Explanation:

Wastewater can contain physical, chemical and biological pollutants. Households may produce wastewater from flush toilets, sinks, dishwashers, washing machines, bath tubs, and showers. ... After treatment at a wastewater treatment plant, treated wastewater (also called effluent) is discharged to a receiving water body.

Wastewater is "used water from any combination of domestic, industrial, commercial or agricultural activities, surface runoff or stormwater, and any sewer inflow or sewer infiltration". Therefore, wastewater is a byproduct of domestic, industrial, commercial or agricultural activities.

ziro4ka [17]

Answer:

The baseball would seem to be traveling with a velocity 0.98918c of 98.92% of the speed of light as seen from the Earth.

Explanation:

This problem involves the relativistic effects. The pitcher throws the ball with a velocity u' which is 65% of the speed of light c i.e. u' = 0.65c

The velocity V of the spaceship in which he is practicing is 95% of the speed of light. Therefore V = 0.95c

So if the ball is thrown in the same direction as the direction of the spacecraft's motion, then classically, the velocities would add up and exceed the speed of light. But we know that this is not possible. It is prohibited by the special theory of relativity. So we need to consider the relativistic addition of velocities to calculate the velocity (u) of the ball as seen from the Earth.

The formula for relativistic addition of velocities is expressed below,

$u=\frac{V+u'}{1+\frac{Vu'}{c^2}}$

We know that u' = 0.65c and V = 0.95c. now we can calculate u which is the velocity of the baseball as seen from Earth as follows

$u=\frac{0.95c+0.65c}{1+\frac{0.95c\times 0.65c}{c^2}}$

$u=\frac{1.6c}{1+\frac{0.6175c^2}{c^2}}$

$u = \frac{1.6c}{1.6175}$

u = 0.98918c

So the baseball would seem to be traveling with a velocity 0.98918c of 98.92% of the speed of light as seen from the Earth.

Answer:

The Answer is: C.) It shows that as human needs and resources change, societies develop differently.

Explanation:

The chart depicted shows three different types of societies and their needs. Each society has a different need: Agricultural societies have a need for water and fertile land, Industrializing societies have a need for resources and technology, and Modern societies have a need for technology and cities. I hope this was helpful and please rate accordingly so others can see if it was.
