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.

A concrete block is hung from an ideal spring that has a force constant of 100 N/m . The spring stretches 0.129 m .A- What is th

madam [21]

Answer:

1.31498 kg

0.72050 s

Explanation:

m = Mass of block

g = Acceleration due to gravity = 9.81 m/s²

k = Spring constant = 100 N/M

x = Displacement = 0.129 m

The force balance is

$mg=kx\\\Rightarrow m=\dfrac{kx}{g}\\\Rightarrow m=\dfrac{100\times 0.129}{9.81}\\\Rightarrow m=1.31498\ kg$

The mass of the block is 1.31498 kg

Time period is given by

$T=2\pi\sqrt{\dfrac{m}{k}}\\\Rightarrow T=2\pi\sqrt{\dfrac{1.31498}{100}}\\\Rightarrow T=0.72050\ s$

The period of oscillations is 0.72050 s

The time period does not depend on the acceleration due to gravity. It varies with the mass and the spring constant.

Hence, the time period would be the same

The period of a simple pendulum is 3.5 s. The length of the pendulum is doubled. What is the period T of the longer pendulum?

Rudik [331]

Answer:

Explanation:

T = 2π√(L/g)

If you increase L to 2L, the period is increased by a factor of √2

T = 3.5√2 ≈ 4.9 s

A rolling ball has an initial velocity of 1.6 meters per second. if the ball has a constant acceleration of 0.33 meters per seco

lukranit [14]

We have:

Initial velocity (u) = 1.6 m/s
Constant acceleration (a) = 0.33 m/s²
Time (t) = 3.6 sec

There are five constant acceleration equations that would help us to find the velocity:

$v=u+at$
$s=ut+ \frac{1}{2}at^2$
$s= \frac{1}{2}(u+v)t$
$v^2=u^2+2as$
$s=vt- \frac{1}{2}at^2$

Since we have $u, a, t$ and we want $v$
We will use the first formula $v=u+at$

$v=1.6+(0.33)(3.6)$
$v= 2.788$ m/s

3000 N is exerted for 4.0 seconds on a 9500 kg object.<br><br> What is the change in momentum?

WARRIOR [948]

Force is the change in momentum over a specific time. The change of momentum is therefore the force multiplied by the time that the force acts, so 3000x4.0=12000 N s=12000 kg m/s
