The steps in the formation of sedimentary rocks are listed below in an incorrect order.

Arlecino [84]

The first step in the formation of sedimentary rock is weathering of preexisting rocks. The second step is transport of the weathering products. The third step is deposition of the material. And at the end there is compaction and cementation of the sediment to form a rock.
According to this, the following shows the correct order of steps in the formation of sedimentary rocks:
C. <span>1, 4, 3, 2
</span>Rocks are weathered.Small pieces of rocks are carried by water.They are deposited in layers.<span>The sediments are compacted together.</span>

A constant force of 3.2 N to the right acts on a 18.2 kg mass for 0.82 s. (a) Find the final velocity of the mass if it is initi

zheka24 [161]

Explanation:

The given data is as follows.

F = 3.2 N, m = 18.2 kg,

t = 0.82 sec

(a) Formula for impulse is as follows.

I = Ft = $\Delta P$

Ft = $m(v_{f} - v_{i})$

or, $v_{f} = \frac{Ft}{m} + v_{i}$

Putting the given values into the above formula as follows.

$v_{f} = \frac{Ft}{m} + v_{i}$

= $\frac{3.2 \times 0.82}{18.2} + 0$

= 0.144 m/s

Therefore, final velocity of the mass if it is initially at rest is 0.144 m/s.

(b) When velocity is 1.85 m/s to the left then, final velocity of the mass will be calculated as follows.

Ft = $m(v_{f} - v_{i})$

or, $v_{f} = \frac{Ft}{m} + v_{i}$

= $\frac{3.2 \times 0.82 sec}{18.2} - 1.85$

= -1.705 m/s

Hence, we can conclude that the final velocity of the mass if it is initially moving along the x-axis with a velocity of 1.85 m/s to the left is 1.705 m/s towards the left.
