Match each item with the clean water regulation it describes. (2 points)

Leona [35]

The correct match of each item to the clean water regulation it describes is as follows:

Regulates pollutants discharged into surface waters: Clean water act
Covers both surface and ground waters: Safe drinking water act
Authorizes the EPA to establish minimum standards for tap water: Safe drinking water act
Funds sewage treatment plants: Clean water act

<h3>What are the functions of clean water regulation?</h3>

Clean Water Act (CWA) is a regulatory body that establishes the basic structure for the regulation of pollutants discharge and maintenance of quality standards of the surface waters.

On the other hand, the Safe Drinking Water Act was founded to oversee the protection of the quality drinking water. The regulatory body is primarily concerned with potable water all waters, whether from above ground or underground sources.

Therefore, the correct match of each item to the clean water regulation it describes is as follows:

Regulates pollutants discharged into surface waters: Clean water act
Covers both surface and ground waters: Safe drinking water act
Authorizes the EPA to establish minimum standards for tap water: Safe drinking water act
Funds sewage treatment plants: Clean water act

One of the main factors driving improvements in the cost and complexity of integrated circuits (ICs) is improvements in photolit

nika2105 [10]

Answer:

0.000003782 m

0.000001891 m

0.000001197125 m

Explanation:

$\lambda$ = Wavelength = 248 nm

D = Diameter of beam = 1 cm

f = Focal length = 0.625 cm

The angle is given by

$\theta=\dfrac{1.22\lambda}{D}$

The width is given by

$d=2\theta f\\\Rightarrow d=2\dfrac{1.22\lambda f}{D}\\\Rightarrow d=2\dfrac{1.22\times 248\times 10^{-9}\times 6.25\times 10^{-2}}{1\times 10^{-2}}\\\Rightarrow d=0.000003782\ m$

The required width is 0.000003782 m

Minimum resolvable line separation is given by

$\dfrac{0.000003782}{2}=0.000001891\ m$

The minimum resolvable line separation between adjacent lines is 0.000001891 m

when $\lambda=157\ nm$

$d=2\dfrac{1.22\times 157\times 10^{-9}\times 6.25\times 10^{-2}}{1\times 10^{-2}}\\\Rightarrow d=0.00000239425\ m$

The new minimum resolvable line separation between adjacent lines is

$\dfrac{0.00000239425}{2}=0.000001197125\ m$

A SUV is towing a trailer and accelerating on a level road. The force that the SUV exerts on the trailer is _____. equal to the

stepladder [879]

Answer:

equal to the force the trailer exerts on the road.

Explanation:

Because of the tension of the rope, the force that the SUV exerts on the trailer is equal and opposite to the force that the trailer exerts on the SUV. This is explained in Newton's third law of motion, which states that for every action, there is always an equal and opposite reaction.
