    Determination of the final temperature inside a calorimeter

    Okay, I'm working on some pchem problems and I'm stuck on this one question... A 5.33g piece of Cu metal is heated to 372.85K in boiling water, then dropped into a calorimeter containing 99.53g of water at 295.75K. The calorimeter is sealed to the outside environment, and the temperature...

    Experimental Determination of Fundamental EM Constants

    Can anyone provide a good reference (preferably on-line), or a decent description, of how the fundamental constants of electromagnetism are experimentally determined? I'm talking about constants like the permitivity and permeability of free space. I'm also curious how the unit of charge...

    MATLAB Orbit Determination Using Matlab

    I am brand new to the physics forum community, so let me start off by saying hello to everyone. I am interested I am coming up with a MATLAB code for orbit determination. I saw a thread recently discussing this type of topic but i think it was orbit determination using RA and Dec measurements...

    Orbit Determination for Dummies Another hillbilly tutorial.

    To help me in understanding this procedure, I read the fifth chapter of THE DETERMINATION OF ORBITS by A. D. Dubyago, as translated from Russian into English by the RAND Corporation. Much of the nomenclature used in this exposition is patterned after Dubyago. Initial Data. For i=1 to 3...

    Determining the Identity of an Unknown Metal Salt Containing Bromide Ion

    Nevermind, I found my mistake.. I've been trying to figure this problem out for some time now, and I can't seem to get it right: You are given an unknown hydrated metal salt containing bromide ion, MBr_2 \bullet nH_2O (M and n being variables). You dissolve 0.500g of this salt...

    Simple Determination of Initial Velocity of a Pojectile

    Simple Determination of Initial Velocity of a Projectile It is possible to roughly determine the initial velocity of a projectile shot from a launcher like the one linked to below using a number of methods. http://www.science4schools.co.uk/acatalog/10-1365.jpg Two of which I am aware...

    Antibody Heavy Chain Determination

    Dunno if anyone that reads these boards has a background with Immunology, but here goes. As far as I understand it, heavy chain isotypes can switch on any given mature B cell due to the presence of Switch regions at the 3' of any isotype gene exon. This is regulated largely by cytokines that...

    Conceptual Question in Gibbs Orbit Determination

    Hi all, hopefully someone can help me out here: I'm looking at the Gibbs' method for orbit determination, and I'm losing the conceptual picture in the vector calculations. I have no problems seeing how D and N point in the W direction (PQW coordinate system), but I'll be damned if I can...

    News Minorities right to self determination

    I'm curious what others veiws are on this. Do those who are minorities, many of which are ancient races with a long history in the middle east region (Copts, Assyrians, kurds etc.), do these people have a right to self determination? Do you think minorities that have been oppressed, slaughtered...
