A boy has $60\, kg$ weight. He wants to swim in a river with the help of a wooden log. If relative density of wood is $0.6$. What is the minimum volume of wooden log? (Density of river water is $1000\, kg / m ^{3}$ )

A torque of $ {{10}^{-5}}Nm $ is required to hold a magnet at $ 90{}^\circ $ with the horizontal component of the earths magnetic field. The torque required to hold it at $ 30{}^\circ $ will be

The essential distinction between X-rays and $ \gamma - $ rays is that

A particle of mass $0.2\, kg$ tied at the end of a spring is being rotated along a vertical circle of radius $0.5\, m$ at critical speed of $5 \,m/s$. The tension T in the string at the highest point of its path is

The unit of universal gas constant is

Two bodies, $A$ (of mass $1\, kg$) and $B$ (of mass $3 \,kg$) are dropped from heights of $16\, m$ and $25 \,m$, respectively. The ratio of the time taken by them to reach the ground is:-

The correct option, if speed of gamma rays, $ x- $ rays and micro waves are $ {{\upsilon }_{g}},{{\upsilon }_{x}} $ $ \And \,{{\upsilon }_{m}} $ respectively will be:

We wish to see inside an atom. Assuming the atom to have a diameter of $100\, pm$, this means that one must be able to resolve a width of say $10\, pm$. If an electron microscope is used, the minimum electron energy required is about:

The waves which cannot travel in vacuum are:

The thermo-emf of a thermocouple is $25 \mu V/^\circ C$ at room temperature. A galvanometer of $40 \Omega $ resistance, capable of detecting current as low as $10^{-1} A, $ is connected with the thermocoupie. The smallest temperature difference that can be detected by this system is
