A, B and C are voltmeters of resistance R, 1.5 R and 3R respectively as shown in the figure. When some potential difference is applied between X and Y, the voltmeter readings are VA, VB and V respectively. Then :
Three blocks A, B and C of masses 4 kg, 2 kg and 1 kg respectively, are in contact on a frictionless surface, as shown. If a force of 14 N is applied onthe 4 kg block, then the contact force between A and B is :
If in a p-n junction, a square input signal of 10 V is applied as shown,
If energy (E), velocity (V) and time (T) are chosen as the fundamental quantities, the dimensional formula of surface tension will be :
Figure below shows two paths that may be taken by a gas to go from a state A to a state C.
The ratio of the specific heats Cp/Cv =λ in terms of degrees of freedom (n) is given by :
