If you slowly increase the strength of an electric current flowing through the wire, you would expect the magnet to become stronger. The correct option among all the options that are given in the question is the first option or option "a". The magnetic field around the wire becomes stronger. I hope it helps you.
Simplify the expression.
2x^3-10x^2+22x-14
6x = 15
I apologize if this is wrong!
The rule is that: You are adding 5 each time
5(100) + 4 = 504
Your answer should be 504
hope this helps
