For the 1st question, it is the pickup truck.
Explanation:
Even though they are the same speed, the pickup truck is curving. So, I think it changes velocity.
Answer:
For the 2nd question, it is B.
Explanation:
Accelaration is either slowing down, speeding up, or changing direction. However, B is in a straight line. So, it must be B.

NEED THIS ANSWER SOONER THAN ASAP!!! HELP PLZ!! Explain how the concepts of energy transformation and conservation of energy allow you to track how energy moves through a system.
Answers
The law of conservation of energy states that energy can neither be created nor be destroyed, but it can be transformed from one form to another.
So I considered an example of it as follows: water is stored at height with potential energy, the water flows, and its potential energy is converted into kinetic energy. It flows to rotate a turbine with mechanical energy. Then the kinetic energy is converted into electrical energy. In our house, the electrical energy is converted into luminous energy, heat energy, and so on.
But what happens after that?
Explanation:
In summary, the concepts of energy transformation and conservation provide a powerful framework to understand how energy moves through a system, how it changes forms, and how to ensure that the total energy remains constant throughout the process.
Energy transformation refers to the process of converting energy from one form to another. In any system, energy can exist in various forms, such as kinetic energy (energy of motion), potential energy (energy due to position or configuration), thermal energy (heat), chemical energy (stored in chemical bonds), electrical energy, etc. As energy moves through a system, it can undergo transformations, changing from one form to another.

Potential energy increases but kinetic energy stays the same during a roller coaster ride.
Kinetic energy and potential energy change, but energy is neither created nor destroyed during a roller coaster ride.
Potential energy is destroyed during a roller coaster ride.
Kinetic energy is created during a roller coaster ride.
Answers
A)Potential energy increases but kinetic energy stays the same during a roller coaster ride.
Explanation:
Potential energy is stored energy that depends upon the relative position of various parts of a system.
Kinetic energy is a form of energy that an object or a particle has by reason of its motion

Why have ice ages come and gone?
Answers
Answer:
"When less sunlight reaches the northern latitudes, temperatures drop and more water freezes into ice, starting an ice age. When more sunlight reaches the northern latitudes, temperatures rise, ice sheets melt, and the ice age ends."
Explanation:
Answer:
As temperatures decrease, less sunlight reaches the water. This causes the ice to freeze, when this happens in mass it causes an ice age. Later, temperatures rise and the ice melts.
Explanation:
Temperatures plummet as less sunlight reaches northern latitudes, and more water freezes into ice, triggering an ice age. Temperatures rise, ice sheets melt, and the ice age ends as more sunshine reaches northern latitudes.

I have no idea what this is about, I keep reading it over and other again, but I still don't understand! Help?
Answers
Answer:
A
Explanation:
So, here's a slightly simpler example:
If i had a jar, and i added sand, then rocks on top of the sand, and finally dirt on top of everything, what would the layers of the jar look like? (Assuming that i hadn't shaken the jar)
Well, the answer would be: The bottom of the jar would be a sand, the middle would be rocks, and on top would be dirt.
This question is pretty much the same question, just with fancier words and 4 things instead of 3
If the stars come first, then you find them at the very bottom of the jar. if the squares come second, then they are above the stars, but below the triangles, which come third. The circles come last, so you find them last. Thus the order is: stars, squares, triangles, and circles, from bottom to top, so it's A
Note: the jar represents the earth, and it too, may be shaken up in some places. This means that sometimes, if two organisms lived very close together in time (like the star and the square), and some event happened, you may occasionally see the square below the star. However, this question says that they weren't disturbed.
Nirates and phosphates are important chemicals to living things. Explain why these chemicals can also be pollutants.
Answers
Answer:
Nitrogen and phosphorus are essential elements for all living organisms. They are used in DNA and chemical processes in the body. Most nitrogen is found in the air and most phosphorus is bound up in rocks and sediments, making them unavailable to organisms. And they are pollutants cuz nitrogen and phosphorus support the growth of algae and aquatic plants, which provide food and habitat for fish, shellfish, and smaller organisms that live in water. But when too much nitrogen and phosphorus enter the environment - usually from a wide range of human activities - the air and water can become polluted
Explanation:
if my answer help, I hope you get better <3
Explanation:
When nitrate and phosphate ions concentrations in shallow waterbodies are in excess, there is overgrowth of water plants leading to the formation of algal bloom. This causes a high consumption of dissolved oxygen in the water. ... The dead plants and animals decay creating deterioration of water quality.
