| A. | Residual Volume | i. | Maximum volume of air that can be breathed in after forced expiration |
| B. | Vital Capacity | ii. | Volume of air inspired or expired during normal respiration |
| C. | Expiratory Capacity | iii. | Volume of air remaining in lungs after forcible expiration |

A. Residual Volume: The volume of air remaining in the lungs even after forceful expiration. A-III
B. Vital Capacity: The maximum volume of air that can be exhaled after a maximum inhalation. It represents the largest volume of air that can be moved in or out of the lungs. B-I
C. Expiratory Capacity: The total volume of air that can be expired after a normal inspiration. This includes the tidal volume and the expiratory reserve volume. C-IV
D. Tidal Volume: The volume of air inspired or expired during a normal breath. D-II
A sphere of radius R is cut from a larger solid sphere of radius 2R as shown in the figure. The ratio of the moment of inertia of the smaller sphere to that of the rest part of the sphere about the Y-axis is : 
AB is a part of an electrical circuit (see figure). The potential difference \(V_A - V_B\), at the instant when current \(i = 2\) A and is increasing at a rate of 1 amp/second is:
Three identical heat conducting rods are connected in series as shown in the figure. The rods on the sides have thermal conductivity 2K while that in the middle has thermal conductivity K. The left end of the combination is maintained at temperature 3T and the right end at T. The rods are thermally insulated from outside. In steady state, temperature at the left junction is \(T_1\) and that at the right junction is \(T_2\). The ratio \(T_1 / T_2\) is
