Nitrogen is a diatomic gas. Its molar specific heat a constant volume

1.	Nitrogen is a diatomic gas. Its molar specific heat a constant volume is very nearly:
Answer» `(5R)/(2)` `(7R)/(2)` `(3R)/(2)` (a) and (b) (c) depending on the temperature. Solution :We know that `C_(v) =(F)/(2) RT` and degree of freedom for a DIATOMIC gas varies with temperature `f=3" for "T le 70 k`. `f=5" for "250 k le T le 750 k` `f=7" for "T GE 750 k` Thus, CORRECT choice is (d).

A wire is bent to form a semicircle of the radius a. The wire rotates about its one end with angular velocity omega . Axis of rotation is perpendicular to the plane of the semicircle . In the space , a uniform magnetic field of induction B exists along the aixs of rotation as shown in the figure . Then -
A massless non conducting rod AB of length 2l is placed in uniform time varying magnetic field confined in a cylindrical region of radius (R gt l) as shown in the figure. The center of the rod coincides with the centre of the cylin- drical region. The rod can freely rotate in the plane of the Figure about an axis coinciding with the axis of the cylinder. Two particles, each of mass m and charge q are attached to the ends A and B of the rod. The time varying magnetic field in this cylindrical region is given by B = B_(0) [1-(t)/(2)] where B_(0) is a constant. The field is switched on at time t = 0. Consider B_(0) = 100T, l = 4 cm(q)/(m) = (4pi)/(100) C//kg. Calculate the time in which the rod will reach position CD shown in the figure for th first time. Will end A be at C or D at this instant ?
