The acceleration of gravity depends on the distance from
the center of the Earth. We use 9.8 m/s² for any place that's
on the Earth's surface, or reasonably close. The 11.5 meters
down into the well certainly qualifies.
The formula we want is:
Distance of fall = (1/2) · (acceleration) · (time)²
11.5 m = (1/2) (9.8 m/s²) (time)²
Divide each side
by 4.9 m/s² : (11.5m) / (4.9 m/s²) = time²
2.347 sec² = time²
time = √(2.347 sec²) = 1.53 seconds .
If the species has the resources and is fit in that area to survive.
Answer: find the answer in the explanation
Explanation:
The capillarity of water molecules is different from the mercury molecules.
What is capillarity ?
This is the tendency of a liquid substance to rise in a capillary tube.
Molecules water rises up in a harrow tubes because of the force of adhesion between the water molecules and the tube molecules is greater than the force of cohesion between the water molecules. This helps water to wet the tube and rise. While mercury which is also a liquid falls in a narrow tubes to level below the outside surface because the force of cohesion between the mercury molecules is greater than the force of adhesion between the mercury molecules and the tube molecules. Mercury does not wet.
