Answer:
<em>B. 68.6m</em>
Explanation:
<u>Free Fall Motion
</u>
When a body is left to move in the air with no friction, the motion is ruled only by the force of gravity. The vertical distance a body travels in the air after a time t is
.

We know the egg takes 3.74 seconds to reach the ground. The height it was launched from is


The closest correct option is
B. 68.6m
A rotation is when the earth turns in a circle on it's axis. A revolution is the oblong path the the earth is constantly moving in around the sun. A revolution takes 365.25 days where as a rotation happens in 24 hours. <span />
Magnetic stripes on the sea floor
Explanation:
The observation of magnetic stripes patterns at the region of the Mid-Atlantic Ridge galvanized the evidence that sea floor spreading has been on for several millions of years.
- Geomagnetic field of the earth is similar to that of bar magnet having the north and south pole.
- It originates from the movement of iron-nickel within the outer core.
- This geomagnetic field causes the magnetization of magnetic minerals in rock.
- When freshly formed magma is brought to the surface at the mid oceanic ridge area, the prevailing magnetic field causes the magnetic minerals in the magma to cool in such a way that they align their domains to that of the field.
- The magnetic field of the earth can reverse and take different geometry. Sometimes, its intensity is very strong and at other times it is weak.
- The magnetic minerals in melts bear these records.
- As new materials are brought up, they get magnetized.

Well, I'm not sure right now that it actually does.
But if it does, that's because the sun is about 400 times
FARTHER from the Earth than the moon is.
