Good question. The Arizona impact location is very, very, unique. The crater was the Bigger than Cuba when it first struck. Due to sedimentary drop off its size is slowly decaying. It is currently about the size of 2-3 Carnival cruise ships.

Answer:

The meteor crater in Arizona is still visible  due to the sedimentary nature of the materials present, mainly limestone, and the total absence of lava in the zone.

Most of the craters created by other meteorites that have collided with the earth are not visible at present because they were smaller and also impacted in areas where the soil materials were more compact and firm.

Explanation:

It is estimated that the impact produced by the crater 50,000 years ago, and was caused by an nickel-iron meteorite about 50 m long traveling at an approximate speed of 12 km/sec.  The impact created a temperature so extraordinarily high that it vaporized or melted all the rocks in the surrounding crust.

A town requiring 2.0 m3/s of drinking water has two sources, a local well with 15 g/m3 nitrate (as N) and a distant reservoir wi
kati45 [8]

Explanation:

Drinking water requirement in town 2.0 m^3/s of water per second

nitrate in local well  nitrate per 15 \mathrm{m}^{3} of water

nitrate in distant reservoir =5 \mathrm{~g} / \mathrm{m}^{3}

Let the flow rate of well

flow rate of reservoir =y m^{3} / s

Drinking water requirement is 45 \mathrm{ppm} or 45 \mathrm{~g} / \mathrm{m}^{3}

therefore, the total flow of drinking water

Two charged objects separated by some distance attract each other. If the charges on both objects are doubled with no change in
beks73 [17]

Answer:

a. the force between them quadruples

Explanation:

The electrostatic force between two charges is given by

F=k\frac{q_1 q_2}{r^2}

where

k is the Coulomb's constant

q1 and q2 are the two charges

r is the separation between the two charges

In this problem, the charges on both objects are doubled, so

q_1' = 2q_1\\q_2' = 2q_2

While the distance does not change, so the new force will be

F'= k \frac{(2q_1)(2q_2)}{r^2}=4 (k\frac{q_1 q_2}{r^2})=4 F

so, the force will quadruple.
