The mmsanotherstage2019.com should be D due to the fact that A,B,andC are showing the exact time in which it took for the event while D is vary general on the time the event stoped

mmsanotherstage2019.com:

Least precise recorded time is 48.9 seconds.

You are watching: Timers at a swim meet used four different clocks to time an event

Explanation:

Here, we need to write the recorded time that is least precise. The given options are (a) 48.9107 s (b) 48.91 s (c) 48.910 s (d) 48.9 s. The precision in any measurement is defined as closeness in any measurement.

First option is most precise as it is precised to four decimal places. Second option is precised to two decimal places. Third option is precised to 3 decimal places. But in option fourth, the recorded time is precised to one decimal place.

Hence, the correct option is (d).

Restoring Force

Explanation:

The distance from one crest to the next is a wave"s wavelength. This kind of force pulls a system back to equilibrium: restoring force. Sound waves are an example of this kind of wave: longitudinal wave. The amplitude of two waves will cancel when destructive interference occurs.
