Some hummingbirds beat their wings more than 50 times per second. A scientist is measuring the time it takes for a hummingbird to beat its wings once. Which SI-base unit (i.e., fundamental unit) should the scientist use to describe the measurement?

Answer:

millisecond

Explanation:

Time is measured in seconds in the SI system. The scientist will measure the time it takes to complete one flap of the wings. In the SI system the use of prefix makes it easier to describe the value. It is as follows

[tex]1\ ns=10^{-9}\ s[/tex]

[tex]1\ \mu s=10^{-6}\ s[/tex]

[tex]1\ ms=10^{-3}\ s[/tex]

[tex]1\ cs=10^{-2}\ s[/tex]

Here, the wings flap so fast that the millisecond should be used.
