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.

An electric Kettle is rated at 25 W. Calculate the quantity of heat generated in 2s

MatroZZZ [7]

Answer:

Energy consumed by the electric kettle in 9.5 min =Pt=(2.5×10

)×(9.5×60)=14.25×10

Energy usefully consumed =msΔT=3×(4.2×10

)×(100−15)=10.71×10

where s=4.2J/g

C= specific heat of water and boiling point temp=100

Heat lost =14.25×10

−10.71×10

=3.54×10

What are some indicators that a chemical reaction is occurring? Check all that apply.

VikaD [51]

Hi there! When a chemical Reaction happens, the tell tale signs are as listed:
~The chemical produces bubbles
~ The Chemical emits an odor
~ The liquid forms a solid(Precipitate)
~ There is a change of color
~ And last but not least a change in temperature!

Hope this can help! Good luck!

We know the frequency range of certain sounds are: 400-560 Hz, what are the ranges of wavelength in meters when the signal trans

Ksivusya [100]

Answer:

Range of wavelength will be $5.35\times 10^5m$ to $7.5\times 10^5m$

Explanation:

We have given range of frequency is 400-560 Hz

Speed of the light $c=3\times 10^8m/sec$

We have to find the range of the wavelength of signal transmitted

Ween know that velocity is given by $v=\lambda f$ , here $\lambda$ is wavelength and f is frequency

So for 400 Hz frequency wavelength will be $\lambda =\frac{c}{f}=\frac{3\times 10^8}{400}=7.5\times 10^5m$

And wavelength for frequency 560 Hz $\lambda =\frac{c}{f}=\frac{3\times 10^8}{560}=5.35\times 10^5m$

So range of wavelength will be $5.35\times 10^5m$ to $7.5\times 10^5m$

A projectile is fired from the origin (at y = 0 m) as shown in the diagram. The initial velocity

Viktor [21]

Answer:

-26 m/s.

Explanation:

Hello,

In this case, since the vertical initial velocity is 26 m/s and the vertical final velocity is 0 m/s at P, we compute the time to reach P:

$t=\frac{0m/s-26m/s}{-9.8m/s^2} =2.65s$

With which we compute the maximum height:

$y=26m/s*2.65s-\frac{1}{2}*9.8m/s^2*(2.65s)^2 \\\\y=34.5m$

Therefore, the final velocity until the floor, assuming P as the starting point (Voy=0m/s), turns out:

$v_f=\sqrt{0m/s-(-9.8m/s^2)*2*34.5m}\\ \\v_f=-26m/s$

Which is clearly negative since it the projectile is moving downwards the starting point.

Regards.

In a city grid, each block on the east-west streets is 100 meters long. Each block on the north-south streets is 20 meters long.

alex41 [277]

Answer:

72.1 m

Explanation:

Hello!

When the walker walks west, each block he walks will be of 100 m, so the walker walked 4*100m = 400 m west.

Similarly, when the walker walks south, he walks 20 meters per block, therefore, the walker walked 4*20 m = 80 m south.

Since the directions west and south are perpendicular, the distance between the start ad end point is:

d = √(400^2 + 80^2) m = 407.92 m

However the walker traveled 480 m

Therefore, the walker traveled 480 - 407.9 m = 72.1 m farther than the actual distance
