The wire vibrates back and forth between the poles of the magnet.
The frequency of the vibration is the frequency of the AC supply.
The answer is 789.25 which you’d subtract 2011.25-122.2 I think sry if I’m wrong
Answer:
The detailed calculations are shown below;
Explanation:
a)The maximum acceleration of the particle:
It is seen that the maximum change in velocity is at the time between 8s to 10s.
Maximum acceleration: 
= 
= 10 m/
b) The deceleration of the particle
The velocity of particle is decreased after 10s so,
deceleration = - 
= - 6.67 m/
c)The total distance traveled by the particle = Area under the curve
=
* 4*20 + 4*20 +
* 2*20+ 2*20+
* 40*16
= 290 m
d)The average velocity of the particle = 
= 
= 18.12 m/s
Answer:
False.
Explanation:
Mechanical waves require a medium in order to transport their energy from one location to another.
