Which of the measuring tools shown
is a digital stopwatch? Tool (A), tool (B), or tool
(C).
Tool (A) has a clock face with
hands and a swinging pendulum down below, both analog features. It is a pendulum clock. Looking now at tool (B), we see
that there are no digital interfaces at all nor any interfaces really. There is just some glass and some
sand. This is an hourglass. Unlike the first two tools which
have an analog pendulum and analog sand, tool (C) has a digital display. It is the digital stopwatch. So, out of these measuring tools
shown, (C) is the digital stopwatch.
