i said sunlight is missing the energy of hydrogen since it uses it, hence when passed through a prism the spectrum of hydrogen will not be seeni dont think its totally right tho :?
For hydrogen question:* Hydrogen is in space between Sun and Earth.* As light passes through them some wavelengths corresponding to difference in energy levels are absorbed.* Hence the other wavelengths are passed through.* Note resemblance between emission spectrum of hydrogen and absorption.Something on the lines of that, I wrote more.. but can't remember.
Yeah, so I got something like (can't remember very well):2.5 A, 10 V, 2 V6 W, 5 W, 5 W
i got 1.1 for the one we had to read from the graph, that should be right, yeh?? :?
Ahmad, your answers look similar to mine. (but im not certain) i remember considering a voltage drop in my power line question.Vdrop was like 4 *.5 = 2 V drop across the power lines wasn't it?
