Answer:
The lack of sufficient water resources, including a lack of access t safe water supplies, to meet water needs within a region.
Explanation:
Answer:
The asteroid requires 5.14 years to make one revolution around the Sun.
Explanation:
Kepler's third law establishes that the square of the period of a planet will be proportional to the cube of the semi-major axis of its orbit:
(1)
Where T is the period of revolution and a is the semi-major axis.
In the other hand, the distance between the Earth and the Sun has a value of
. That value can be known as well as an astronomical unit (1AU).
But 1 year is equivalent to 1 AU according with Kepler's third law, since 1 year is the orbital period of the Earth.
For the special case of the asteroid the distance will be:


That distance will be expressed in terms of astronomical units:
⇒ 
Finally, from equation 1 the period T can be isolated:

Then, the period can be expressed in years:


Hence, the asteroid requires 5.14 years to make one revolution around the Sun.
<u><em>The right answer is "A) Substance is denser as a solid than as a gas" Trust me I just got it wrong because of this guy down here or girls not trying to judge</em></u>
Answer:
The difference is that water is an incompressible fluid — its density is almost constant as the pressure changes — while air is a compressible fluid — its density changes with pressure. ... Atmospheric pressure is the pressure exerted on a surface by the weight of the atmosphere (a compressible fluid) above it
