Hello!
My best guess would be hydrogen and oxygen.
hopefully this helps!
answer:
thank youu for the points cute drawing by the way (✿◠‿◠)
when did you join brainly though?
have a wonderful dayyy !!
Answer: A volcanic island arc like Hawaii.
Explanation: The Hawaiian island is the most safest place for the people to live in comparison to the other given options.
The plate tectonic movement generates energy due to collision, resulting in sudden release of energy, and seismic waves are produced that propagates and causes earthquake.
Due to the constant collision between the plates, different places at different time experiences earthquake. Near a fault region, earthquakes are very severe, and also near the mid oceanic ridge it is not possible for a person to live. The subduction zones are the region where a denser plate subducts beneath the other, and its impossible for life to exist there.
Thus the most safest place out of all the option is the volcanic islands where numerous people resides. for example, the Hawaiian and Stromboli.
Answer: D(t) = 
Explanation: A harmonic motion of a spring can be modeled by a sinusoidal function, which, in general, is of the form:
y = 
or y = 
where:
|a| is initil displacement
is period
For a Damped Harmonic Motion, i.e., when the spring doesn't bounce up and down forever, equations for displacement is:
or 
For this question in particular, initial displacement is maximum at 8cm, so it is used the cosine function:
period =
12 =
ω = 
Replacing values:
The equation of displacement, D(t), of a spring with damping factor is .
Rotational speed of an object around an axis is the numbers of turns of the object divided by time. <span />
