The two main factors that affect density of ocean water are the temperature of the water and the salinity of the water.
While a majority of Jewish migrants have come from Europe, more than three-quarters of those alive today have moved to the Middle East-North Africa region, almost entirely to Israel.
The air around you has weight, and it presses against everything it touches. That pressure is called atmospheric pressure, or air pressure. It is the force exerted on a surface by the air above it as gravity pulls it to Earth. Atmospheric pressure is commonly measured with a barometer.
<h2>
Answer: It is the same force that causes an apple to fall to the ground.</h2>
The force that makes two galaxies to be attracted to each other is the same force that causes an apple to fall to the ground. This is known as the Gravity Force.
This force was named by Issac Newton, after some empirical observations in nature and then he published the Universal Law of Gravitation on 1687:
<em>The force exerted between two bodies of masses and and separated by a distance is equal to the product of their masses and inversely proportional to the square of the distance.</em>
Written in a mathematical form is:
Where is the gravitational constant
So, this force between two bodies (two galaxies or an apple and the ground) is directly proportional to the product of the mass of both and inversely proportional to the square of the distance that separates both bodies.
This means the gravity force <u>decreases</u> when the distance between these two bodies <u>increases</u>.
Therefore, the correct option is a.
Answer:
Explanation:
An air mass forms whenever the atmosphere remains in contact with a large, relatively uniform land or sea surface for a time sufficiently long to acquire the temperature and moisture properties of that surface. The Earth's major air masses originate in polar or subtropical latitudes.
