Answer:

Explanation:

For sediment to become sedimentary rock, it has to undergo the following; burial, compaction, and cementation. And the process through which all these takes place is called cementation. The formation of sedimentary rock may take millions of years.

Answer:

A sediment has to undergo TRANSPORTATION, DEPOSITION, COMPACTION AND CEMENTATION in order for it to become a sedimentary rock

Explanation:

Sedimentary rocks are formed when rocks undergo the process of weathering(breaking down) and the rock particles or sediments are transported by either water, air to particular area where they are deposited layers by layers in order form a sedimentary rock.

Sediments undergo the processes of Transportation, Deposition,Compaction and Cementation in order to form Sedimentary rocks.

a. Transportation: This is the process after weathering of the rocks, whereby the rock particles are transported or moved by either water, air or wind, ice to other places.

b. Deposition: This is the process whereby the transported sediments are laid down in the form of layers on land.

c. Compaction can be defined as the process in sedimentary rock formation where the sediments are compacted or squeezed together leading to a reduction in the pore spaces between the sediments due to the pressure accumulated by the weight of the layers and layers of sediments.

d. Cementation is a process in Sedimentary rock formation where the are attached together by the minerals contained in the water found in the pore spaces located in the sediments.

Marissaâs car accelerates uniformly at a rate of +2.60 m/sÂ². How long does it take for Marissaâs car to accelerate from a speed

DIA [1.3K]

Answer:

The time taken by the car to accelerate from a speed of 24.6 m/s to a speed of 26.8 m/s is 0.84 seconds.

Explanation:

Given that,

Acceleration of the car, $a=+2.6\ m/s^2$

Initial speed of the car, u = 24.6 m/s

Final speed of the car, v = 26.8 m/s

We need to find the time taken by the car to accelerate from a speed of 24.6 m/s to a speed of 26.8 m/s. The acceleration of an object is given by :

$t=\dfrac{v-u}{a}$

$t=\dfrac{(26.8-24.6)\ m/s}{2.6\ s}$

t = 0.84 seconds

So, the time taken by the car to accelerate from a speed of 24.6 m/s to a speed of 26.8 m/s is 0.84 seconds. Hence, this is the required solution.

Step2247 [10]

Answer:

A) 60%

B) p2 = 1237.2 kPa

v2 = 0.348 m^3

C) w1-2 = w3-4 = 1615.5 kJ

Q2-3 = 60 kJ

Explanation:

A) calculate thermal efficiency

Л = 1 - $\frac{Tl}{Th}$

where Tl = 300 k

Th = 750 k

hence thermal efficiency ( Л ) = [1 - ( 300 / 750 )] * 100 = 60%

B) calculate the pressure and volume at the beginning of the isothermal expansion

calculate pressure ( P2 ) :

= P3v3 = mRT3 ----- (1)

v3 = 0.4m , mR = 2* 0.287, T3 = 750

hence P3 = 1076.25

next equation to determine P2

Qex = p3v3 ln( p2/p3 )

60 = 1076.25 * 0.4 ln(p2/p3)

hence ; P2 = 1237.2 kpa

calculate volume ( V2 )

p2v2 = p3v3

v2 = p3v3 / p2

= (1076.25 * 0.4 ) / 1237.2

= 0.348 m^3

C) calculate the work and heat transfer for each four processes

work :

W1-2 = mCv( T2 - T1 )

= 2*0.718 ( 750 - 300 ) = 1615.5 kJ

W3-4 = 1615.5 kJ

heat transfer

Q2-3 = W2-3 = 60KJ

Q3-4 = 0
