Correct Answer:
B.They may cause small craters on Earth’s surface.
Explanation:
<u><em>Asteroids and comets are solid particle of mass (Asteroids are rocky; comets are dirty snowballs.) that floats and revolves around the outer space. </em></u>When this mass is pulled towards the earth, it tends to fall right into the earth surface. And, also, the asteroids tends to fall into the earth once few times in a centuries.
The effect of the asteroids hitting the earth would lead to the creation of craters on the Earth's surface (A huge whole like a dent on the earth surface). <em> An Example is the one hat happened in 1908 -- An asteroid estimated at 50 meters across explodes above Tunguska, Siberia, blowing down trees across 2,000 square kilometre and killing a thousand reindeer, but apparently no people. </em>
Answer:
A- 2/7 of the initial weight.
B- 28.58% of the initial weight.
Explanation:
A- To determine the weight fraction that the dog must lose to be healthy, we have to take into account the common divisor between 35 and 25. Both are divisible by 5, so we must calculate based on that number to obtain a comparable fraction between both weights.
So, the dog must go from weighing 35/35 to weighing 25/35, that is, from weighing 7/7 to weighing 5/7. Therefore, the dog should lose 2/7 of its weight to reach the ideal weight.
B- To determine the percentage of weight that the dog must lose to reach its ideal weight, it is determined through a cross multiplication:
35 kg = 100%
25 kg = X
(25 x 100) / 35 = X
2500/35 = X
71.42 = X
So, the 25 kg represents 71.42% of the initial 35 kg. Therefore, the 10 kg lost represent 28.58% of the initial weight (100 - 71.42).

<span>Individuals suffering from clinical depression are more likely to suffer heart disease and heart attacks. One primary factor is that individuals who are depressed are less likely to engage in good self care strategies: they are more likely to drink and smoke, they are less likely to exercise, and they are less likely to take prescribed medications. Physically, the stress that is associated with depression may lead to plaque formation in the arteries.</span>
Answer:
Symbolic representation of the hydrogen atom: nucleus (in red) and electron (in black the atomic orbital of the electron). The molecule would consist of two hydrogen atoms.
The hydrogen atom is the simplest atom that exists and the only one that admits an exact analytical solution from the point of view of quantum mechanics. The hydrogen atom is also known as a monoelectronic atom, because it is formed by a proton that is in the nucleus of the atom and contains more than 99.945% of the mass of the atom, and a single electron - about 1836 times less massive than the proton- "orbit" around said nucleus (although there may also be hydrogen atoms with nuclei formed by a proton and 1 or 2 more neutrons, called deuterium and tritium, respectively).
A pedagogical analogy of the hydrogen atom can be made with a Solar System, where the sun would be the only atomic nucleus and that has the largest amount of mass - specifically 99.86% of the Solar System - and in its planet orbit (Electron ) that would make up the rest of the mass of the System (protium atom (1H)). This makes hydrogen the simplest of all the elements in the periodic table of the elements.
