Mine tailings be stored and disposed of carefully since they
contain a lot of chemicals that are very toxic that leaches into aquifers, and
they also runoff in the rainwater into streams and lakes.
Tailings, also
called mine <span>dumps, culm dumps, slimes, tails, refuse,
leach residue or slickens, are the materials left over after the process of
separating the valuable fraction from the uneconomic fraction (gangue) of an
ore.</span>
High ocean temperatures of above 26.5 degrees Celsius and coriolis effect( deflection of winds create spiraling motion)
Answer:
a. 8p
Explanation:
We are given that
Radius of hollow sphere , R1=R
Density of hollow sphere=
After compress
Radius of hollow sphere, R2=R/2
We have to find density of the compressed sphere.
We know that
Therefore,
Volume of sphere=
Using the formula
Hence, the density of the compressed sphere=
Option a is correct.
Answer:
Centrifugal force
Explanation:
The reacting force that is equal to and opposite in the direction to the centripetal force and tends to fling air out of the center of rotation of High and Low pressure systems is called centrifugal force.
Centrifugal force is force that causes an object moving in a circular path to move out and away from the center of it's path, it always centripetal force and the force is imaginary, which can only be felt and not seen.
