How are stop watches useful to us? |
|
Answer» 1. We use stop clocks in the laboratory to measure time taken for completion of chemical reactions, time taken by the pendulum for one oscillation etc. 2. Apart from this, they also help us to measure the time in races and games very accurately even to the extent of fraction of seconds. 3. Now-a-days, we use electronic clocks, digital clocks, and stop clocks in mobile phones to measure time. 4. Stop clocks are used to measure shorter time intervals between two events accurately. |
