I think the answer is 3, population.
<span>The
answer is towards <span>the poles. This is because, at
the poles of the magnet, the magnetic field lines get closer together hence
indicating that the magnetic force is stronger here. The fields are closest
together at the center of the magnet and farthest at the outside side of the
magnet. </span></span>
<span>Scientists have obtained most of this information from natural geological activity.
</span>S-waves and p-waves are seismic waves- the waves of energy that travel through the Earth as a result of an earthquake .Both P- and S-waves travel easily through solids, but S-waves cannot pass through liquids, and they cannot pass through the outer core. Scientists know that Earth’s outer core is liquid because s-waves are not able to pass through it.<span> When an earthquake occurs there is a “shadow zone” on the opposite side of the earth where no s-waves arrive.
</span>So, one of the reasons <span>why scientists believe the outer core is liquid is the s-wave shadow zone.</span>
Answer:
-0.0426 m
Explanation:
-i / o = h' / h
-1.71 / 0.0237 = 3.04 /o
o = -0.042
1/o + 1/i = 1/f
1/(-0.042) + 1/(3.04) = 1/f
-23.81 +0.329 = 1/f
-23.481 = 1/f
f = -0.0426 m
