Problem in geometrical optics This might be more fitting for Math.SE, given that the problem is simply asking about mathematical manipulations rather than the physics behind them. |

Semi-major axis and ellipticity of a binary system? What specific parts were confusing? I hope to be more clear next time. |

How to find Electrostatic Potential Difference? Yeah, you'd want the total E. |

Does the sun rotate? @Dan You say that we can use the spectrum of light from a hot body to determine rotation. It is probably my lack of astronomy knowledge speaking, but how would one do that? |

Does the sun rotate? Out of curiosity, do modern telescopes have the resolving power to find the individual doppler shifts of the various parts of faraway stars? |

Calculating the amount of heat energy radiated by sun You say you "tried some stefan method" - what specifically did you try? Can you provide us with some of your work? |

Inelastic collision and impulse You need to consider the center of mass of the entire system, not just the car. In your example with the fist, the fist has a certain mass, and when it is moving down before hitting the car, it makes the entire center of mass of the system move downwards. As the fist hits, the fist is slowing down, making the entire center of mass's downward velocity decrease. |

Very large absorption lines in stellar spectrum Thanks for the link. Out of curiosity, what makes the TiO bands so wide compared to simple atomic lines? |
