Explanation:
Electrons play a major role in all chemical bonds. There is one type of bonding called electrovalent bonding (ionic), where an electron from one atom is transferred to another atom. You wind up creating two ions as one atom loses an electron and one gains one.

List three evidences that show that the Bible is the Word of God.
Answers
Answer:1.God tells us that He is the Author (2 Peter 1:20-21 Open in Logos Bible Software (if available) & 2 Timothy 3:15-17 Open in Logos Bible Software (if available))
1.The Old Testament and New Testament Authors understood they were writing the Word of God. Common Old Testament phrase – “Thus saith the Lord”. The Apostle Peter confirmed the Apostle Paul’s writings as Scripture (2 Peter 3:16)
3.Its Historical Accuracy – as verified by archeology, which has never contradicted the Bible, but only confirms and silences its critics.
Explanation:
Answer:
Many people question who the author of the Bible is and wonder if the Bible is really the Word of God. I want to give you five reasons to affirm that the Bible is God's Word.
The Word of God: Evidence that Scripture is Divine
First, I believe the Bible is the Word of God because of its scientific accuracy. The Truth of the Word of God tells us that God “hangeth the earth upon nothing” (Job 26:7). How did Job know that the earth hung in space before the age of modern astronomy and space travel? The Holy Spirit told him. The scientists of Isaiah’s day didn’t know the topography of the earth, but Isaiah said, “It is [God] that sitteth upon the circle of the earth” (Isaiah 40:22). The word for “circle” here means a globe or sphere. How did Isaiah know that God says upon the circle of the earth? By divine inspiration.
Secondly, the Bible is affirmed through historical accuracy. Do you remember the story about the handwriting on the wall that is found in the fifth chapter of Daniel? Belshazzar hosted a feast with a thousand of his lords and ladies. Suddenly, a gruesome hand appeared out of nowhere and began to write on a wall. The king was disturbed and asked for someone to interpret the writing. Daniel was found and gave the interpretation. After the interpretation, “Then commanded Belshazzar, and they clothed Daniel with scarlet, and put a chain of gold about his neck, and made a proclamation concerning him, that he should be the third ruler in the kingdom.” (Daniel 5:29). Basing their opinion on Babylonian records, the historians claim this never happened. According to the records, the last king of Babylon was not Belshazzar, but a man named Nabonidas. And so, they said, the Bible is in error. There wasn’t a record of a king named Belshazzar. Well, the spades of archeologists continued to do their work. In 1853, an inscription was found on a cornerstone of a temple built by Nabonidas, to the god Ur, which read: “May I, Nabonidas, king of Babylon, not sin against thee. And may reverence for thee dwell in the heart of Belshazzar, my first-born favorite son.” From other inscriptions, it was learned that Belshazzar and Nabonidas were co-regents. Nabonidas traveled while Belshazzar stayed home to run the kingdom. Now that we know that Belshazzar and Nabonidas were co-regents, it makes sense that Belshazzar would say that Daniel would be the third ruler. What a marvelous nugget of truth tucked away in the Word of God!

this is for science class Gravity and Mass vs. Weight Notes
Answers
Answer:
Explanation:
There are two factors that affect gravity: mass and distance.
Law of Gravity: Every particle attracts every other particle in the universe with a force that is directly proportional to the product of their masses and inversely proportional to the square of the distance between their centers.
Gravity: the force by which each object draws all the other objects towards its center.
Gravity is affected by mass and distance.
Everything with mass has gravity.
The more mass an object has, the more gravity it has.
The farther you are from the source of gravity, the lesser of gravity you will feel.
In space, your weight will read 0 and the objects in space are hard to move due to the different gravitational forces acting upon each object from different areas.
Weight: Weight is the force of gravity on an object.
Weight is completely dependent on gravitational force acting on an object.
The more gravity there is, the more weight an object will have.
Mass and weight are not the same.
Mass does not change because it is the amount of matter in an object which does not change no matter where the object is. However, weight changes because it is the effect of gravity on an object.
In order to find weight, use the formula W=mg where W is the weight, m is the mass and g is the gravitational force.

Answers
Answer:

The effect of radiation on different surfaces will eventually result in the destruction of the habitats and will affect the organisms living at these regions.
What is meant by radiation ?Radiations are defined as the type of electromagnetic waves or sub-atomic which are emitted as high energy carrying particles.
Here,
The radiations that fall on the different surfaces will affect the climatic conditions over that regions. It varies from the tropical regions to temperate regions.
The earth's average temperature is due to the solar radiations reaching from the sun towards the earth surface.
The surface of earth is regularly cooled due to the presence of the artic and other regions that absorbs less heat and mostly are released back into the space effectively.
The rate of reflection of sunlight by the surface is called Albedo.
But the increased emission of the radiations causes the surface temperature of the earth to a greater extent. This will result in the melting of ice in the colder regions like ice-covered lakes, at a higher rate. Thus the rate of absorption of radiation will be increased in these surfaces.
Also, in the forest and oceans or an asphalt road, the effect of increased radiation reaching these surfaces will lead to a decrease in the albedo effect.
Hence,
The effect of radiation on different surfaces will eventually result in the destruction of the habitats and will affect the organisms living at these regions.

In a collision between two objects, both objects experience forces that are equal in magnitude and opposite in direction. Such forces often cause one object to speed up (gain momentum) and the other object to slow down (lose momentum). According to Newton's third law, the forces on the two objects are equal in magnitude.

On a distance-versus-time graph, _____.

B.) if the line has a constant slope, the speed may be changing
C.) slope is calculated by dividing the run by the rise
D.)if the slope is zero, the object is moving slowly
Answers
Answer:
A
Explanation:
The slope of the graph has the units of vertical axis divided by horizontal axis. This means that the slope of a distance vs time graph is distance/time, or velocity.
Slope is calculated by "rise over run" so C is incorrect.
Since the slope represents velocity, a constant slope equates to a constant velocity, hence B is incorrect. Same reasoning for D being incorrect: if the slope is zero, the object is not moving.

If Neptune’s mass were reduced, what could be done to maintain the same force of gravitational attraction between Neptune and the Sun?
Answers
Answer:
Neptune and the Sun would need to move farther apart.
Explanation:
The equation for gravitational force is F = Gm1m2/d2 where G is the gravitational constant, m1 and m2 are the masses of the bodies in question, and d is the distance between the two.
Since the masses are proportional to the distance, if the mass of one body is reduced, the distance between them must also be reduced in order to keep the same gravitational force between them.
