What scientists use to make models of the Earth's water cycle so they can<span> see how it is ...

Precipitation is a vital component of how water moves through Earth’s water cycle, connecting
the ocean, land and atmosphere. Water evaporates from the surface of the land and oceans,
rises and cools, condenses into rain or snow, and falls again to the surface as precipitation. The
water falling on land collects in rivers and lakes, soil, and porous layers of rock, and much of it
flows back into the oceans. The cycling of water in and out of the atmosphere is a significant
aspect of the weather patterns on Earth. so that will be probs the best i can do
Answer:
<em>The second drop is 3.75 m above the ground</em>
Explanation:
<u>Free Fall Motion</u>
A free-falling object falls under the sole influence of gravity without air resistance.
If an object is dropped from rest in a free-falling motion, it falls with a constant acceleration called the acceleration of gravity, which value is .
The distance traveled by a dropped object is:
If we know the height h from which the object was dropped, we can find the time it takes fo hit the ground:
When the first drop touches the ground there are two more drops in the air: the second drop still traveling, and the third drop just released from the tap.
The total time taken for the first drop to reach the ground is:
Half of this time has taken the second drop to fall:
It has fallen a distance of:
Thus its height is:
h = 5 - 1.25 = 3.75
The second drop is 3.75 m above the ground
Answer: bismuth and nitrogen, because they have the same number of valence electrons
Explanation:
Elements are distributed in groups and periods in a periodic table.
Elements that belong to same groups will show similar chemical properties because they have same number of valence electrons.
The number of valence electrons in Bismuth and nitrogen are 5 and thus thus they will show similar chemical properties and thus belong to the same group.
The atomic masses of elements in a group will differ drastically.
The group number has got nothing to be the isolation year.
Thus bismuth and nitrogen belong to same group because they have the same number of valence electrons
The kilogram is the Standard International System of Units unit of mass. It is defined as the mass of a particular international prototype made of platinum-iridium and kept at the International Bureau of Weights and Measures.
