Two conducting circular loops of radii $R_1$ and $R_2$ are placed in the same plane with their centres coinciding. If $R_1 >> R_2$, the mutual inductance $M$ between them will be directly proportional to
The incorrect statement among the following is :
The final proof for DNA as the genetic material came from the experiments of:
Identify the correct statements from the following: (a) $CO_2(g)$ is used as refrigerant for ice-cream and frozen food. (b) The structure of $C_{60}$ contains twelve six carbon rings and twenty five carbon rings. (c) ZSM-5, a type of zeolite, is used to convert alcohols into gasoline. (d) CO is colorless and odourless gas.
For the given circuit, the input digital signals are applied at the terminals $A$, $B$ and $C$. What would be the output at the terminal $y$?
Statement I : Acid strength increases in the order given as $HF << HCl << HBr << HI$. Statement II : As the size of the elements F, Cl, Br, I increases down the group, the bond strength of HF, HCl, HBr and HI decreases and so the acid strength increases. In the light of the above statements, choose the correct answer from the options given below.
Satellite DNA is a useful tool in:
Identify the incorrect statement.

If Adenine makes 30% of the DNA molecule, what will be the percentage of Thymine, Guanine and Cytosine in it?
A copper wire of length $10\text{ m}$ and radius $\frac{10^{-2}}{\sqrt{\pi}}\text{ m}$ has electrical resistance of $10\ \Omega$. The current density in the wire for an electric field strength of $10\text{ V/m}$ is
The potential energy of a long spring when stretched by $2 \text{ cm}$ is $U$. If the spring is stretched by $8 \text{ cm}$, potential energy stored in it will be
Two charged spherical conductors of radius $R_1$ and $R_2$ are connected by a wire. Then the ratio of surface charge densities of the spheres ($\sigma_1/\sigma_2$) is
A particle of mass '$m$' is projected with a velocity $v = kv_e$ ($k < 1$) from the surface of the earth. ($v_e$ = escape velocity). The maximum height above the surface reached by the particle is
When the centromere is situated in the middle of two equal arms of chromosomes, the chromosome is referred as :
For the velocity-time graph shown in the figure, the distance covered by the body in the last two seconds of its motion is what fraction of the total distance covered by it in all the seven seconds?
Which chromosome in the human genome has the highest number of genes?
A ball of mass $0.15 \text{ kg}$ is dropped from a height $10 \text{ m}$, strikes the ground and rebounds to the same height. The magnitude of impulse imparted to the ball is ($g = 10 \text{ m/s}^2$) nearly
The following solutions were prepared by dissolving 10 g of glucose ($C_6H_{12}O_6$) in 250 ml of water ($P_1$), 10 g of urea ($CH_4N_2O$) in 250 ml of water ($P_2$) and 10 g of sucrose ($C_{12}H_{22}O_{11}$) in 250 ml of water ($P_3$). The right option for the decreasing order of osmotic pressure of these solutions is :
