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.

I need help with this one
Answer:
Claim 1 is the correct answer.
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.
(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.

Explanation:
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.
