I heard about this, nanocar

  1. Oct 26, 2005 #1
    is It real?.. Physicists made a nanocar, out of a single molecule..

    on about.com they have an article, but i doubt it's reliable.

    and while your at it, explain this to me :confused: :confused: :confused:
    I need some help, understanding and solving this problem.

    When you mix hot and cold liquids you can find the temperature of the mixture by using the formula T= ah+bc divided by a+b, where T is the temperature of the mixture, h is the temperature of the hot liquid, c is the temperature of the cold liquid, a and b respresent the amounts of hot and cold liquids. Suppose you mix hot tea and cold milk in a ratio a:b of 9:1 and find that the temperature of the mixture is 117degrees You then change the trea:milk ratio to 2:1 and the temperature drops 96degrees. Find the initial temperatures of the tea and Milk.

    Having us answer your homework questions is not allowed.

    As for the nanocar I'd have to look that up...
