Answer:
Part a)
Rate of charge flow is known as electric current
Part b)
Average current flow is

Part c)
As we know that current density is current per unit area

Explanation:
As we know that angular frequency of rotation is

now by basic definition of electric current
Part a)
Rate of charge flow is known as electric current

so here we have


Part b)
here we know that



now we have


Part c)
As we know that current density is current per unit area
So we have
