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.

Which statement accurately describes in terms of energy what happens when water turns to steam?
The water releases energy which causes chemical bonds to break, changing water to steam.
The water releases energy which causes the water molecules to have less kinetic and potential energy, changing their configuration from liquid to gas.
The water absorbs energy which causes the water molecules to have more kinetic and potential energy, changing their configuration from a liquid to a gas.
The water absorbs energy which causes chemical bonds to break, changing water to steam.

Image shows a lake, a factory, a cloud in the sky, a cow, dead organisms, a tree, and the sun. An arrow from the sun to the tree is labeled A. An arrow from the sky to the tree is labeled B. The sky is labeled C above the cloud. The letter D is in the air and an arrow points from it down to dead organisms. An arrow points from dead organisms to the ground labeled E. An arrow points from the cow into to the sky labeled F. An arrow points from the factory to the sky labeled G. An arrow from the sky to the lake is labeled H above the lake.
Using the diagram above, match the description to the corresponding location in the carbon cycle model. Provide the letter only.
Carbon dioxide is converted to sugar used for food.
Carbon trapped in fossil fuels is converted to carbon dioxide.
Organic carbon is converted to fossil fuels.
Carbon dioxide is converted to carbonates.
Sugar is broken down and converted to carbon dioxide.

Images shows a lake labeled carbonates in water, a cow labeled animal respiration, a tree labeled photosynthesis, a factory labeled factory emissions, the sun labeled sunlight, a cloud labeled carbon dioxide in atmosphere, another tree labeled plant respiration, an arrow from organic carbon to dead organism, and fossils and fossil fuels. Arrows are labeled as follows: A from the sunlight to photosynthesis, B from carbon dioxide in atmosphere to photosynthesis, C from factory emissions to carbon dioxide in atmosphere, D from carbon dioxide in atmosphere to carbonates in water, E from dead organisms to fossils and fossil fuels, and F from plant respiration to the sky.
Using the diagram above, answer the following questions:
True or False. The arrow labeled C represents a transfer of chemical energy to mechanical energy. Explain why this is true or false.
True or False. The arrow labeled A represents a transfer of solar energy to chemical energy. Explain why this is true or false.
Which arrow or arrows represent a release of carbon dioxide? What process is occurring at the arrow(s) you selected?
Which arrow or arrows indicate a process that cycles carbon from living or nonliving organisms? Describe the process or processes you selected.
Which arrow or arrows represent reactions that demonstrate a conservation of mass and energy? Explain your answer.
Answer:
A - 1. Carbon dioxide is converted to sugar used for food (this is process of phosynthesis).
G - 2. Carbon trapped in fossil fuels is converted to carbon dioxide (this is combustion of fuel).
E - 3. Organic carbon is converted to fossil fuels.
H - 4. Carbon dioxide is converted to carbonates.
F - 5. Sugar is broken down and converted to carbon dioxide (this is breathing).

Answer:
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.

Claim 1 is the correct answer.
A student performs an exothermic reaction in a beaker and measures the temperature. If the thermometer initially reads 35 degrees Celsius, what is a possible reading of the thermometer after the reaction? A. 35 degrees Celsius B. 0 degrees Celsius C. 45 degrees Celsius D. 25 degrees Celsius
Answer:
C
Explanation:
Exothermic means that heat is released from the reaction
In Kevin’s favorite comic book, the superhero has special powers. In one adventure, the superhero must stop an evil villain who threatens to destroy the city with a powerful energy blast.
As he confronts the villain, he makes the following claims:
1: “I can create an energy force field to save the city.”
2: “I can destroy the energy before it destroys the city.”
3: “I can convert all the energy before it can do any harm to the city.”
4: “I can absorb all the energy and make it go away.”
If the superhero must obey the law of conservation of energy, which of the above can he actually do?
a. 1
b. 2
c. 3
d. 4
Answer:
3
Explanation:
The law of conservation of energy states that energy cannot just be created, so answer one is out. Energy also cannot be simply destroyed, so answer to is out as well. From here it gets tricky, since both answers make some sense under these rules. However, absorbed is bassically the same as destroying it leaving only answer three. Answer three does obey these laws, as energy can be converted.

When telescopes are looking at objects that are really far away, they are actually looking back in time.
True
False
Answer:
true
Explanation:
looking i the sky you can see stars that are billion years old
Time can be traversed via a telescope. Looking out into space is like looking back in time, according to NASA experts. Light needs time to traverse vast distances of space and come to Earth. Here the given statement is true.
The "deep" in Hubble Deep Field denotes the telescope's capacity to see some of these far-off, faint objects. It's like observing faraway space objects by going back in time. Even though light travels at an astounding rate, it still needs some time to cross the vastness of space.
Light travels slowly, so we don't see things as they are now, but as they were when they released the light that reached us from all over the galaxy.
Thus the given statement is true.

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.

(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.
