You lose energy when you collide with the surface in sound and heat.
It is also that when you jump on the floor, in order to keep you from going through the floor, the floor needs to put a force that will say 'Hey you can't go through me' that's why we build houses and supports with extra strength to hold us, and all the forces we exert on them.

When you drop something, first of all it accelerates.
The faster it falls, the bigger the force of ______ that acts on it.
choose from the list to complete the sentence:
friction gravity air pressure
note: apparently the answer is friction but it doesn't make sense to me so please explain.
The faster an object is going, the more resistance there will be. An example of this would be if you're running the faster you run, the more air is going against you.

list both types of energy before skydiver jumps out of the plane and as the sky diver is diving.
Answer : This is an example of Kenitic and potential energy
Explanation:
kenitic: the act of moving or motion
potential: not. moving YET
he was not moving when he was on the plane and had potential energy cause he wasn't getting pulled down and kenitic energy was when he was getting pulled down from force of gravity when he was getting pulled to the ground when he was skydiving

How do factors such as ocean currents, water temperature, and weather affect you in your daily life?
Answer:One way that the world’s ocean affects weather and climate is by playing an important role in keeping our planet warm.
Explanation:The majority of radiation from the Sun is absorbed by the ocean, particularly in tropical waters around the equator, where the ocean acts like a massive, heat-retaining solar panel. Land areas also absorb some sunlight, and the atmosphere helps to retain heat that would otherwise quickly radiate into space after sunset.

Mahiya and Mrinmoy are in a relay around a square field with each side of length 60m. First, Mahiya runs at a speed of 6 ms−1 for 60m to pass a baton to Mrinmoy. Then Mrinmoy runs 120m at 4ms−1 while Mahiya runs through the field to reach the other corner. Then Mrinmoy passes the baton. But Mahiya is now tired since she has been constantly running. So, she only runs at 3ms−1 for the final 60m. What is the average speed of the baton in ms−1?
The average speed of the baton can be determined by dividing the total distance travelled by the total time taken for that travelling.
\(Average\ Time = \frac{Total\ Distance}{Total\ Time}\)
First, we will find the total distance, by adding the distances travelled by both Mahiya and Mrinmoy, while carrying the baton.
\(Total\ Distance = Distance\ Travelled\ by\ Mahiya\ to\ pass\ the\ baton\ to\ Mrinmoy\ +\ Distance\ Travelled\ by\ Mrinmoy\ to\ pass\ the\ baton\ to\ Mahiya\ +\ Final\ Distance\ Travelled\ by\\ Mahiya\)Total Distance = 60 m + 120 m + 60 m = 240 m
Now, we will find the total time taken for this travelling. To find out the total time we will divide each distance travelled by the speed of the traveller during that distance:
\(Total\ Time = \frac{60\ m}{6\ m/s}+\frac{120\ m}{4\ m/s}+\frac{60\ m}{3\ m/s}\\\\Total\ Time = 10\ s\ +\ 30\ s\ +\ 20\ s\)
Total Time = 60 s
Now, we finally find the average speed of the baton by using the formula:
\(Average\ Time = \frac{Total\ Distance}{Total\ Time}\\\\Average\ Time = \frac{240\ m}{60\ s}\)
Average Speed = 4 ms⁻¹

As radiation from the sun reaches the earth, the energy is-
A ) Immediately radiated back into space.
B ) Absorbed by only the oceans
C ) Radiated, reflected, and absorbed
D ) Only reflected by clouds in the atmosphere
Answer:C
Explanation:All of the energy from the Sun that reaches the Earth arrives as solar radiation, part of a large collection of energy called the electromagnetic radiation spectrum. Solar radiation includes visible light, ultraviolet light, infrared, radio waves, X-rays, and gamma rays. Radiation is one way to transfer heat.
Answer: A) The amount of heat radiated from the atmosphere to the surface (sometimes called “back radiation”) is equivalent to 100 percent of the incoming solar energy.
B)On its northward journey, the water at the surface absorbs gases like carbon dioxide and chlorofluorocarbons (CFCs) – the latter are, to a large extent, the gases responsible for the ozone hole over Antarctica – as well as excess heat from the atmosphere
C)Water droplets and ice crystals that make up clouds scatter light equally at all wavelengths and therefore appear white. Reflection of solar radiation occurs when the radiation is sent directly backward from a surface. The fraction (or percentage) of radiation reflected back is known as albedo.
D)Clouds cool Earth's surface by reflecting incoming sunlight. ... Clouds warm or cool Earth's atmosphere by absorbing heat emitted from the surface and radiating it to space. Clouds warm and dry Earth's atmosphere and supply water to the surface by forming precipitation

List three evidences that show that the Bible is the Word of God.
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!

When an object such as a pendulum changes position its energy
Answer:
stays constant
Explanation
I kinda didn’t understand the question
A pendulum is a simple example of energy transfer. Beginning at position A, the pendulum fob is not moving. It has some energy because of its height (h) – called gravitational potential energy. When it is allowed to swing, that energy is gradually converted to energy of motion – kinetic energy.
What two gases in the atmosphere do animals and plants need to breathe and grow?
Answer: Explanation:
Plants and animals each produce the gases that the other needs to live. Plants need carbon dioxide—people and other animals exhale carbon dioxide as a waste product. People and other animals need oxygen—plants produce oxygen during an important process called photosynthesis, which turns the sun's energy into nutrients.

a. What is the period of the swing?
b. What is the frequency of the swing in hertz?
c. What is the amplitude of the swing?
Answer:
If it takes the swing 2 seconds to complete one cycle, then
that's the period of its motion ... 2 seconds.

Find in your house (or among your friends) either a pair of glasses or a magnifying glass. Examine it closely.
a. What kind of lens is it?
b. Draw a sketch of it and name the type of lens.
2. You will need a magnifying glass and a small piece of scrap paper for this demonstration.
a. Go outside on a sunny day and put the piece of paper on a patch of asphalt, concrete, or a large flat rock. Make sure there is no other combustible material or debris in the vicinity.
b. Hold the magnifying glass so it is close to the paper, with rays of sunlight shining through it. Move the magnifying glass side to side and close or away from the paper until the most concentrated ray of light is shining on the paper. This is the focal point for that magnifying glass.
c. Measure the distance between the focal point and magnifying glass. This is the focal length for that magnifying glass. (Be careful; if you hold the magnifying glass in that place for long enough, the paper will catch fire. Do not ever do this on your skin or clothing, as it can cause serious burns.)
d. Now take the magnifying glass inside and use it to look at the words in a book. What is the focal length now?

Erin is keeping a science journal. She wrote the following paragraph that explains how light travels through different mediums. But she’s made one mistake. Which sentence in Erin’s journal is incorrect?
A ray of light passes through the air and enters the water inside a metal container. The light ray bends as it crosses the boundary between air and water. Once it hits the bottom of the container, the ray gets reflected. The reflected ray passes back through the water and enters the air without bending. In this example, the ray of light is both reflected and refracted.
