Which describes a velocity?
A. Speed changing from 2 km/hr to 5 km/hr
B. Moving north at 40 km/hr
C. Flying at 200 miles/hr
D. Moving 8 meters in 2 seconds
Answers
Answer: B
Explanation:
Velocity is the speed of an object but in a particular direction.
If you look, answer choices A, C, and D, all give certain speeds, but they don't give any direction, like north east west or south. Only B gives the speed in a particular direction (north).

Which of the following forces has not changed Earth's surface?
folding
erosion
weathering
gravity
Answers
Answer:Gravity is the force among the options listed that has not directly changed Earth's surface.
Explanation:
Gravity is a fundamental force that acts on all objects with mass, including the Earth itself, but it does not cause changes or modifications to the Earth's surface features. Instead, gravity influences the movement of materials and the shape of the Earth's surface by exerting a pulling force on objects. On the other hand, folding, erosion, and weathering are all processes that directly contribute to shaping
Earth's orbit is an ellipse. Which of the following ellipses most closely resembles the exact shape of Earth's orbit, as seen from directly above the North Pole?
Answers
Earth is revolving around the sun in an elliptical orbit, with sun as one of its focus. So, the correct shape is A.
What is Newton's law of gravity ?Newton's law of gravity states that, every body in the universe attract each other with a force directly proportional to the product of their masses and inversely proportional to the square of the distance between them.
Here,
Earth is revolving around the sun in an elliptical orbit, with sun as its focus.
According to Kepler's law of orbits, every planet moves in an elliptical orbit with sun as one of its focus.
From, Newton's law of gravity and Kepler's law of orbital motion, we can say that the earth is moving in an elliptical orbit because, the earth is experiencing gravitational force of attraction due to the sun at the centre and also due to the other planets revolving in the solar system.
Due to the overall gravitational force, the earth will have to adjust the orbital motion in order to attain stability. As a result, the orbit of earth will have a distortion from its circular shape, forming an elliptical shape for orbit, which is a stable shape.
Hence,
Earth is revolving around the sun in an elliptical orbit, with sun as one of its focus. So, the correct shape is D

What would happen to the digestion process if enzymes were not present
Answers
Answer: It would take 2.3 billion years for the biological reaction without the presence of enzymes. It’s because, without them, your body can’t break down foods so that nutrients can be fully absorbed. Every organ, every tissue, and every 100 trillion cells in our body rely upon the reaction of metabolic enzymes and their energy component.
Explanation:
I hope this helps
Without enzymes, the body would not be able to break down complex carbohydrates, proteins, and fats into their component molecules. This means that these nutrients would not be absorbed by the body and would be excreted as waste.
Additionally, the lack of enzymes would make it difficult for the body to digest and absorb vitamins and minerals. This could lead to malnutrition and other health problems over time.
Overall, the absence of enzymes from the digestive process would severely impair the body's ability to extract nutrients from food and could have negative consequences for overall health and well-being.

Explanation:
sea level is another way of saying zero. If something is above or above sea level it is a positive integer. like a regular number. if something is below sea level it is a negative integer like negative numbers. They said 8 is the elevation but new orleans is BELOW sea level. that means the integer we are looking for is going to be a negative number. 8 is the number they told us and since it is below the sea level. The integer of new orleans that represents its elevation is -8.

Answers
Answer: The human circulatory system can be arranged from the highest to the lowest degree of internal organization as follows: Heart, Blood Vessels, Arteries, Veins, and Capillaries.
Explanation: The human circulatory system can be arranged from the highest to the lowest degree of internal organization as follows:
Heart: The heart is a vital organ responsible for pumping oxygenated blood to the body and deoxygenated blood to the lungs. It consists of chambers (atria and ventricles) and valves that regulate blood flow.
Blood Vessels: Blood vessels form a network of tubes that transport blood throughout the body. They can be classified into three types: arteries, veins, and capillaries.
Arteries: Arteries are thick-walled blood vessels that carry oxygenated blood away from the heart to various parts of the body.
Veins: Veins are blood vessels that transport deoxygenated blood from the body back to the heart. They have thinner walls compared to arteries and contain valves to prevent backflow.
Capillaries: Capillaries are tiny, thin-walled blood vessels that connect arteries and veins. They facilitate the exchange of oxygen, nutrients, and waste products between the blood and surrounding tissues.
Please note that this arrangement is based on the internal organization of the circulatory system, with consideration given to the hierarchical structure and function of each component.

Black to move and capture a hanging piece . Select the best move
A) Nxg3
B) Bxg3
C) Qxg5
Answers
Answer: A
Explanation:The Pawn moves directly forward, never backward or to the side. Pawns capture a piece that is one square diagonally forward. Though Pawns normally cannot move diagonally, this is the only way they capture.
Based on the information provided, the best move to capture a hanging piece would be: A) Nxg3
What would be the best move to capture a hanging piece ?Nxg3 would be the best move to capture a hanging piece.
This move involves sacrificing the knight to capture the hanging piece, which could be a bishop or pawn, depending on the position of pieces. After Nxg3, the opponent may capture the knight with different piece, but the player who made the move will have successfully captured the hanging piece.
However, it's important to note that the best move ultimately depends on the overall strategy of the player and the position of the other pieces on the board.

The forces were balanced when the car was parked. The forces stayed balanced when it moved.
The forces were unbalanced when the car was parked, and two or more forces changed. The forces stayed unbalanced and caused the car to move.
Answers
Answer:
A (the first one)
Explanation:
An object is stationary when both forces acting on it are balanced. As soon as the car started moving, the driver had placed extra force on the accelerator and therfore the forces became unbalanced and the car moved
Using the Newton's law of motion to make conclusion about the scenario, the correct option would be ; The forces were balanced when the car was parked, but one or more forces changed. The total forces became unbalanced, causing it to move.
According to Newton's law, it states that a body will continue in a state of uniform motion or rest unless it is acted upon by a force to make it act otherwise "
A parked car is in a state of rest, which means that the net force acting on the car is 0. This denotes that, it is acted upon by a balanced force. The movement of the car denotes that, the force in one direction is higher than the other forces (unbalanced forces) , hence, making the car move in the direction of the greater force.Therefore, the forces were balanced when the car was parked, but one or more forces changed. The total forces became unbalanced, causing it to move.
