This is not an assignment problem, but I am studying for my quantum mechanics final exam and came across a derivation in the book which I can't seem to get my head around :( The example in the book is solving for the probabilities of getting +h(bar)/2 and -h(bar)/2 if we are to measure the...

Homework Statement We are given a peak-to-peak voltage of 10. I am attempting to explain the following characteristics: 1) With a larger forward bias (and a corresponding smaller reverse bias), the storage time increases. 2) With higher frequency, the storage time decreases...

I see... Thanks for the clarification!

Thanks for the prompt reply! I did some further research and found that the % ionization of a weak acid/base increases as its initial concentration decreases (becomes more dilute). I guess this conclusion for strong acids follows the trend of the weak. But why can't pure acid not be...

I solved an assignment problem and I came to the conclusion that the % ionization of a strong acid decreases as the initial concentration of the ionized acid is increased. I don't fully understand why this is..? Any clarification would be greatly appreciated! Thanks in advance!

hmm... interesting... thanks for the ideas! we'll try them out =) ... but it's going to be hard to achieve direction and airtime accuracy :\ and no, we cannot provide any launch force (that includes throwing or slinging...)

hi... I am a group member of !Live_4Ever! 's science project. In response to your question, we are not allowed any wings/fins etc... we must use totally ballistic flight characteristics. It's quite a headache because what can glide without the use of fins/wings? In addition, there is no...

please confirm these diagrams of me! i understand that the critical angle of a specific glass prism may not be exactly 45*... but i know it will be similar to that. also, i understand that refraction will occur at incident angles less than 45*... but reflection also occurs as well...

oh rite.. snell's law... ok, thanks.

i understand that when a ray of light enters a non-hypotenuse side of a right-angle prism at the perpendicular angle (90*) , it is reflected off the interior of the hypotenuse at a 90* angle, exiting out the other non-hypotenuse side how would light travel through a right angle prism if: the...

hmm... i read your advice but i don't really understand what you mean... i tried drawing a finder-ray diagram to illustrate the vertical flipping of the image but i did not manage to attain an asnwer as to why the image is vertically flipped. the finder-ray diagram only showed the side of the...

I have successfully constructed a prismatic telescope with a fairly sharp, erect image. However, I was disappointed to discover that the image was vertically flipped! That is, in real life, there would be a car on the left and a man on the right. When looking through the telescope, the...

hi! i kinda grasp the concept of atmospheric pressure and how it affects everyday stuff... but I'm stuck with this one problem that i can't seem to understand. The experiment involves filling a cup with water. Then, a cardboard piece is placed completely over the opening of the cup and...

How does light travel in a vacuum?? it is understood that light travels through a medium by interacting with the atoms within that medium but in a vacuum, there are no atoms which, as a result, can't accommodate this interaction, yet light can still travel through...how? it has also been...
