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.
Answer:
The resistor to be hooked up must be 9900
Explanation:
Recall how resistors in parallel combine to render an equivalent resistor:
So we need to find which resistor (R2) we need to combine in parallel with resistor R1 (100 ) in order to obtain an equivalent resistor Re (99
