Homework Statement objects A and b are submerged at a depth of 1m in a liquid with a specific gravity of 0.877. Given that the density of object B is one third that of Object A and that the gauge pressure of object A is 3atm, what is the gauge pressure of object B? assume atmospheric pressure...

or, why was one never adopted?

thats the exact problem that I am constantly wondering about.. I am using this for b2b cold calling , (or b2b "warm' calling as i like to call it) --a latency issue would be irritating as f*** and actually would ruin every call. I am now thinking of just going with my cell carrier , they would...

I m hoping someone on here has small biz and knows about the best 800 number or 866 or whatever it is now. I thought landlines were extinct now? so if they are, who sells 800 numbers and how do you get one? i want one that I can just route to my phone, receive and make calls with it, but I don't...

yup that happened to me too... there must be some set rule for this though, but it seems to vary from book to book (unless its based on how you click within the book?) I already looked around for an answer on google forums but can't find answer btw..

How many pages can you read for free on a book that's on googlebooks? I mean how do they determine this, is it like a certain percentage of the book, then you have to buy it? How does it work? thanks

I mean there's one way to read a book where the author becomes all important to the narrative, (like his/her life, why it was written, the era it comes from, etc) ) and then the other way is where what the author writes has a life of its own, and takes on meanings that the author might not even...

I looked on the wiki math symbol page and couldn't find one, so I am thinking "corresponds" is wrong word. Is it supposed to be equals sign with hat on it? for example, "energy directly corresponds to wavenumber" thanks for any help

Book says one of the properties of EM waves is they can impart momentum (and angular momentum)... What would be an example of this? (a simple example in terms of first year physics i mean)

Homework Statement its not a homework question but I didn't know where else to ask. I want to know how we know which salt to use for salt bridge. I think I understand what we don't want the salt bridge to do --we don't want it to react, and that its function is to neutralize the solution so...

I thought it would be polyfurcation but it s not in dictionary. Also if blood vessels use venturi effect to lower pressure in some places, what is the extra speed used for?

Well i guess my all time fav soundtrack is Inception. Its actually the reason I got all interested in soundtrack questions.. I don't know technicals of music but I've never heard music like that before. The chords sound really menacing and almost scary lol.. The music sounds deadly serious to...

thats exactly what I've been thinking for a number of questions actually.. the grammar is messing up the questions so i think it must be translated .. but its on Khan academy , kinda surprised me because I thought Khan is a pretty serious site now..

When they release soundtrack do they pt the song order so it fits together as one connected composition or is it just like the movie sequence? Hans Zimmer Inception for example, does it follow some musical structure or is it exactly as youd hear it in the film?

Homework Statement One of the hints to this problem says "An object in motion always gains kinetic energy, so the change in energy of an object starting from rest would be P = m(v^2) / (2t) I understand that a moving object has kinetic energy, but why did they say it gains kinetic energy (or...
