Homework Help: A metal rod and a metal ball more submerged in H2O

  1. Aug 7, 2011 #1
    A metal rod and a metal ball more submerged in h2o, such that one end of the rod is adjacent to the ball. if the h2o will be heated from 30 k to 65 k, what is the acceleration of the ball? the initial length of the rod is 6 m.

    Vball= 6 cm3
    Vrod= 9 cm3
    Crod= 13 cal/g.c degrees
    Cball= 8 cal/g.c degrees
    Ch2o= 1.0 cal/g.c degrees
    Mball= 60 g
    Mrod= 607 g
    α= 0.005/c degrees

    Topic is about Hydrostatic

    I was absent during the assigning of this homework. I really need help! Thank you! :)
