Answer: 1,001 Nights, also known as Thousand and one Nights or Arabian Nights.
Explanation:
Answer:
(a) Lower densities and higher thermal gradient
Explanation:
Over pressured zones during penetrating are those zones where development liquid weight (higher than expected) surpasses the mud weight. These are liable for victories.
- The pore liquid substance in shales of the over constrained zone is higher than the ordinary compelled shales. That implies, the porosity of shales in over pressured zone is higher as well thus the thickness of the over forced zones are lower than the ordinary influenced shales.
- Because of the nearness of more liquids in the pores of an over constrained shale, the warmth produced because of penetrating behaviors gradually in over influenced shale than a shale in typical weight zones. Accordingly, warm inclination will be higher in over forced shales.
A radioactive element with a half-life of 1,000 years, and starting mass of 20 grams, will need 2,000 years to decrease to 5 grams.
Explanation:
The radioactive elements all have a specific half-life. Each element's half-life is well known, and they are used by scientists of numerous fields as they are excellent for determining the age of a particular item, be it or organic or non-organic nature. In this case, we have a radioactive element with a half-life of 1,000 years, and starting mass of 20 grams.
The half-life basically means that half of the mass of an element is lost during a particular period of time. For the element in question we need to find out how much time will be needed for it to decrease to 5 grams. In order to get to the result, we just need to add 1,000 years on every decrease of half of the mass:
20/2 = 10
10/2 = 5
So in 1,000 years, the element in question will decrease to 10 grams, and in further 1,000 years (2,000 cumulatively) it will decrease to 5 grams.

Answer: The greater the distance to a galaxy, the greater its redshift</h2>
When we talk about the <u>visible electromagnetic spectrum</u>, we know it starts in violet-blue and ends in red.
Now, in this context the astronomer Edwin Powell Hubble observed several celestial bodies, and when obtaining the spectra of distant galaxies he observed the spectral lines were displaced towards the <u>red</u><u> </u>(red shift), whereas the nearby stars showed a spectrum displaced to the <u>blue</u>.
From there, Hubble deduced that the farther the galaxy is, the more redshifted it is in its spectrum, and noted that all galaxies are <em>"moving away from each other with a speed that increases with distance"</em>, and enunciated the now called<u> Hubble–Lemaître Law</u>.
This means in the past the distance between two galaxies was smaller than at present, being this the proof that <u>the universe is expanding</u> (like a balloon expands when it is filled with air or another gas).
At this poitn it is important to stay clear that <u>the redshift is not produced by the relative movement of the galaxies with each other</u>. This effect is in fact, due to the <u>own expansion of the space</u> among the galaxies.
