Wow nvm, i answered it 1.26 cents instead of 126 cents..-.- thanks anyways

Homework Statement What does it cost in cents to leave a 1800 Watt electric oven on for 7 hours? Assume that you pay 10 cents for every kilowatt hour which you use.Homework Equations Well i don't know if I am supposed to use P=E/t. i don't know how I am supposed to use it The Attempt at a...

I don't have much of a homework problem that i need help with, but the homework requires us to use a equation ... P = E / t there is a little triangle before the E i don't know what it means Thanks for help

nvm, i believe it is the opposite of what i said above.

It is not a homework problem, thought it can kinda be. But when they show you a diagram with object A and B, If the electric field point towards A and away from B. Does that mean that A is + and B is -?

Yes i got it..thanks lol

oh ok..let me try that..ive tried plugging in over and over..but couldn't get the answer..

how do i get values of k, q1, and q2 in units of Coulomb? oh wait they give it to us in C

but the thing is i don't know where to start..

Homework Statement I have physics homework and i don't quite seem to understand the question: Two objects ( X and Y ) are placed at a distance of .800m from each other. The charge on X is 6.65000x10^-6 C and Y is 7.73000x10^-6. What is the value of electrical force (in Newtons) between the two...
