Agneisse Posted May 24, 2008 Report Share Posted May 24, 2008 (edited) C[sub]s[/sub] = Q/AΔT Can someone explain to me what the above formula (from Topic 8 of the Physics data booklet of 2009 and beyond) means? I take A to mean area and ΔT to mean the time passed, but can't really sort out Q and Cs in my head. Also, when calculating the area of a solar panel in radiation terms, my teacher said that the net area is multiplied by the cosine of the angle that the panel is placed at to find the "effective" area of the solar panel. Why is it necessary to multiply the area with the cosine of the angle? Last thing - are there any more solar power-related formulae that I should know about? Thanks (: Edited May 24, 2008 by Agneisse Reply Link to post Share on other sites More sharing options...
babakren Posted May 24, 2008 Report Share Posted May 24, 2008 (edited) I think this one is the new topic that i just finished.. Cs is the surface heat capacity which is measured in Jm[sup]-2[/sup]K[sup]-1[/sup] so it's the energy required to raise the temperature of unit area of a planet's surface by one degree you could actually find a decent explanation and more formula's about the topic from the IB Study Guide book by Tim Kirk Edited May 24, 2008 by babakren Reply Link to post Share on other sites More sharing options...
Agneisse Posted May 28, 2008 Author Report Share Posted May 28, 2008 Yeah I would use a book but I don't have one (it's a research project). Thanks anyway (: Reply Link to post Share on other sites More sharing options...
