Yes, the problem is given in Coulombs/second. However, it is another two chapters before we have any introduction to Faraday's Constant, so I don't understand how that, charge per mole of electrons, would fit in here. This is my thinking so far and I have no clue if it's correct. 1: I find...

Homework Statement When light of wavelength 630 nm is directed onto a photocell, electrons are emitted at a rate of 2.6 *10 raised -12 C/s. Assume that each photon that impinges on the photocell emits one electron. How many photons per second are striking the photocell? How much energy per...

Well my first attempts at using the editor aren't so good. I'm going to go take the laundry out of the dryer and sit and play with your answer for a While to make sure I know what's going on. And the reason you inverted the integral is because it went from a higher number to a lower one, right?

( \int {cos^t dt}) *(\int{ e^t^2 dt) } . I am trying out the text editor I just found on the site to see if I can more clearly write oute the problem. So I'll post to see if this comes out ok

I apologize for being so dense, but how does that apply to the stated answer for the quiz of cos^5(x) * integral with e + integral with cos^5(t) * (-2x)e^x^4 it's the answer for the last of the four terms in the result that's throwing me. To me, it seems the derivative of the integral of e^t^2...

Homework Statement Find f'(x) for (integral from 0 to x of cos^5(t)dt)* (integral from x^2 to 1 of e^t^2 dt). No differentiation allowed in the answer Homework Equations The Attempt at a Solution. I used the product rule and integrated then differentiated the first term --> cos^5x*...
