In the end you will end up following the same procedure described above, which is a perfectly acceptable way to solve such problems May 27 reviewed Approve What are magnetic field lines? Apr 29 comment Optimal slit width in Young's double slit experiment How far apart were the pinholes/slits ? and what equipment did you use to make them, what kind of film etc.? Also could you post pictures, although that's not really necessary Apr 21 asked Problem in the Ladder paradox in relativity? Apr 7 comment Why can two (or more) electric field lines never cross? If I had a penny for every time this question was asked on this site (not directly, so I don't think this could be a duplicate) Mar 28 reviewed Approve Two vehicles moving in a line with different accelerations Mar 25 comment Simultaneous Charging and Discharging Capacitor You have got the concept of a capacitor horribly wrong. A capacitor in the very basic sense is two conducting plates placed parallel to and not touching each other. When you apply a potential difference across these plates, charge accumulates on them and the capacitor gets charged. Mar 24 comment How do I see things of the bright room, being in the dark room? Great 10 second video by minutephysics, related to you question: youtube.com/watch?v=VvqbjUtt3mM Mar 24 reviewed Approve How clean will first generation fusion reactors be compared to fission reactors? Mar 24 comment Free fall from space ZilbermanRafael What is happening here is that the acceleration $a$ is changing with $r$ when you go to a large height of 500km. Near the surface, this acceleration is equal to $g=-10m/s^2$ and it is approximately constant for small heights. To solve your problem what you have to do is use $GM/r^2$ as you acceleration, and then proceed with solving the differential equation in $r$ and $t$. As @garyp suggests, this requires a certain level of knowledge in calculus. Mar 24 reviewed Close Aerodynamics and thermodynamic Mar 24 comment How does a Photocell/Photoresistor work? Did you read Wikipedia? It explains the basic functioning of an LDR quite well. If you want a more detailed explanation probably about the function of CdS , specify it in the question.

I haven't checked the math, and there is a chance this is not possible. I leave that for you to determine. Mar 23 answered Where is the “event horizon” on a basketball hoop?
