I think my classmate is right as well. The answers are multiple choice, so -14.4 cm is not an option unfortunately. I think my professor "borrows" his questions from other sources and sometimes he changes them slightly but forgets to change the choices of answers. Thank you all, I will have...

Homework Statement A real object is placed 9.00 cm from a converging lens that has a focal length of 24.0 cm. The image is________. My classmate answered "14.4 cm from the lens, virtual, and enlarged," but apparently this is incorrect. I solved it out and chose the option "14.4 cm from the...

Oh that makes so much sense! How simple! Thank you so much for breaking all of this down. So in a way I can look at this like two separate graphs/break it into components? And I guess the maximum values make more sense than using zero for other questions relating to this. Thanks a bunch!

Homework Statement Hello all! Basically, my professor used this graph in our lecture, but I do not really understand how to read it. The graph has three variables, so I'm guessing it is Voltage vs. Current as time increases? One question he asked was "The figure shows the voltage and...

My school requires the 23rd edition of The Manual of Mineral Science from Cornelis Klein and Barbara Dutrow. It's pretty good for mineralogy, and it's still useful for some of Petrology if you plan to take that course as well. Happy studies!

Thank you so much! I just had an epiphany and this is all way less complicated! Thank you to all who replied. And thank you so much, lewando. I wasn't taking the reciprocals of the resistances and so I was adding them incorrectly, but now it all makes much more sense. I ended up with an...

Haha, lewando, yes please! Would we consider the two 6Ω resistors parallel? And if so, the potential difference there is the same? We are getting to the point where I just smile and nod during the lecture even though I am completely lost!

1. Homework Statement [/b] So I found this problem online, and I really do not know how to go about solving it! My professor has done similar problems in class, but it's still a little confusing. A current of 1.2 A flows from A to B. Therefore, the magnitude of the potential difference...

I tried doing that, but it didn't look right when I previewed it. My browser can be kind of wonky, though, so I'll keep trying. And I've never heard of LaTeX--sounds really cool. I'll definitely google that! Thanks again for all your help!

Oh! Yay! Thank you so much,tms! I really appreciate it!

Oh, sorry, the fraction thing still is not working for me. I meant F=(k(q1q2))/(r^2)

Okay, so should I have used F=\frac{(k(q1)(q2))}(r2){}? And then I would use e as the charge of one electron (my q2) and the charge of all 94 electrons as my q1? Or am I completely off here? Thank you!

Homework Statement A particular nucleus of the element Plutonium contains 94 protons and 150 neutrons. What is the magnitude of the force from the nucleus on a single electron that is a distance of 0.563x10-12 m from the Plutonium nucleus? So basically this was a homework question that I...

Oh okay! We didn't go over this in lecture and it is not in my textbook. I'm not familiar with this formula. From what equation does one derive this? For this particular problem, would I set it up like this: 101325 Pa/8=(101325 Pa/2)e-5.5 km/H Thank you so much for your help!

Homework Statement The atmospheric pressure deceases exponentially with height. At 5.5 km, the pressure is half that at sea level. At what height is the pressure one eighth that of sea level? Homework Equations All I can think of is Pat=ρgh I know 1 atm=101325 Pa=101.325 kPa and that this is...
