Answer:

ReCrystallization

Contact pressure causing grains to "grow" together.

It's a metamorphic process used to rearrange the atoms of the minerals in order to modify them in to the required form under the specific temperature and pressure. For example conversion of limestone into marble.

<em>Cementation:</em>

Precipitation of bonding agents between grains.

Cementation is the process in which the minerals in the form of fluid fills in spaces between the grains and binds them together upon crystallizing.

<em>Compaction:</em>

Increase in density due to weight of overburden.

Compaction as it's name indicate is the compaction of the sediments due to the heavy weight of the rocks which reduce their size and increase their density.

A rigid tank contains 1.80 moles of helium, which can be treated as an ideal gas, at a pressure of 27.3 atm. While the tank and
maria [59]

Answer:

Has been removed 1.458 moles.

Explanation:

n1= 1.8 mol

p1= 27.3 atm

p2= 5.2 atm

n2= ?

n2= n1 * p2/p1

n2= 0.342 moles

Δn= n1-n2

Δn= 1.458 moles

ANSWER FAST PLZZ!!
Dahasolnce [82]

Answer:

See the answer below

Explanation:

The two correct options are:

1. <em>The student traveled the fastest between 4 and 5 minutes</em>

<em>2. The average speed of the student is 4 meters per minute</em>

Between 4 and 5 minutes, the approximate distance of 7 meters covered by the student is the longest of all the distances covered per minute. Since speed is a measure of distance covered relative to time, <u>it means that the student traveled the fastest between these periods.</u>

<em>The average speed is calculated by dividing the total distance traveled by a body by the total time taken to cover the distance. </em>

From the graph:

Total distance covered = 20

Total time taken = 5

Average speed = 20/5 = 4 meters per minute

<em>All the remaining conclusions are incorrect or indeterminate going by the information on the graph.</em>

hoa [83]

Answer:

k_2 =3826.08 J

K_1 = 4973.91 J

Explanation:

from conservation of momentum principle

0 = m_1v_1+m_2v_2

we know that kinetic energy is given as

k_1 = \frac{1}{2} m_1v_1^2

k_2 = \frac{1}{2} m_2v_2^2

we have v_1 =-1.3v_2, m_2 = 1.3m_1

therefore k_1 =\frac{1}{2} (\frac{m_2}{1.3})(-1.3v_2)^2 = 1.3k_2

now

k_1+k_2 = 8800

1.3k_2 +k_2 =8800

k_2 =3826.08 J

K_1 = 4973.91 J

A driver starts his parked car and within 4.6 seconds, reaches a velocity of 15 m/s. What is his acceleration?
myrzilka [38]
Answer: 6.
All of the numbers in every row and column add up to 15! (Also, 6 is the only number not represented out of numbers 1 through 9.)
And to the representation to his problem you can clear,y see that 4.6 seconds is actully the the time of the whole parking. so if you just do a simple equation... 4.6x10p/2x15/10x2 would get your answer to 6
