Question

Digital stopwatches show reading up to:
(A) $1$ decimal place
(B) $2$ decimal place
(C) $3$ decimal place
(D) $4$ significant figures

Answer 1

A handheld timepiece is a stopwatch designed to measure the amount of time between its activation and deactivation. As in a sports stadium, a large digital version of a stopwatch designed for viewing at a distance is called a stop clock. In manual timing, a person pressing a button starts and stops the clock.

Complete step by step answer:
Stopwatches are watches which measure the timing of events. The stopwatch tells the person how long it takes to perform a certain function instead of telling one the time of day. Multiple events can time certain stopwatches. Along with the total time of the event, some stopwatches can time parts of the event. The stopwatch includes buttons, such as starting, stopping, and split timing, to perform certain functions. Other functions, such as an alarm or a calendar function, can also be used for various stopwatches.
A digital stopwatch shows reading up to $2$ decimal places.

Correct option is (B)

Additional Information: The operation of a stopwatch is to count the time of an event accurately. The timers are simple to use and you need to press a start button to start the count. The time stops on the stop button once the event is over. On the face of the wristwatch, as well as other common data, such as time and date, the time covered by the recorded event will be shown. To count another event or event, you can restart the stopwatch. There are wristwatches with a chronometer, but models that can be hung on the neck or carried in the pocket are also available.

Note: Both starting and stopping are triggered automatically by sensors at a fully automatic time. Two buttons on the case traditionally control the timing functions. The timer starts running by pressing the top button and stops it by pressing the button a second time, leaving the elapsed time displayed. Then, pressing the second button resets the stopwatch to zero. It also uses the second button to record split times or lap times.
