1. Problem, purpose, or research question: The problem or research question is the single most important part of the scientific method. Every part of your project done to answer this question. The research question is sometimes formed as a statement and is called the "problem" or "problem statement"
Answer:
I don't know if it's fair for me to write an entire essay for you
but if you would like I can list some reasons you can incorporate into an essay.

-If you are joining a gang you are most likely going to have a greater chance of being targeted, even if it seems like you would be protected.
-Most of the time when someone joins a gang a child is being separated from a parent and will face most aggression.
-This can also cause academic failure in students, from lack of education and probably a pretty bad background.
-For teens when joining a gang they will do things that aren't suited for their age (I would list things but I'm not trying to get myself reported if you know what I mean)
-You will also have a great risk of being imprisoned and facing bad consequences, and these consequences can even be having the death penalty.

I hope this is good enough, sorry I didn't give you a full essay. I think this should help with that though.
The important thing to note here is the direction of motion of the test rocket. Since it mentions that the rocket travels vertically upwards, then this motion can be applied to rectilinear equations that are derived from Newton's Laws of Motions.These useful equations are:
y = v₁t + 1/2 at²
a = (v₂-v₁)/t
where
y is the vertical distance travelled
v₁ is the initial velocity
v₂ is the final velocity
t is the time
a is the acceleration
When a test rocket is launched, there is an initial velocity in order to launch it to the sky. However, it would gradually reach terminal velocity in the solar system. At this point, the final velocity is equal to 0. So, v₂ = 0. Let's solve the second equation first.
a = (v₂-v₁)/t
a = (0-30)/t
a = -30/t
Let's substitute a to the first equation:
y = v₁t + 1/2 at²
49 = 30t + 1/2 (-30/t)t²
49 = 30t -15t
49 = 15 t
t = 49/15
t = 3.27 seconds
A wave is a perturbation in a material from the point the perturbation was produced, to the sorrounding area
Limestone and dolomite are the rocks present in the locations which leads to the formation of caves.
<h2>Formation of caves</h2>
The type of rocks that once existed in these locations are limestone and dolomite whereas the pH of the nearby groundwater is slightly acidic which is responsible for the formation of caves. Caves are formed by the dissolution of limestone due to acid rain.
<h3>Acid rain</h3>
Rainwater reacts with carbon dioxide from the air and percolates through the soil, which turns into a weak acid. This slowly dissolves out the limestone which become turn to form caves so we can conclude that Limestone and dolomite are the rocks present in the locations which leads to the formation of caves.
