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 |
D. | Tidal Volume | iv. | Total volume of air expired after normal inspiration |
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 bob of heavy mass \(m\) is suspended by a light string of length \(l\). The bob is given a horizontal velocity \(v_0\) as shown in figure. If the string gets slack at some point P making an angle \( \theta \) from the horizontal, the ratio of the speed \(v\) of the bob at point P to its initial speed \(v_0\) is :
