ReplyDeleteraghvendra pandey sir......
ReplyDeleteare the above answers are correct?
cp verma .
ReplyDeletesorry MR.Anonymous i accept some ans's i posted is wrong. and how can u say everything is wrong.and i am misleading u???
i am really very to post on your site.
sodiun D2/D1 ratio lies between 1.2 and 1.8. so i think ratio of inensities are 2/3.
ReplyDeleteM@H@BOOB.KP
ReplyDeleteBOOLET CODE B
PART A
1.most abundant elemt=oxygn
2.numbr systm, decimal equivalent =11
3.segment of circle,angle are equal=85
11.animal without modified leg=butterfly
14.jar containing an iron block put into water=level fall
15.sun becomes black hole =none of planets
18.droplets of herbicide solution on leaf=B>C>A
20.cylinder with 4 blades and bullet=missing blade reduced by 1/4
Pandey G ye aap ka answer hai ya you have try to solve this.
ReplyDeletePlease suggest the answer of g.s. for water level to be remains same.Please suggest
Please any one tell me what is the cut off for physical science??
ReplyDeleteanswer for spin question is 7/2+ and 7/2+
ReplyDeleteRaghavendra sir, please explain your answer for Qno. 13
ReplyDeleteQno.2 in set-A or Qno.6 in set-B may have the ans.1
ReplyDeletebecoz this is the horizontal case and will follow the relation time=distance/velocity.
if it is in the case of vertical case, option 4 will be the correct answer.
for set-B,
ReplyDelete2---ans.3
8----ans.1
9----ans.3
10---ans.1(narrow size distribution as seen from the given fig)
12---ans.2(157th position mutated to the end codon. so polypeptide chain will contain 156 AA)

Hi, every one the comments will be useful to all if post explanations also.
ReplyDeleteby checking the answers from up to down in this page i am getting confused.whose answers are correct in these?
ReplyDeletewill anyone tell me?
wat about the cut off marks in each section?
animal without modified leg-answer is butterfly
ReplyDelete@Anonymous
ReplyDeletewhat about sparrow?
criteria of passing in this examination is it necessary to pass in each section individually?
ReplyDeleteare u sure that all the answers are right?for the code of set B......plz give the explanation if possible for q.no 11,13,14,10,5,2,1,4,7,27,29,64,73,71......
ReplyDeleteblood group not match-answer is -O&B
ReplyDeleteq2 in set A and Q6 set B will have option 4. because the time taken for vertical motion is same because the vertical velocity is zero in the three case. note that we are neglecting the air drag
ReplyDeleteWhat is the selection criteria for csir net.....................Approximately how many marks are sufficent for qualifying net exam?

@Anonymous
ReplyDeleteThe answer is tA=tB=tC because the horizontal distances vary according to the horizontal component of velocity which depends on the kicking. but vertical component depends only on acceleration due to gravity.
