In a thevenin equivalent circuit are you able to find the power used in the circuit by the variable load? I have a circuit where the variable load is in parrallel I was thinking the power used in the original circuit by the variable load would be different than in the equivalent because it is...

to do it on your casio classpad you can use the stats program. click on the calc dropdown, all the way at the bottom is distribution, click on that then you want to use normal CD, click next and use your lower value as -infinity then you should be able to figure the rest.

Ever heard of latent heat? try finding an equation to do with this

you never know the book might spell it that way to?!??

the only thing i changed from the book is that it says a light rather than a sign.. but i think it may be a book error to. This book has many errors

Homework Statement a uniform 2kg horizontal beam is 50cm long is bolted to a wall and supports a 5kg sign. calculate the tourqe produced by the combined weight of the beam and the sign about where it is mounted to the wall. Homework Equations tourqe = F x Perpendicular distance The...

Ah that makes it a lot easyer, i totally forgot about when the denominator is imaginary that you multiply both numerator and denomiator by the conjugate. Thanks alot!

Homework Statement i am supposed to prove that for the complex number z=cis\theta the conjugate is \frac{1}{\overline{z}} Homework Equations if z=a+bi \overline{z}=a-bi The Attempt at a Solution all that i can think of is that \frac{1}{cos\theta i sin \theta} =(cos \theta i sin...

hmm yeah i think i may have answered my own question since it is at the top of the loop now we add weight force to the centripetal force which is in turn 4mg so it would be 5mg then??

What if you had to find the force at the top of the loop would you use 6mg+(mv^2/r)?? because the weight force is acting downwards now?? Sorry Sirsh its everyones question now!

Ok cool i see this happens molybdenum. Also what would happen to phsical properties? ultra hard? Ultra unreactive?

Hmm so can actually happen just not with carbon, i get why now because of its tetrahedral shape. Also is there any special names for these substances, as well as would you know what the most amount of bonds there are possible?

I am wandering whether this can happen? When a molecule shares 4 pairs of bonded electons? Say like a C2 Molecule?? maybe. Could it happen or does it happen??

okay i was finally able to prove it! \int\sqrt{a^2-x^2} dx =\int a^2-a^2sin^2\Theta acos\Theta d\Theta =\int\sqrt{a^2(1-sin^2\Theta} acos\Theta d\Theta =\int\sqrt{a^2cos^2\Theta} acos\Theta d\Theta =\int a^2cos^2\Theta d\Theta =\frac{a^2}{2}(\Theta+sin\Thetacos\Theta) i know...

ok so if i do... \int\sqrt{9-9sin^2\Theta} =\int3-3sin\Theta =3\Theta+3cos\Theta is it going in the right direction now?? thanks for the help
