Physical science studies the relationships between __________, ___________, and ___________.
(GIVING BRAINLYIST) Jenna notices that the speed of the wind has increased throughout the day. What is causing the faster wind?
There has been no precipitation.
The difference in air pressure has decreased.
The difference in air pressure has increased.
The direction of the wind has changed to the south.
Answer: C. The difference in air pressure has increased.
The gases that move from high-pressure areas to low-pressure areas cause the high winds that we experience today. The bigger the difference between the pressures, the faster the air will move from the high to the low pressure.

WILL GIVE FREE BRAINLIEST EVERYDAY! DO NOT look up answers!! PLEASE FOLLOW DIRECTIONS ON THIS & FUTURE QUESTIONS OR WRONG!!! Question: What is a lewis Dot model, what is its purpose. And what are some REAL LIFE scenarios it is used in. also give me a description of where the creator is from and their name
Answer:
What is a Lewis Dot Model?
A simplified representation of the valence shell electrons in a molecule.
What is its purpose?
To show how the electrons are arranged around individual atoms in a molecule.
What are real life examples?
The Lewis Structures helps us understand the bonding of atoms and the shapes of molecules and their chemical properties. And in real life the proteins we eat in food are the carbohydrates which is from chemical bonding, which we can learn through TLS.
Creator of Lewis Structure Facts-
Gilbert Lewis Newton and he is from Weymouth, Massachusetts

You just learned that phase changes do not always happen in an expected way. If you were a professional scientist studying this situation, how would you go about investigating this phase change? What other questions would you ask?
Answer:
What I would do to understand more is understanding different ways that phase change happens. I would ask questions like, how does phase change happen in ways unexpected or what are different ways that phase change can occur.
Explanation:
Just ask your self questions about things that contribute to phase change that you don't already now about the topic. Until you now everything you want to know. And also some ways to talk about how phase change can be unexpected is ways you would think a middle school kid would not expect a way how phase change can occur. Hope this helps!
Why are rock samples from the Great Plains and from the Rocky Mountains composed of such similar minerals, when they look so different and come from different areas?
Answer:
The rock of the Great Plains is called sedimentary rock and the rock of the Rocky Mountains is called a igneous rock. A Sedimentary rock: is a type of rock that is formed by the buildup of mineral/organic particles at Earth's surface. And an Igneous rock: a type of rock that forms when magma (molten rock) cools/crystallizes. Since they formed in different ways they must not have formed together. Rocks can form in different ways, shapes sizes etc.. This causes them to be different types.
Explanation:
1) Sedimentary rock: type of rock that is formed by the accumulation or buildup of mineral or organic particles at Earth's surface.
2) Igneous rock: type of rock that forms when magma (molten rock) cools and crystallizes.
The North American Plate, on which both the Great Plains and the Rocky Mountains are situated, is a common tectonic plate.
What is rock?Rock is defined as a grouping of solid mineral grains that have grown or been cemented together. There are big rocks and little rocks. Rocks are created in the earth's crust. According to geology, rocks are produced when a combination of one or more minerals occurs. The sediments will eventually accumulate to such a high density that they will effectively turn into rock.
Although the Rocky Mountains' rock is volcanic and the Great Plains' rock is sedimentary, the two rock formations are stated to be different even though they contain comparable concentrations of specific minerals. Despite this, the two rocks have different formation processes.
Thus, the North American Plate, on which both the Great Plains and the Rocky Mountains are situated, is a common tectonic plate.

A student drank a bottle of water during a car ride up a mountain. At the top of the mountain, the student capped the plastic bottle. During the drive back down the mountain, what might happen to the bottle?
A) It will expand because the air is lower at the bottom of the mountain.
B) It will contract because the air pressure is higher at the bottom of the mountain.
C) It will become lighter. The air particles in the bottle weigh less because they are from the top of the mountain.
D) It will not change because it is empty and contains no air.

Please Help! What conclusions can you draw about how the amount of potential energy stored in system changes as a ball is placed at varying heights on a ramp? Write an evidence-based claim.
Answer:
The ball's potential energy in vertical circular motion depends upon the height of a ball concerning the referenced point at the bottom. Thus, the potential energy of the bowling ball moving in the vertical circular motion is maximum at the top concerning the bottom of the circular path.
Explanation:
What action-reaction forces are involved when a rocket engine fires? Why doesn't a rocket need air to push on?
Answer:
The action force is the rocket pushing out the "hot" gases produced by the engine. The reaction force is the hot gas pushing back on the rocket propelling it into outer space.
And....
The reaction force is the hot gas pushing back on the rocket propelling it into outer space. There is no need for air to push on because the hot gases produced by the rocket allow the action and reaction forces to operate. These two forces are equal and opposite (action-reaction) forces.
