Answer:
3.6m
Explanation:
if you are at a building that is 46m above the ground, and the professor is 1.80m, the egg must fall:
46m - 1.80m = 44.2m
the egg must fall for 44.2m to land on the head of the professor.
Now, how many time this takes?
we have to use the following free fall equation:

where
is the height,
is the initial velocity, in this case
.
is the acceleration of gravity:
and
is time, thus:

clearing for time:

we know that the egg has to fall for 44.2m, so
, and
, so we the time is:

Finally, if the professor has a speed of
, it has to be at a distance:

and t=3.002s:

so the answer is the professor has to be 3.6m far from the building when you release the egg

Answer:
Explanation:
A magnet has a magnetic field around it which originates at the north pole and enters through the south pole.
In a magnet, like poles will repel each other and unlike poles will attract.
- The north pole of one magnet will repel another north pole of another magnet.
- North pole of one magnet will attract the south pole of another magnet.
- This is the law of attraction and repulsion of magnet.
