and Y ( 2 from the first path and 1 from the second)??????

nid404:
huh...how 2 and 1.??
please explain what you are trying to say

halosh92:
thankyou so muchhhhhhhhhhhhhhh nid and dude 321
