What is a stopwatch what is the least count of mechanical stopwatch?

What is a stopwatch what is the least count of mechanical stopwatch?

The least count of a mechanical stopwatch we have used in the laboratory is 0.1 seconds.

What does a stopwatch count?

A stopwatch is a timepiece designed to measure the amount of time that elapses between its activation and deactivation.

What is the least count of protractor?

The least angle a protector can measure is called least count of a protractor. It is 1 degree in normal protractors (as there are 10 divisions after every 10 degrees).

What is the least count of Vernier bevel protractor 1 point 10 5 5 10?

Explanation: The least count of bevel protractor is 5′.

Which is the least count of a stop watch?

The least count of a stop – watch is (1/5) s . The time of 20 oscillations of a pendulum is measured to be 25 s . What is the maximum percentage error in this measurement? The least count of a stop-watch is (1/5) s. The time of 20 oscillations of a pendulum is measured to be 25 s. What is the maximum percentage error in this measurement?

What is the absolute uncertainty of a stopwatch?

The golden rule while dealing with least counts is that the absolute uncertainty will always be 50% of the least count of a measuring device. Therefore, we can say that the absolute uncertainty of your stopwatch is ±0.1 seconds.

Which is the least count of time period?

Time period = 25/20 = 1.25 sec Least count of watch = 0.2 sec The measurement of time period 1.25 the measuring watch can measure upto 0.2 s thus the watch can measure 1.2 s but the uncertainity remains in the 0.05 s. 1.25 s= 1.2+0.05

How does the center hand work on a stopwatch?

Typically the center hand will be used for stopwatch functions, while subdials may indicate seconds, stopwatch minutes and hours and (in some quartz chronographs) tenths or hundredths of a second.
