use avogad law... at identical temp and pressure, equal amounts (in moles) of a gas occupy equal volumes... So the ratio of their weights will be the ratio of their molecular weights ie 12+32 : 32+32= 44:64=11:16=0.6875

How is down southwards??? Down means towards the centre of the earth!

Acc to Rayleigh Jeans law, Energy density is proportional to 1/λ4. It implies that even at room temp, we are bombarded with large amounts of short-wavelenght radiation which is an absurd result, called UV catastrophe. PS: AFAIK, its not in the JEE syllabus.

a projectile thrown to the west! Acceleration will be downward, not towards N, S, E or W. At the topmost pt, the inst velocity will point exactly west.

Although ur quest makes no sense if read literally, I think I know what ur trying to ask... Is the answer 5/4 ie dielectric const=1.25

for 2 reasons- under these conditions, the molecules are spread widely apart- intermolecular forces are negligible - The volume occupied by the molecules themselves is negligible compared to the volume occupied by the gas.

Use the equation for projectile: y= x tan60 +g x2sec260/202 .......................................(1) Plug in the values(y=5, trigo values) and solve the quadratic for x. Now differentiate eqn (1) wrt x and put the values. the value of y' will be the slope. NB: you will get two values of x

If u pull with a jerk, the lower string will break first, because the mass tends to stay where it is to some extent due to inertia... when u pull slowly, the top string will break cuz of more tension.

When we say a capacitor completely blocks DC, we mean it does so in the steady state, not in the transition phase.

Lets see who can figure this one out! Why is it easy to balance on a moving bicycle while it is difficult to balance on a stationary one.(Without stands, and ur legs not touching d ground!)

In org, our sir had taught us d song for priority of funct groups: Carboxylic sulphonic anhydride celebrated easter with halide and amide. Nitrile and aldehyde could not attend because ketone consumed alcohol and shouted mi ke ky therefore in decreasing priority Carboxylic acid Sulphonic Acid Acid Anhydride Ester (from 'easter' in the song) Acid Halide Amide Nitrile Aldehyde Ketone Alcohol amines alkenes alkynes Hope u get it :)

i think its the 2nd one that will b faster. Its basically β elimination. by markonikoff rule, the middle Hs will b preferably removed... in 1st case, this is difficult, as the middle β carbon is sp2 hybridized.

uv light causes free radicals of chlorine 2 b formed. These free radicals can only attach to the side chain(methyl group in this case) and not to the benzene ring..

tan π/2 is undefined as x tends to π/2 from the left, tanx tends to ∞ as x tends to π/2 from the right, tanx tends to -∞ undefined means, 'it has no exact value' ∞ means bigger than any number you can think of....

^ No, the questions, especially of the exercise is higher dan bitsat. But I highly recommend that you solve them, at least as many as you can. Solving tough problems makes you feel that the moderately difficult ones are easy ;) And Solve ALL the objectives, they are purely concept based and you can expect such questions to come in your bitsat :)
