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

Answer:
n the case of linear motion, the change occurs in the magnitude of the velocity, the direction remaining constant.
In the case of circular motion, the magnitude of the velocity remains constant, the change in its direction occurring.
Explanation:
Velocity is a vector therefore it has magnitude and direction, a change in either of the two is the consequence of an acceleration on the system.
In the case of linear motion, the change occurs in the magnitude of the velocity, the direction remaining constant.
= (v₂-v₁)/Δt
In the case of circular motion, the magnitude of the velocity remains constant, the change in its direction occurring.
= v2/R
In the general case, both the module and the address change
a = Ra ( a_{t}^2 + a_{c}^2)
Answer:
The angular displacement would be 6 Pi radians or 1080 degrees.
Explanation:
Every individual rotation is 2 Pi (this applies to anything regardless of radius).
Since there are three rotations you are going to multiply 2 Pi by 3.
This will give you 6 Pi which you can convert to equal 1080 degrees (1 Pi = 180 degrees).
