Hey, I'm adult but going to university for the first time, and I am taking Physics. My first semester is all about Math. Algebra and Analysis.
I'm usually pretty good at math, but right now, we are "laying the foundation" for calculus, and of course all these things we took for granted...
hmm, I'm still a little confused. Here's an example straight out of my book.
"Calculate the energy released when three Helium-4 nuclei combine to form a carbon-12 nucleus"
Book example follows the principle (mi-mf)
or: (3*4.002603u - 12u) = 0.007809u
However, when it is explaining the...
I'm taking high school physics, and I've had problems in the past with flat out errors in my textbook (I've brought them up here). It's incredibly frustrating when your trying to understand something.
Anyways, I need to know which is right:
The text in my book goes through to explain...
So I'm getting confused by my textbook, and having problems finding any straight forward answers online. I am studying Gr.12 physics myself, so I don't have a teacher. I understand the nature of charges, but somehow I'm getting mixed up when dealing with non-conductive materials. Basically, I...
Awesome, well, thanks. I know it's hard for them to be 100% correct but man is it frustrating when the book is wrong and you question your basic understanding for hours.
Yeah, It's definitely a negative charge. It's blue and it's got a (-) symbol inside.
It's frustrating because It's as if my understanding is a house of cards just ready to topple over.
I can understand how the field would be stronger in between point A and the source, vs point B and the...
Hey everyone, so I think my question will be relatively simple compared to what I've viewed elsewhere here. Basically, I am an adult taking grade 12 physics as self study, and for the most part I can work things out ok. I am planning on taking the diploma exam for my province in January...
