Explanation:
the circulatory system is things like veins which transport blood cells through the body
the digestive system is things like your stomach and esophagus which digests food and turns it into energy
the respiratory system is things like lungs, which moves air through your body
and the skeletal system is things like bones, which help you move but also protect vital organs

Explanation:
(a) After the engines stop, the rocket reaches a maximum height at which it will stop and begin to descend in free fall due to gravity.
(b) We must separate the motion into two parts, when the rocket's engines is on and when the rocket's engines is off.
First we must find the rocket speed when the engines stop:
This final speed is the initial speed in the second part of the motion, when engines stop until reach its maximun height. Therefore, in this part the final speed its zero and the value of g its negative, since decelerates the rocket:
So, the maximum height reached by the rocket is:
(c) In the first part we have:
And in the second part:
So, the time it takes to reach the maximum height is:
(d) We already know the time between the liftoff and the maximum height, we must find the rocket's time between the maximum height and the ground, therefore, is a free fall motion:
So, the total time is:
Ultraviolet has a shorter wavelength than microwaves, so purple also has a shorter wavelength than red.
C is thus the answer
You haven't included the list of choices that goes with the question, so it's

Regarding my ability to answer the question and collect the 5-point bounty,
I'm free to make up any phrase of my own that correctly describes an atom.
-- very very very very very very very tiny
-- includes even tinier particles, with electric charges
both positive and negative
-- smaller than the wavelength of visible light
