Question

1) The earth’s rotation has enabled us to measure time in terms of days. *
true or false

Answer 1

Answer: Rotational Velocity:

Explanation: But much like measuring a day, the Earth's rotation can be measured in one of two different ways. Earth's rotation period relative to the fixed stars is known as a “stellar day”, which is 86,164.098903691 seconds of mean solar time (or 23 hours, 56 minutes and 4.0989 seconds).

Answer 2

$\large\red\mapsto$ True

Explanation:

At any given moment, we are all moving at a speed of about 1,674 kilometers an hour, thanks to the Earth's rotation, By definition, the Earth's rotation is the amount of time that it takes to rotate once on its axis. This is, apparently, accomplished once a day – i.e. every 24 hours.
