<span>The most common method in removing debris and living organisms is through a series of sedimentation and heat application. The role of sedimentation is to use gravity in separating drinkable water and visible debris. While treating water with heat kills the living organisms.</span>

<u>Step-1: Coagulation</u>

Coagulation removes fine particles suspended in water, after removing rough debris by filtering through the screen.
Alum and other chemicals are added to water to form small sticky particles called floc, which attracts suspended particles.
The combined weight of these particles and alum (floc) becomes heavy enough to sink.

<u>Step-2: Sedimentation</u>

Coagulated particles fall gravitationally through the water in a settling tank and accumulate at the bottom of the tank, cleaning water from much solid debris.

<u>Step-3: Filtration</u>

To remove solid particles that were previously unremoved by sedimentation, water from the sedimentation tank flows through:

sand,
gravel,
coal, and
activated charcoal.

<u>Step-4: Disinfection</u>

Disinfection methods are applied to filtered water to destroy hazardous microorganisms as living organisms.

A chlorine residue is added to water when leaving the processing plant to help protect treated water from recontamination when moving through the distribution system.

<h3>Further explanation</h3>

Chemical precipitation or coagulation with various aluminum salts (e.g., alum), iron, lime, and other organic or inorganic chemicals is widely used to treat water to remove colloidal particles (turbidness) and microbes.

Water treatment with the addition of coagulants and chemical deposits has been carried out since ancient times.

There are main things to know about the different terms of water purification and filtration because they are not synonyms.

Water filtration is a treatment for eliminating debris, and some bacteria as living organisms, through several types of filters like cloth or nets.
Water purification is a chemical or UV process (with heat treatment) to deactivate bacteria and other hazardous substances that are not functioning.

In position time graphs, otherwise known as distance time graphs, acceleration/decceleration occurs when the line curves, which looks like the picture I've included.

In hours 2 to 3, the object does not accelerate, but instead stays at a constant speed of 20m per hour.

Which object has the greatest

Lyrx [107]

Answer:

H-a seated high school student

Explanation:

"Inertia" is an important word in Physics. It is the resistance of an object to any change in motion. Measuring the amount of inertia largely relies on the "mass of an object." The heavier the object, the more likely it is able to resist any change in motion.

Among the choices above, the high school student is the heaviest and has greater mass than the leaf, softball or balloon. This means, <u>it has the greatest inertia.</u>

Thus, this explains the answer.

When you throw a ball, the work you do to accelerate it equals the kinetic energy the ball gains. If you do twice as much work w

aniked [119]

Answer:

No. Twice as much work will give the ball twice as much kinetic energy. But since KE is proportional to the speed squared, the speed will be $sqrt{2}$ times larger.
