PLS HELP GIVE ONE PARAGRPAPH

The electromagnetic spectrum is the range of frequencies (the spectrum) of electromagnetic radiation and their respective wavelengths and photon energies. The electromagnetic spectrum covers electromagnetic waves with frequencies ranging from below one hertz to above 10²⁵ hertz, corresponding to wavelengths from thousands of kilometers down to a fraction of the size of an atomic nucleus.
How the light affect the color we see?
All of the colors we see are a byproduct of spectrum light, as it is reflected off or absorbed into an object. An object that reflects back all of the rays of light will appear white; an object that absorbs all of the rays, black. All of the millions of other colors are produced by a combination of light rays being absorbed and reflected.

Answer:
The waves have energy that wave back and forth because the waves are never still, they are always moving. There are different types of waves because sometimes (like a tsunami) the waves are affected by other things like the earth plates.

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!

They do the following experiment: (second image)
The students finish conducting their tests and conclude that using a taller ramp and a larger ball will make the ball roll further. Is their conclusion based on a reliable experiment?
A.Yes, because they used the same color balls.

Calculate the change in the kinetic energy (KE) of the bottle when the mass is increased. Use the formula
KE = one half.mv2, where m is the mass and v is the speed (velocity). Assume that the speed of the soda bottle falling from a height of
0.8 m will be 4 m/s, and use this speed for each calculation.
Record your calculations in Table A of your Student Guide.
When the mass of the bottle is 0.125 kg, the KE is
kg m2/s2.
When the mass of the bottle is 0.250 kg, the KE is
kg m2/s2.
When the mass of the bottle is 0.375 kg, the KE is
kg m2/s2.
When the mass of the bottle is 0.500 kg, the KE is
kg m2/s2.

1. The kinetic energy of the bottle is 1 Kg.m²/s²
2. The kinetic energy of the bottle is 2 Kg.m²/s²
3. The kinetic energy of the bottle is 3 Kg.m²/s²
4. The kinetic energy of the bottle is 40 Kg.m²/s²
How do I determine the kinetic energy?The kinetic energy can be obtain as illustrated below:
1. For mass 0.125 Kg
Mass (m) = 0.125 KgVelocity (v) = 4 m/sKinetic energy (KE) =?KE = ½mv²
KE = ½ × 0.125 × 4²
Kinetic energy = 1 Kg.m²/s²
2. For mass 0.250 Kg
Mass (m) = 0.250 KgVelocity (v) = 4 m/sKinetic energy (KE) =?KE = ½mv²
KE = ½ × 0.250 × 4²
Kinetic energy = 2 Kg.m²/s²
3. For mass 0.375 Kg
Mass (m) = 0.375 KgVelocity (v) = 4 m/sKinetic energy (KE) =?KE = ½mv²
KE = ½ × 0.375 × 4²
Kinetic energy = 3 Kg.m²/s²
4. For mass 0.500 Kg
Mass (m) = 0.500 KgVelocity (v) = 4 m/sKinetic energy (KE) =?KE = ½mv²
KE = ½ × 0.500 × 4²
Kinetic energy = 40 Kg.m²/s²

The change in kinetic energies are 1 \(kg m^{2}/s^{2}\), 2 \(kg m^{2}/s^{2}\), 3 \(kg m^{2}/s^{2}\), and 4 \(kg m^{2}/s^{2}\) respectively as the mass of the bottle is changed as 0.125kg, 0.250kg, 0.375kg, and 0.500kg.
Given the velocity v=4m/s.
KE=\(1/2 mv^{2}\)
Here KE represents the Kinetic energy of the bottle, m represents the mass of the bottle which is varying time to time, and v represents the velocity of the bottle which is constant over time.
For the first case:
Given mass m=0.125kg
∴KE=\(1/2mv^{2}\)
=1/2*(0.125)*(4)²
=1 \(kg m^{2}/s^{2}\)
Hence the change in kinetic energy of the bottle when it became 0.125kg is 1 kg m²/s².
For the second case:
Given mass m=0.250kg
∴KE=\(1/2mv^{2}\)
=1/2*(0.250)*(4)²
=2 \(kg m^{2}/s^{2}\)
Hence the change in kinetic energy of the bottle when it became 0.250kg is 2 kg m²/s².
For the third case:
Given mass m=0.375kg
∴KE=\(1/2mv^{2}\)
=1/2*(0.375)*(4)²
=3 \(kg m^{2}/s^{2}\)
Hence the change in kinetic energy of the bottle when it became 0.375kg is 3 kg m²/s².
For the final case:
Given mass m=0.500kg
∴KE=\(1/2mv^{2}\)
=1/2*(0.500)*(4)²
=4 \(kg m^{2}/s^{2}\)
Hence the change in kinetic energy of the bottle when it became 0.500kg is 4 kg m²/s².
