An ideal gas is heated at constant pressure so as to triple its volume. Find the increased temperature of the gas if initial temperature of gas is \(27^{\circ}\) C.

A point particle of mass \(0.1 \mathrm{~kg}\) is executing SHM of amplitude \(0.1 \mathrm{~m}\). When the particle passes through the mean position, its \(\mathrm{KE}\) is \(8 \times 10^{-3} J\). The equation of motion of this particle, if its initial phase of oscillation is \(45^{\circ}\).

Given the resistances of \(1 \Omega, 2 \Omega, 3 \Omega\), how will be combine them to get an equivalent resistance of:

One requires \(11eV\) of energy to dissociate a carbon monoxide molecule into carbon and oxygen atoms. The minimum frequency of the appropriate electromagnetic radiation to achieve the dissociation lies in:

What is the shortest wavelength present in the Paschen series of spectral lines?

A uniform chain of length \(2 \mathrm{~m}\) is kept on a table such that a length of \(60 \mathrm{~cm}\) hangs freely from the edge of the table. The total mass of the chain is \(4 \mathrm{~kg}\). What is the work done in pulling the entire chain on the table ?

A block of mass \(2\) kg rests on a rough inclined plane making an angle of \(30^\circ\) with the horizontal. The coefficient of static friction between the block and the plane is \(0.7\). The frictional force on the block is:
