The value of electric potential at any point due to an electric dipole is

Which of the following is known as a fluid connective tissue?

$A$ beaker contains $200\, g$ of water. The heat capacity of the beaker is equal to that of $20\, g$ of water. The initial temperature of water in the beaker is $20^\circ C$. If $440\, g$ of hot water at $92^\circ C$ is poured into it,the final temperature (neglecting radiation loss) will be nearest to $^\circ C$.

The acute angle between the lines $6x^2 + 11xy - 10y^2 = 0$ is

On a temperature scale $Y$,water freezes at $-160^{\circ} Y$ and boils at $-50^{\circ} Y$. On this $Y$ scale,a temperature of $340 \ K$ is (in $^{\circ} Y$)

Consider the following statements $A$ and $B$ and identify the correct answer:
$A$. When a person walks on a rough surface,the direction of the frictional force exerted by the surface on the person is in the direction of his motion.
$B$. When a cycle is in motion,the force of friction exerted by the ground on the front wheel is in the backward direction.
