One mole of an ideal diatomic gas undergoes atransition from A to B along a path AB as shownin the figure,
The change in internal energy of the gas during the transition is :
An electron moving in a circular orbit of radius rmakes n rotations per second. The magnetic fieldproduced at the centre has magnitude :
The interference pattern is obtained with two coherent light sources of intensity ratio n. In the interference pattern, the ratio Imax-Imin/Imax+Imin will be
An air bubble in a glass slab with refractive index 1.5 (near normal incidence) is 5 cm deep when viewed from one surface and 3 cm deep when viewed from the opposite face. The thickness (in cm) of the slab is
Two identical glass (μg = 3/2) equiconvex lenses of focal length f each are kept in contact. The space between that two lenses in filled with water (μw = 4/3). The focal length of the combination is
A 100 Ω resistance and a capacitor of 100 Ω reactance are connected in series across a 220 V source. When the capacitor is 50% charged, the peak value of the displacement current is
