Explanation:
The given data is as follows.
Angular velocity (
) = 2.23 rps
Distance from the center (R) = 0.379 m
First, we will convert revolutions per second into radian per second as follows.
= 2.23 revolutions per second
= 
= 14.01 rad/s
Now, tangential speed will be calculated as follows.
Tangential speed, v = 
= 0.379 x 14.01
= 5.31 m/s
Thus, we can conclude that the tack's tangential speed is 5.31 m/s.
It depends on which side. Opposites attract, so north and south would attract to each other and collide, while north and north or south and south would go away from eachother.
Answer:
A negative
when the charged rod is brought closer to the sphere negative charges get induced on the surface of the sphere by gathering some electrons from the ground and the negative charges reamain on the sphere even after disconnecting it. here the ground acts as a reservoir of electrons.
<span>The inertia of an object increases if the mass is decreased. Inertia is the resistance of any physical object to a change in its state of motion or rest. It is represented numerically by an object's mass.</span>
