My question that i'm suppose the answer is: two particles, a and b, are in uniform circular motion about a common center. the acceleration of particle a is 6.0 times that of particle b. particle b takes 2.4 times as long for a rotation as particle a. what is the ratio of the radius of the motion of particle a to that of particle b?
the options are:
5: 1
1: 3
14: 1
1: 1
i'm very confused here because i don't understand how any of these choices can represent the answer. i know the acceleration of a is 6 times greater than b, and b takes 2.4 times longer to to complete a rotation compared to a. but how can i compare the motions, when it doesn't really give me anything to compare it to?

![a=\frac{\left[\frac{2 \times 3.14 \times R}{T}\right]^{2}}{R}=\frac{2 \times 3.14 \times R}{T^{2}} \rightarrow (3)](/tpl/images/0365/3313/408c6.png)

The slotted link is pinned at o, and as a result of rotation it drives the peg p along the horizontal guide. compute the magnitude of the velocity and acceleration of p along the horizontal guide. compute the magnitudes of the velocity and acceleration of p as a function of θ if θ=(3t) rad, where t is measured in seconds.

Awoman stands a distance d from a loud motor that emits sound uniformly in all directions. the sound intensity at her position is an uncomfortable 2.0×10-3 w/m2. at a distance 2.6 times as far from the motor, what are (a) the sound intensity and (b) the sound intensity level relative to the threshold of hearing?
