Esra, the title of this forum is "Homework Help", not "Do My Homework for Me". Yeah, I know the answers, and this is hardly rocket science. I did my homework back when I was learning this stuff. That's why I know it to this day.
If I do it for you, what will you learn from that? Do you expect Electro Tech to always be there to carry you through the rest of school, and on the job too?
We want you to demonstrate that you are making a good faith effort to solve this.
If you get stuck we'll help.
Your next reply will probably make or break this thread.
