Two ideal polyatomic gases at temperatures T₁ and T₂ are mixed so that there is no loss of energy. If F₁ and F₂, m₁ and m₂, n₁ and n₂ be the degrees of freedom, masses, number of molecules of the first and second gas respectively, the temperature of mixture of these two gases is:

An AC current is given by I = I₁sinωt + I₂cosωt. A hot wire ammeter will give a reading:

For what value of displacement the kinetic energy and potential energy of a simple harmonic oscillation become equal?

When two soap bubbles of radii a and b (b > a) coalesce, the radius of curvature of common surface is:

A Carnot's engine working between 400 K and 800 K has a work output of 1200J per cycle. The amount of heat energy supplied to the engine from the source in each cycle is:

A solenoid of 1000 turns per meter has a core with relative permeability 500. Insulated windings of the solenoid carry an electric current of 5 A. The magnetic flux density produced by the solenoid is: (permeability of free space = 4π*10^-7H/m)

A polyatomic ideal gas has 24 vibrational modes. What is the value of γ ?

A modern grand - prix racing car of mass m is traveling on a flat track in a circular arc of radius R with a speed v. If the coefficient of static between the tyres and the track is µs, then the magnitude of negative lift F acting downwards on the car is : (Assume forces on the four tyres are identical and g = acceleration due to gravity)
