HI Does anyone know how to write this as product of factors. X^3+X^2-X-1. please show working. thankyou

Sorry, I think i may have not phrased the question properly. What is the difference between a negative and positive stopping voltage eg: -1 x 10^-1 and 1 x 10^-1. Also, if you multiply a negative stopping voltage, by q, the Max kinetic energy is found. But is this answer positive or...

Thanks, but I am asking about it at room temperature. Thanks

Hi, I have a few questions about the Photoelectric effect. ) If Max Kinetic energy is graphed against frequency of incident light, what does the gradient represent? 2) What does a negative stoppping potential mean? Cheers

Hi, I have a question about superconductors, especially about YBaCuO. Is this substance a conductor at a temperature above critical temp? If yes, why? Cheers

Thanks, I appreciate it. It is an equilirium reaction i forgot to put the other arrow. Appreciate you clearing my concern. Cheers

Hi, I have a question about equilbirum. 2SO2 + O2 --> 2SO3 Delta H = -99kj/MOL How does temperature, pressure and concentration affect this reaction of equilibrium. The reaction is exothermic I believe. Cheers

Just going through the problem again, I have worked how to show the answer in Part a) Thanks for your help

Thanks for your help, For Gamma I get 10, from the method you used. The last question seems to be fine. Also, for part a how would you write it out, like a maths proof or...? Thanks for your help again I appreciate it very much

Hi, I have a question, and google wasnt rather helpful, so i am posting it here. Ep = -G m1 m2 r The above formula has a negative sign. Why is this? The closer you get to Earth, does the value get bigger or smaller? Can someone please clarify this. Cheers.

Thanks- they are quite relevant!!

Hi... Even though i have extra text books and questions from school, where can I get questions for subjects like physics, chemistry, maths etc on the net for a few reasons: 1. To understand the scope that the subject can get into 2. More Practice 3. Won't get bored Cheers
