The atomic mass number of copper is A = 64. Assume that atoms in solid copper form a cubic crystal lattice. To envision this, imagine that you place atoms at the centers of tiny sugar cubes, then stack the little sugar cubes to form a big cube. If you dissolve the sugar, the atoms left behind are in a cubic crystal lattice. What is the smallest distance between two copper atoms?

Physics 105 Week 3 Notes By Lauren Faris Chapter 2: 1D Kinematics (Continued) The position of a particle can be described as a position vector. Average velocity is the displacement divided by the time interval. Instantaneous velocity is the instantaneous rate of change of position vector with respect to time. It is always tangent to its path. Acceleration describes...
