A glass sheet 12xx10^(-3) mm thick (mu_(g)=1.5) is placed in the path of one of the interfering beams in a Yongs's double slit interference arrangement using monochromatic light of wavelenght 6000 A. If the central bright fringe shifts a distance equal to width of 10 bands. What is the thickness of the sheet of diamond of refractive index 2.5 that has to be introduced in the path of second beam to bring th ecentral bright fringe to original position?

An examination was held during the 2 weeks of April 3rd-Sunday to 16th Saturday. There was 1 paper for the six subjects - Physics, Chemistry, Biology, Maths, English and Hindi. Only 1 paper per day No exam on Saturdays and Sundays and Holiday on April 5th. Only 3 exams were there in a week. Chemistry was before Biology and Maths was on the next day of Hindi. The day on which the paper of biology and maths were held was the same, while that for chemistry and physics was also the same. There was no exam for 3 days between Physics and the exam prior to it. Hindi exam on Tuesday and one exam between Hindi and English exam. There was at least a gap of one day between any 2 science paper. Which of the following exam was held on April 12th ?

Over the past 200 working days, the number of defective parts produced by a machine is given in the following table : |{:("Number of","0 1 2 3 4 5 6 7 8 9 10 11 12 13"),("defective parts",),("Days","50 32 22 18 12 12 10 10 10 8 6 6 2 2"):}| Determine the probability that tomorrow's output will have : (i) no defective part. (ii) at least one defective part, (iii) not more than 5 defective parts, (iv) more than 13 defective parts.

A horizontal tube having cross sectional area A_(1)=10cm^(2) has a venturi connected to it having cross sectional area A_(2)=4 cm^(2) . A moanometer, having mercury as its liquid is connected to be has uniform cross section and it has a horizontal part of lenght L=10cm. When there is no flow in the tube the height of mercuty column in both vertical arms is H=12cm. calculate the minimum flow rate (in m^(3)//s ) of air through the tube if it is required that the entire amount of mercury move to one vertical arm of the manometer. Gives, density of Hg=13.6xx10^(3)kgm^(3) , density of air=1.2 kg m^(-3) .
