hey! i need some help with a triple integration problem using spherical coordinates. it's the volume of a small part of a sphere. rho from 5 to 6, phi from pi/6 to pi/4 and theta from pi/4 to pi/3.
i got an answer of (-91/72) x pi x (sqrt(2)-sqrt(3))...am i right? Thanks!
I don't mean to imply that any of you are stupid or anything, but I don't think my question was fully understood...
When you say you mess up plenty of things when doing it for the first time, do you mean mistakes that are 'fatal' to computer hardware? Perhaps my question was not clear...
I understand that it must be easy to learn and I can see why it is straight-forward. But assuming that my friend never did it before, has no manual and has no one there to help him, what are the chances that he will mess up? What if he simply does not understand the concept of grounding? In...
Greetings, its the noob again:)
Recently I had a discussion with a friend of mine who claimed that he knew how to set up his own computer (putting the parts together, not making the parts themselves). When I asked him if he's ever done it, he said no, but he said that he knows what most of...
This is such a noob question, but why is willib's diagram grounded? I can see why cosmik's diagram is ground (to complete the circuit), but why does a circuit connected from - to + on the battery need to be grounded?
Hello everyone:)
I have questions regarding the "memory effect" and voltage depression.
1.) Could someone explain to me in layman's terms exactly what they are? I don't quite understand the explanation on wikipedia.org.
2.) Additionally, my friend told me that when you turn your mp3...
Hey rbj, thanks:)
I understand your analogy to a certain extent. What I would really like to know is the nature of that wave you are talking about. Why does it exist? Was my analogy of the waves of the ocean a correct conceptualization?
Actually i was thinking more of a handgun. The reason this whole thing came up is complicated, but in short I was watching a movie where a woman was jumping sideways with quite a large gun loaded with a large bullet (Chronicles of Riddick, stupid movie...I know). When she fired, she did not...
Since I'm no expert in this field, I simply defined recoil as the push that the shooter feels. Simply put, my question was would the shooter feel a harder push in a situation with a gun and bullet size increased in proportion?
