Question

The earth completes one rotation from west to east on its axis in ---------.
A) 23 hours, 56 minutes, 4.09 seconds.
B) 23 hours, 59 minutes, 4.09 seconds.
C) 23 hours, 58 minutes, 4.09 seconds.
D) 23 hours, 57 minutes, 4.09 seconds.

Answer 1

Hint: Rotation means the circular movement of an object around the middle. It's possible to rotate different shapes by an angle round the center point. In three-dimensional shapes, the objects are often rotated about an infinite number of imaginary lines referred to as rotational axes.

Complete answer:
As we all know, it takes exactly 24 hours for the Sun to return to an equivalent spot within the sky, which might seem obvious. But it takes: 23 hours, 56 minutes, 4.09 seconds, to finish one rotation from west to east on its axis.

24 hours is what we expect of as being an entire day, and therefore the time it takes to transition from day to nighttime and back again. But in fact, it actually takes the world 23 hours, 56 minutes, and 4.09 seconds to rotate once on its axis compared to the background stars.

Well, that might be because the world is orbiting around the Sun, completing one orbit in only over three hundred and sixty five days. If you divide 24 hours by three hundred and sixty five days , you’ll see that you’re left with about 4 minutes per day. In other words, the world rotates on its axis, but it’s also orbiting around the Sun, therefore the Sun’s position within the sky catches up by 4 minutes every day .

Hence, Option A is the correct answer.

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