Three particles are placed in the xy plane. A 50-g particle is located at (3, 4) m, and a 40-g particle is positioned at ( 2, 6) m. Where must a 20-g particle be placed so that the center of mass of this three-particle system is located at (3, -6)?

cell differentiation  is how generic embryonic  cells  become specialized  cells. this occurs  through a process called gene expression. gene expression is the specific combination of genes that are turned on or off (expressed or repressed), and this is what dictates how a  cell  functions.
