Who first suggested the idea of circular flow of genetic information?

The maximum value of $\sin (\cos (\tan x))$ is

$\int_0^1 x^{3/2} \sqrt{1-x} \, dx$ is equal to

$A$ rectangular loop has a sliding connector $PQ$ of length $2\ m$ and resistance $10\ \Omega$. It is moving with a speed $5\ m/s$ as shown in the figure. The set-up is placed in a uniform magnetic field of $3\ T$ directed into the plane of the paper. Find the three currents $I_1$,$I_2$,and $I$.

$A$ uniform cube of side $a$ and mass $m$ rests on a rough horizontal table. $A$ horizontal force $F$ is applied normal to one of the faces at a point that is directly above the centre of the face,at a height $\frac{3a}{4}$ above the base. The minimum value of $F$ for which the cube begins to tilt about the edge is (Assume that the cube does not slide):

What is the slope of the straight line for the graph drawn between $\ln k$ and $\frac{1}{T}$,where $k$ is the rate constant of a reaction at temperature $T$?
