Velocity of bicycle is 5 m/s towards north
radius of rim 
mass of rim 
Angular momentum 


direction of Angular momentum will be towards west
Answer:
If two forces act on an object in the same direction, the net force is the sum of the two forces. In this case, the net force is always greater than either of the individual forces.
Answer:
The answer should be A) 0m/s

Please tell me if I am wrong because I'm not 100% sure on this. Hope it's right and that it helped you.
Answer:

Explanation:
= Maximum charge stored by capacitor = 6 μC = 6 x 10⁻⁶ C
= time taken for charge on the capacitor to become zero = 2 ms = 2 x 10⁻³ s
Time period is given as



Angular frequency is given as


=785 rad/s
Charge at any time is given as

Taking derivative both side relative to "t"


Amplitude of the current is given as



A larger amplitude means a smaller sound and a smaller amplitude means a larger sound.
