iv. Normally both M and S coincide with position o2f zero. v. The button is pressed and released for recording the time interval between the start ‘B’ and stop of the vi. By pressing and releasing button the needle, of stopwatch returned at zero and ready for next ‘B’ fresh reading. MEASURING CYLINDER: Construction: i. It is made-up of ii. A scale in cubic centimeter or millimeter printed on it. iii. It is used to find volume of liquids. iv. When we pour liquid into the cylinder, the level of liquid in the cylinder is noted. v. We should keep the eye in level with the bottom of the meniscus of the liquid in order to read the volume correctly. vi. The liquid surface and the cylinder must be on a horizontal table. Q14. Define the following: i. Directly Proportional ii. Inversely Proportional iii. Proportional Constant Ans. DIRECTLY PROPORTIONAL Such relation between two physical quantities in which one is increased other is also increased, and similarly when one is decreased, the other is decreased, is called Directly Proportional. Example: V T ∞ This equation shows the relation of directly proportional between Volume and Absolute Temperature.
