Explanation:-Electromagnetic induction:-

It is a phenomenon of producing induced current in a coil by changing the magnetic feild around the coil is called Electromagnetic induction.

When magnetic feild is changed uniformly around a conductor an E.M.F is used inside the conductor which produces electric current.

Electromagnetic induction is the basic principle of electric generator.

40.425m/s

Explanation:

at some point the velocity of the ball will reach 0 so we can say that Vf=0

then we have to divide the total time by 2 for upward and down ward motion of the ball which gives us 8.25s/2=4.125s

now the given are

g=9.8m/s^2

t=4.125s

Vf=0

for the formula of initial velocity

Vi=Vf-a*t

Vi=0-(4.125s)(9.8m/s^2)

Vi=40.425m/s

Because in every anniversary, they celebrate for their love for each other.
