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

How does the scientific meaning of the words work, energy, force and efficiency compare to their every day meaning? State the similarities and differences? need answer asap. Thank you!
Answer:
Force
If you're taking classical physics, simply stated, a force is a push or a pull of some sort. But there is one other very important thing to understand about Force. A true Force is always an interaction (at least from a classical perspective). That means that forces always come in pairs. This is stated in Newton's Third Law (equal and opposite forces). Every action must have a reaction. This is required for all true forces. Another consequence of this is that force is a vector, meaning it has a magnitude and a direction. The action and reaction will always be opposite in direction.
A lot of people will say F=ma. This is true. However, it is important to keep in mind that this definition is a calculational tool. It is more precise to say the Sum of all forces=ma. The point is that ma is not a force. Forces are things like weight, tension, normal, friction, gravity, electrostatic, magnetic, and various other applied forces. The sum of forces on an object equals the product of its mass times its acceleration.
It is important to keep in mind that the force is on the object that accelerates. Another way to state this is that objects cannot accelerate themselves. You cannot push yourself back (or forwards). But if you push a heavy object like a desk forwards, then the desk can push you back.
Energy
There are many kinds of energy. There are two important things to know.
Energy is the ability to do work. It doesn't mean work is being done, but that work can be done. (So you can see there is an intimate relationship between work and energy).
Energy is conserved. That means the total amount of energy is always constant. If the energy is a system changes somehow, that means some work was done in order to move the energy from one system to another.
Energy is also a scalar (given that Work is a scalar).

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.
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!

Describe the two characteristics of the general surface wind circulation pattern associated with this low-pressure system
Which location on the map, W, X, Y, or Z, most likely has the greatest wind speed? Describe one piece of evidence on the map indicating that this location has the greatest wind speed.
Answer: I would Say X.
Explanation: I say this because the numbers are higher near X. I'm not sure because the map does not say much. Hope this helped. Have A Good Day!!!
The wind speed is highest at point X, due to high pressure area and counterclockwise flow.
The given problem is based on the wind circulation system. In climatology, the wind circulation system is referred to as the movement of air relative to the surface of Earth. The characteristics of the general wind circulation pattern associated with low-pressure system is as follows:
The Wind flow will be towards the low pressure region, and the air rises in the atmosphere.As air rises, the moisture gets into condensation and clouds are formed along with the precipitation.The evidence for determining the greatest wind speed is that, "Wind moves counterclockwise around low-pressure area and clockwise around the high-pressure area". Now, the pressure and speed for the wind is,
\(P=\dfrac{1}{2} \rho v^{2}\)
here, P is the pressure and v is the speed of wind. So, higher the pressure, higher will be speed.
As per the given map, point X represents the area of counterclockwise movement of wind, so probably it should have high pressure, hence speed is higher at point X.
Thus, we can conclude that the wind speed is highest at point X, due to high pressure area and counterclockwise flow.

A cart is loaded with a brick and pulled at constant speed along an inclined plane to the height of a seat-top. If the mass of the loaded cart is 3.0 kg and the height of the seat top is 0.45 meters, then what is the potential energy of the loaded cart at the height of the seat-top?
The potential energy of the cart loaded with a brick and that is pulled at constant sped along an inclined plane to a height of 0.45 meters, is 13.24 J.
At the height of the seat-top, the potential energy is given by:
\( E_{p} = mgh \)
Where:
g: is the acceleration due to gravity = 9.81 m/s²
m: is the mass of the loaded cart = 3.0 kg
h: is the height = 0.45 m
Hence, the potential energy is:
\( E_{p} = mgh = 3.0 kg*9.81 m/s^{2}*0.45 m = 13.24 J \)
Therefore, the potential energy of the loaded cart at the height of the seat-top is 13.24 J.

Can please tell what mistake I did??question number 10
Explanation:
When we draw the diagram of the motion we get a right angled triangle.
We have an angle of 30° and a base of 17.3M.
We will use trigonometric ratios to solve this.
We will use tan.
Tan = Opposite / adjacent
Tan 30° = h / 17.3
h = Tan 30 × 17.3
h = 0.5774 × 17.3 = 9.99 M
or 9.99 can be roundoffed with 10m

3.) The atoms inside of a __________ are not allowed to move around too much.
Answer:
1. plasmas
2. special physical forces.
3. solids.
you are most welcome! :D
Answer:
Refer to the explanation.
Explanation:
1.) Plasma is a lot like gases, but the atoms are different because they are made up of free electrons and ions of the element.
In a gas, the atoms or molecules are mostly neutral and not ionized. However, in plasma, the gas is ionized, meaning some or all of the atoms have gained or lost electrons, resulting in the presence of free electrons and ions. These free electrons and ions make plasma distinct from gases and give it unique properties, such as the ability to conduct electricity and respond to magnetic fields.2.) Elements and compounds can move from one phase to another phase when special conditions or factors (such as temperature, pressure, or the addition/removal of heat energy) are present.
The phase of a substance refers to its physical state, such as solid, liquid, or gas. The transition between these phases can occur under specific conditions. Generally, substances change phase when certain thresholds of temperature and pressure are reached, but other factors can also play a role. For example, when a solid is heated to a certain temperature (its melting point), it can transition to a liquid phase, and further heating can turn it into a gas. Similarly, changing pressure can cause phase transitions, such as when a gas is compressed to a certain pressure, causing it to condense into a liquid.3.) The atoms inside of a solid are not allowed to move around too much.
In a solid, the atoms or molecules are tightly packed and held together by strong intermolecular forces. This close arrangement and strong bonding restrict the movement of atoms or molecules, keeping them relatively fixed in their positions. While atoms in a solid can still vibrate around their equilibrium positions, they generally do not have enough energy to move freely throughout the substance like in liquids or gases. This lack of mobility gives solids their characteristic rigidity and shape.What does your body use to replace tissues and organs?

\(2.613\:\cdot10^5\) Joules ; 5. Adding the same amount of heat to two different objects will produce the same increase in temperature ; 2. Same speed in both ; 2. A
Explanation:
Diagram 1 ( Liquid Nitrogen ) : So as you can see, we want our units in Joules here, and can therefore multiply the mass of gaseous nitrogen and the latent heat of liquid nitrogen, to cancel the units kg, and receive our solution - in terms of Joules. Let's do it.
q ( energy removed ) = mass of nitrogen \(*\) latent heat of liquid nitrogen,
q = 1.3 kg \(*\) 2.01 \(*\) 10⁵ J / kg = \(1.3\:\cdot \:2.01\:\cdot \:\:10^5\) = \(10^5\cdot \:2.613\) = \(100000\cdot \:2.613\) = \(261300\) Joules = \(261.3\) kiloJoules = 2.613 \(*\) 10⁵Joules is the energy that must be removed
Diagram 2 : The same amount of heat does not necessarily mean the same increase in temperature for two different objects. The increase in temperature depends on the specific heat capacity of the substance. Therefore your solution is 5 ) Adding the same amount of heat to two different objects will produce the same increase in temperature.
Diagram 3 : The temperatures in both glasses are the same, and hence the molecules have the same average speed. Therefore your solution is 2 ) Same speed in both.
Diagram 4 : Glass A has more water molecules, and hence has more thermal energy. Your solution is 2 ) A.
