Answer:
12
Explanation:
A solar eclipse occurs when the moon in between the sun and the earth. Since in reality, the moons orbit is inclined, this aligning doesnt occur often. But if the orbit of the moon were in the same plane as the earth orbit, and since the moon orbits the earth once a month, the three objects would align every month. This makes it 12 times in a year.
-The group 7 elements are also known as the halogens.
They include fluorine, chlorine, bromine and iodine, which all have seven
electrons in their outer shell.
-The noble gases
make a group of chemical elements with comparable properties; under standard
conditions, they are all odorless, colorless, monatomic gases with very low
chemical reactivity. The six noble gases that occur naturally are helium, neon,
argon, krypton, xenon, and the radioactive radon. FACT: They can also act like
a glow stick.<span>[ID1] </span>

False. Velocity is a vector and is measured in m/s (in SI, anyway).
Explanation:
Before mitosis, the chromosomes are copied. They then coil up, and each chromosome looks like a letter X in the nucleus of the cell. The chromosomes now consist of two sister chromatids. Mitosis separates these chromatids, so that each new cell has a copy of every chromosome
The answer is:
D: The distance between the objects squared.
The gravitational force between two objects is proportional to their masses and inversely proportional to the square of the distance between their centers. Result: 'g' is independent of mass of object !! Hope this helped :)
