Which of these factors best explains why liquid water exists on earth ?

Physics
2 answers:
Crazy boy [7]2 years ago
5 0

Answer: The "right" answer would be something like

"The temperature of the earth is such that permits the existence of liquid water"

Now let's analyze the option that can mean this:

The b option "Earth strong gravity" is related to the mass of the earth, and the mass of the earth is, in some way, what defines the orbit that Earth has around the sun.

So if the orbit of earth was closer to the sun, the liquid water would boil, and if the orbit was further away from the sun, the liquid water would freeze.

Then the option b is the one that best explains why liquid water exists on earth.

Answer:

earth strong gravity

Explanation:

The only planet that have water bodies is earth. We know that water is one of the important factors for all living organism. Liquid water exists on the earth's surface is due to the atmospheric pressure. The reason behind this is not completely mentioned.

There are so many hypothesis about it. Out of given options the correct option is earth's strong gravity.

Hence, the correct option is (b) " earth strong gravity ".

A bullet is fired into the air at an angle of 45°. How far does it travel before it is 1,000 feet above the ground? (Assume that
Readme [11.4K]

Answer:

It travels 1414 feets.

Explanation:

Let's take the length the bullet travels <em>l </em>as the hypotenuse of a right triangle and the height it reaches one of its sides. Since we got the angle α at which it was fired and the height <em>h</em> it reached, we can calculate <em>l</em> using the <em>sin(α)</em> function:

sin(\alpha )=\frac{opposite side}{hypotenuse}\\sin(\alpha)=\frac{h}{l}\\l=\frac{h}{sin(\alpha)}

Replacing:

l=\frac{1000ft}{sin(\frac{\pi}{4})}

Solving and roundin to the nearest foot:

l=1414 ft
