Answer:
It's B, anything about a circle is Stationary
Answer:
The current would be same in both situation.
Explanation:
Given that,
Current I = 13 A
Number of turns = 23
We need to calculate the induced emf
Using formula of induced emf is

For N = 1

We need to calculate the current
Using formula of current

Put the value of emf

Now, if the number of turn is 22 , then induced emf would be

Then the current would be




Hence, The current would be same in both situation.
hi, so the material that would normally form mineral crystals does not have time to form a crystalline structure because of very rapid cooling after volcanically erupting into the air or onto the surface. Obsidian is a volcanic glass.
