Oh wow! Thank you so much.

I am trying to answer the following question: A cyclist starts from rest and pedals such that the wheels of the bike have a constant angular acceleration. After 12.0 s, the wheels have made 26 revolutions. What is the angular acceleration of the wheels? My attempt at a solution: This...

Haha. Yea I was starting to think that that was a prerequisite...

Hobbies? I don't mean to be rude, but the last thing I was thinking about when I was a preteen was my future plans of studying engineering and including mathematics in my hobbies. Anyways, I did a quick review of the concepts and I understand how to answer the question; and wouldn't you...

I have learned long division however, the same day I learned it was also the last time I've ever used it. The problem is that I learned long division when I was in elementary school; little did I know that nearly 20 years later I would be studying engineering calculus. Long division is not a...

Things have changed old man. You are hardly a PF contributor! Its pretty pathetic when a "homework helper" insults the very person who is asking for help. Please do me a favor and never respond to any of my posts!

The question is "without a calculator, long divide 425/836. Round to the nearest hundredth. Estimate your answer before starting." My attemp at a solution: Well, my estimate would be approximately one half, since 400 divided by 800 would be 0.5; however, I'm not sure how to long divide a...

Huh?

Hey, I just got out of my lab at school and just realized that me and my professor made a mistake. He marked my lab complete, and I also thought it was complete, however, I just realized that there was something missing. The problem is that I can't go back into the lab to try it out again...

I am 22 years old, and I am about to begin studying Environmental Engineering at Dalhousie University. I have some previous academic work; I have graduated from an Electronics Engineering program from a local college, and I have also graduated with honours from another college in a...

I'm doing a lab on electrostatics, and I need to develop an electrostatic series. I've established a small sheet of plastic (20") as my reference material for determining charges. In my lab, it was given, that rubbing plastic in wool would give the plastic a negative charge meaning it is...

I understand what you're saying, and I should state, that in my lab, it is given that polymers rubbed in wool will acquire a negative charge; thus my reference material. However, what I'm confused about is the fact that I rubbed plastic wrap in wool, and because plastic wrap is more...

I'm doing an electrostatics lab and I'm getting a bit confused. The object of the lab is to establish an electrostatic series. First, I must choose a reference material, like plastic wrap. Then I charge this reference material by rubbing it in wool. Now, just by looking at any other...

Awesome! Thanks so much, I'll look that up.

Hey. I'm just doing a lab an electrostatics and my coursebook suggests a number of materials to use, however, I'm not really getting clear reactions with them. The purpose of the lab is to create an electrostatic series. I first have to establish a reference material; I chose cellophane or...
