Answer:
ac = 124.6 m/s²
Explanation:
When an object executes a uniform circular motion, acceleration is produced in it due to a change in its direction during the motion. This acceleration is called the centripetal acceleration. The formula used to find this acceleration is given as follows:

where,
ac = centripetal acceleration = ?
v = speed = 9 m/s
r = radius = 0.65 m
Therefore,

<u>ac = 124.6 m/s²</u>
Yes it is a force omg so smart
Electric current is defined as charge per time in units of Coulombs/second
So we have
I=5.6C/15.4s = 0.3636A
Smallerrrrrrrrrrrrrrrrrrrrrrrro
