What step of the rock cycle happens as the sea stacks are broken down

lesya692 [45]

D. Weathering

The six steps of the rock cycle includes Weathering and Erosion, Transportation, Deposition, Compaction and Cementation. Metamorphism, Rock Melting.

Deposition is the process where rock particles sink at the rivers and become sediment.

Weathering is the process by which wind and water breaks down igneous, sedimentary, and metamorphic rocks. The process refers to large rocks broken down into smaller pieces and the broken off particles stay in the area.

You're in a car that gets 37 miles per gallon of gas, driving it at a constant speed. If you took the gas from the car tank, and

Answer:

Required diameter of hose pipe = 0.2864 mm

Solution:

From the continuity eqn, the fluid flow rate is given by:

Av = $\frac{V}{t}$

where

A = cross-sectional area = $\pi r^{2}$

r = hose pipe radius

v = velocity of gas

Also, $v = \frac{displacement, d}{time, t}$

Using:

1 gallon = 3.854 l

1 mile = 1609.34 m

$1 m^{3} = 1000 l$

Therefore,

$A\frac{d}{t} = \frac{V}{t}$

$\pi r^{2} = \frac{V}{d}$

$\pi r^{2} = \frac{(1 gal).(\frac{3.7854 l}{gal}).(\frac{10^{- 3} m^{3}}{l})}{37 miles(\frac{1609.34 m}{miles})}$

$6.357\times 10^{- 8} = \pi r^{2}$

$r^{2} = 2.024\times 10^{- 8}$

$r = 1.423\times 10^{- 4} m = 0.1423 mm$

The diameter of the hose pipe = 2r = $2\times 1.423\times 10^{- 4}$

The diameter of the hose pipe = $2.846\times 10^{- 4} m = 0.2846 mm$
