Answer:
In SPIRAL MOTION a body rotates on its own axis (passing through it) while in CIRCULAR MOTION any body/particle moves on a circular path with center outside the body.

Answer:
The correct option is;
Technician A
Explanation:
Here we note failure analysis will assist in determining the cause of failure and as such to determine the cost effectiveness of a repair or a replacement.
However, a warranty is a legal contract between the buyer of the engine and the manufacturer for the manufacturer to either repair the engine or compensate the the customer for all failures that occur within the period of the warranty. Therefore, technician B is not correct as he says the manufacturer may request the engine for analysis on why it failed which is not the same as the basis of a warranty.
(a) The angular speed of the rotation is 12.57 rad/s
(b) The period of the rotation is 0.5 s.
(c) The speed of the tip of your finger is 15.08 m/s.
<h3>
Angular speed of the rotation</h3>
The angular speed of the rotation is calculated as follows;
ω = 2πN
where;
- N is number of revolutions
ω = 2π x (2) = 4π = 12.57 rad/s
<h3>Period of rotation</h3>
<h3>Speed of your finger</h3>
v = ωr
v = 12.57 x 1.2
v = 15.08 m/s

Use the velocity expression for uniform acceleration and solve for t: v = v0 + at. v0 is zero since the object is at rest. 49 m/s = a(t), and solve for t. t = 49 m/s / 9.8 = 5 seconds.
