    Want community feedback on the CrossFire Fusion Reactor

    knew it. Old saying "too good to be true" still applies. Thank you for your time :)

    Want community feedback on the CrossFire Fusion Reactor

    I wanted to ask the community about something I ran into the other day and I know nothing about physics. I can help you build and hack your network, but stuff like this? Forget it. Other then posting this guy's website, I don't know how to explain it, beyond what he has designed, and his...

    Need calculus textbook recommendation

    The lack of orginization on the web makes me avoid it. The structure and orginization of a book is very exceptional. It teaches you without needing someone to guide you or explain things to you. Most of the math dummies books are good at breaking down problems, assisting you in solving the...

    Need calculus textbook recommendation

    I am mistaken. I thought this was a cluster of information with names of math types within catagories. CK12.org link on that website lead my to a 8 chp calculus book including youtube videos within it. That's pretty damn cool. Though I am not seeing any practicle examples in this book, i'll have...

    Need calculus textbook recommendation

    I am going to start with the dummies to calculus I, but I'd like a book that gives real life examples of calculus in use. Would that be really any math text book or does anyone have recommendations?

    Molarity to grams

    I am a beggining chemistry student and we have only had a couple lectures on stoichiometry and molarity. I will check out your site for further information.dziękuję

    Molarity to grams

    Calculate the amount(in moles) of KHP required to react completely with the NaOH in 35 mL of 0.100M NaOH. This is what I was referring to.

    Molarity to grams

    Thank you. Last question would be about converting KHP to moles. I don't understand how to make a conversion question for that.

    Molarity to grams

    thank you for the reply and groovy hair BTW. :cool: My mistake, it was the H. I had to look it over again. KHC8H4O4(aq) + NaOH --> NaKC8H4O4 +H2O(l) I looked over this a couple times and it looks balanced to me. There is ... 1 Na -> 1 Na 1 K -> 1K H+H4+H = 6 ->H4+H2= 6 C8 = C8 O4+O = 5 ->...

    Molarity to grams

    Homework Statement Calculate the mass (in grams) of KHP required to react completely with the NaOH in 35 mL of 0.100M NaOH. KHP = KHC8H4O4(aq) molar mass of "KHP"= 204.2 g/mol Homework Equations This is a double replacement reaction of the acid-base neutralization type. In other words the K...

    By how much does the speed change each second?

    A change in total position. Wonder why they couldn't say that? :redface: Guy passes a 241km marker, passes 172km marker, and hits a 148km marker. he then backtracks to the 172km marker He went the entire distance of 93km from 241km -> 148km 69km from 241km -> 172km 24km from 172km ->...

    Pre-calculus or calculus before physics?

    This is exactly my feeling after 2 weeks of this stuff. I wish it would have said this or maybe asked someone before i signed up.

    By how much does the speed change each second?

    Why must this be so hard for me. I don't understand that. I looked in my book,on the web, and not making sense of what a "resultant displacement" is. The problem to this is simple. Guy passes a 241km marker, passes 172km marker, and hits a 148km marker. he then backtracks to the 172km...

    By how much does the speed change each second?

    i have a change in speed over a change in time to equal velocity. I also have an average and instantaneous speed too. I also fixed the ^2 to the correct super script. I think that is what that is called. lol It's strange though. There is no other figures, that could be why im stuck.

    By how much does the speed change each second?

    Homework Statement A vehicle moves in a straight line with an acceleration of 3 km/h2. By how much does the speed change each second? Answer in units of km/h. Homework Equations Not sure The Attempt at a Solution sqrt 3 to get a base answer then divide by 3600 I have also...

    Basic physics requirements and a teacher

    This may be a long read. Giving you a heads up :zzz: I am trying to achieve as many opinions as possible to figure out if this problem is simply my own or the teaching style does not agree with the way I learn, maybe i simply do not belong in science. It is past the drop the course point, so...
