Question

explain any three conventional methods to measure length

Answer 1

• Length can be measured by a linear scale rod. The scale is kept with any mark matching the starting edge of object. We will get a mark at the ending point of object.

Final mark-Initial mark= the length of object .

• Mass can be measured by a common balance where weights are placed in one pan and the required object in another and when the support comes to an equilibrium, the Mass is known.

• Time can be measured by a stop watch. The button needs to be pressed before the starting if event and again as the event ends. For more accurate measurements, instruments like chronometer can be used.
