desis Posted November 12, 2008 Posted November 12, 2008 AN oxygen atom is four times as massive as a helium atom. In an expriment of helium atom and an oxygen atom have the same kinetic energy. WHat is ratio V(He)/V(o) of their speed?
Sayonara Posted November 13, 2008 Posted November 13, 2008 Think about what the terms are, and how they are related. What does "massive" mean? What is kinetic energy? How do these relate to a body's speed?
