Answer:
sunlight in deeper location decreases
Explanation:
because the more salinity water has the harder it is to see and the harder it is for light to travel through the ocean
sunlight in deeper locations decreases, This event may occur when ocean salinity increases. Hence option C is correct.
What is sunlight ?Sunlight is a kind of electromagnetic radiation emitted by the Sun, namely infrared, visible, and ultraviolet light. When the Sun is above the horizon, sunlight is scattered and filtered through the Earth's atmosphere and appears as daylight. Sunlight, a mix of brilliant light and radiant heat, is experienced when direct solar radiation is not hindered by clouds. Sunlight is dispersed when it is obstructed by clouds or reflected off other things. According to sources, a worldwide average of between 164 and 340 watts per square metre over a 24-hour day is estimated by NASA to represent roughly a fifth of the Earth's typical total sun irradiation.

List an example of matter in each of the three states.
The example of matter in the three states is brick in solid state, water in liquid state and oxygen gas in gaseous state.
1. Solid: A brick is a solid object that maintains a fixed shape and volume.
2. Liquid: A glass of water is a liquid that conforms to the shape of its container but maintains a definite volume.
3. Gas: Oxygen gas in the atmosphere is a gas that does not have a fixed shape or volume, filling the available space.
The three states of matter are solid, liquid, and gas. Solids have a fixed shape and volume, such as an ice cube. Liquids have a definite volume but take the shape of their container, like water. Gases have neither a fixed shape nor volume and fill the entire space available to them, such as the air we breathe.
In summary, the states of matter describe the physical properties of substances based on the arrangement and movement of their particles, with solids having a fixed shape, liquids taking the shape of their container, and gases being free-flowing and filling all available space.

Solid: An object that keeps a constant shape and volume is a brick.
Thus, Liquid: A glass of water is a liquid that keeps a consistent volume while taking on the shape of its container. Gas: Oxygen gas fills the available space in the atmosphere and does not have a defined shape or volume.
Gas, liquid, and solid matter can exist in any combination. Solids, like an ice cube, have a set shape and volume.
Like water, liquids have a set capacity but adopt the shape of their container. Gases, like the air we breathe, have neither a set shape nor volume and fill all available space.
Thus, Solid: An object that keeps a constant shape and volume is a brick.

Any atom which no longer has a neutral charge is called a blank
Answer:
atoms that no longer have a neutral charge are called ions!
Explanation:
when atoms gain or lose electrons, they become either negatively charged or positively charged in the process. losing electrons means the atom becomes more positive, therefore positively charged. gaining electrons means the atom becomes more negative, so negatively charged. atoms that go through this process of gaining or losing electrons are called ions.

why is it difficult for a car to round a curve at high speed
Answer:
Because the force required to produce this acceleration equals the mass of the car x acceleration, the group of the car is the same but the acceleration is a lot more hence a much bigger force is required. So this is why it's harder for cars to corner at a high speed rather than lower.
Answer:
Vehicles are heavy and have a lot of inertia. This means that if you drive too fast on a curve, your vehicle will keep going straight instead of going around the curve, no matter how hard you drive or slow down to keep it in your lane. Centrifugal force creates a strong outward pull on your vehicle. So all you need to do is slow down before entering a corner. Reducing your speed when you are already on a bend can cause your car to skid.
which statement describes how adding oil effects the mechanical efficiency of a car's engine?
Answer:
Mechanical efficiency accounts for losses due to engine friction and ancillaries such as the lubricant pump, coolant pump, fuel pump and cooling fan. Engine friction arises whenever there is relative motion between parts. Journal bearings on the crankshaft, connecting rods and camshaft as well as piston rings and piston skirts are important sources
Explanation:
Determine the kinetic energy of a 10 Kg roller coaster car that is moving with a speed of 2m/s.
In this question all required information's are already provided. Based on these details the answer to the question can be easily determined. Let us now write down all the information's that are already given.
Mass of the roller coaster = 1000 kg
Velocity of the roller coaster = 20.0 m/s
We know the formula for finding the kinetic energy is
Kinetic energy = 0.5 * mass * (velocity) ^2
= 0.5 * 1000 * (20)^2
= 0.5 * 1000 * 400
= 200000 Joules
So the Kinetic energy of the roller coaster is 200000 joules.

If the line on a distance versus time graph and the line on a speed versus time graph are both straight line going through the origin, can the two graphs be displaying the motion of the same object?
Answer:
No they cannot
Explanation:
A straight line going through the orign in a distance versus time graph would show that the object is going at a constant speed, meaning that the speed is not changing.
A straight line going through the origin in a speed versus time graph would show that the object is accelerating at a constant rate, or that it's speeding up/slowing down at a constant rate
It is true that if the line on a distance versus time graph and the line on a speed versus time graph are both straight lines going through the origin, then the two graphs can display the motion of the same object
Distance versus Time Graph: If the line on the distance versus time graph is a straight line, then the object's distance is proportional to the time. The object is traveling at a constant speed. The slope of this line shows the speed of the item.
Speed versus Time Graph: If the line on the speed versus time graph is likewise a straight line through the origin, the object's speed remains constant over time. The slope of this line denotes the object's acceleration.
Yes, if the line on a distance against a time graph and the line on a speed versus time graph are both straight lines through the origin, they can represent the motion of the same item.
Hence, it is true that if the line on a distance versus time graph and the line on a speed versus time graph are both straight lines going through the origin, then the two graphs can display the motion of the same object

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!

A force that will work against motion in every situation is —
Answer:
Friction
Explanation:
There are some forces that will work against the motion in every situation, the force of air resistance is often observed to oppose the motion of an object, Frictional Force, Gravitational Force, Normal Force, Magnetic Force, and Tension Force.
What is Force?Force is the influence of either pull or pushes in the body. Basically, gravitation forces, nuclear forces, and friction forces are the types of forces. For e.g. when the wall is hit by a hand then a force is exerted by the hand on the wall as well as the wall also exerts a force on the hand. There are different laws given to Newton to understand force.
Newton is a unit of force used by physicists that is part of the International System (SI). The force required to move a body weighing one kilogram one meter per second is known as a newton.
Therefore, the force of air resistance is often observed to oppose the motion of an object, Frictional Force, Gravitational Force, Normal Force, Magnetic Force, and Tension Force.
