number 2 is correct

Explanation:

cementation as icons are deposited by fluids to form a compound that hardens looses sedimentary rocks .

Answer:

Compaction and cementation

Explanation:

Cementation: As ions are deposited by fluids to form a compound that hardens loose sedimentary rocks.

Compaction: As the density of sedimentary rocks on edge of them are forced together through sediments.

The coefficient of friction between a rider and the merry go round is 0.45 and the person is measured to be traveling at 20.0 RP

svlad2 [7]

The person must stand at a radius of 0.99 m

Explanation:

In order for the person to stand on the merry go round, the force of friction acting on the person must provide the centripetal force necessary to keep the person in uniform circular motion.

Therefore, we can write:

$\mu mg = m\omega^2 r$

where:

- the term on the left is the force of friction, and the term on the right is the centripetal force

$\mu = 0.45$ is the coefficient of friction

m is the mass of the person

$g=9.8 m/s^2$ is the acceleration of gravity

$\omega = 20 \frac{rev}{min} \cdot \frac{2\pi rad/rev}{60 s/min}=2.09 rad/s$ is the angular velocity

r is the radius of the circular path

Solving the equation for r, we find the radius at which the person must be standing:

$r=\frac{\omega^2}{\mu g}=\frac{(2.09)^2}{(0.45)(9.8)}=0.99 m$

How are weathering, erosion, and deposition related to the rock cycle

xenn [34]

Answer:

Erosion is the process by which natural forces move weathered rock and soil from one place to another. Gravity, running water, glaciers, waves, and wind all cause erosion. The material moved by erosion is sediment. Deposition occurs when the agents (wind or water) of erosion lay down sediment.
