Answer:
(A) Torque required is 21.205 N-m
(b) Wok done will be equal to 1199.1286 j
Explanation:
We have given moment of inertia
Wheel deaccelerate from 135 rpm to 0 rpm
135 rpm =
Time t = 8 sec
So angular speed and
Angular acceleration is given by
Torque is given by torque
Work done to accelerate the vehicle is
Answer:
The force will be doubled.
Explanation:
Just looking at the situation,
<em>We are supposing the distance in between these charges is the same in both the cases which is r</em>, so for the first normal case,
, q1, q2 are the two charges and r is the distance between them.
Now take the other case when the the Charges are doubled,
you can see clearly from the above equation that the new force which is has been doubled.
I hope it helps,
Thank you.
Answer:
Hi I hope this is correct!
Explanation:
You can use this formula to solve this question T = mv^2/R
m = 0.3 kg , v = 6.0 m/s , R = 1.5 m
T = (0.3 kg)(6.0 m/s)^2 / 1.5 m
= 7.2 Newtons
Hope this helps! Best of luck <3
