What occurs when a rock is crushed into a pile of fragments?

1 answer:

3 0

The answer to the question is the total surface area increases and chemical composition changes. Consider the breakdown of rock into smaller pieces, these fragments vary from huge rocks to smaller sizes. As they are so crushed and broken they tend to occupy much of the surface area than when its just a huge rock.

Sergio [31]

Answer:

Explanation:

Building and business closures for weeks or months reduce water usage, potentially leading to stagnant

water inside building plumbing. This water can become unsafe to drink or otherwise use for domestic or

commercial purposes. For example, optimal growth conditions for undesirable pathogens, such as

Legionella bacteria, can occur when hot water temperatures decrease and disinfectant residuals (e.g.,

chlorine) drop to low levels. Water chemistry changes may also increase corrosion and leaching of

metals, including lead, and may cause the formation of disinfection by-products. Turning on the water

for immediate use after it has been stagnant can pose a risk to public health if not properly managed.

Additionally, turning on water after a prolonged period of non-use could disrupt pipe and plumbing

scales to such an extent that microbial and chemical contaminants could be released into the water.

On a coordinate plane, a line goes through (negative 3, negative 3) and (negative 1, 5). What is the equation of the line parall

DENIUS [597]

Answer:

y=4x-16

Explanation:

The general form of the equation of a line is: y=mx+x, where m is the gradient and c is the y-intercept.

Given points (-3,-3) and (-1,5)

We are to find the equation of the line parallel to the given line with an x-intercept of 4.

First, we determine the value of the gradient of the line.

Gradient,

$m=\frac{y_2-y_1}{x_2-x_1} \\=\frac{5-(-3)}{-1-(-3)} \\=\frac{5+3}{-1+3}\\=\frac{8}{2}\\m=4$

Two lines are parallel if their gradients $m_1 \: and \: m_2$ are equal.

The gradient of the line parallel to the given line $m_2=4$

Since the x-intercept of the new line is 4, a point on the new line, $(x_1,y_1)=(4,0)$

Substituting $(x_1,y_1)=(4,0)$ into the equation of a line: , $y-y_1=m(x-x_1),$ we have:

$y-0=4(x-4)\\$Therefore:\\y=4x-16$

Therefore, the equation of the line is: y=4x-16
