Amass, m , and spring, k, are at rest in a gravity field, about to be struck by a mass, m, falling from a height, h. the mass, m, sticks to m , and the two move downward. the variable, x, keeps track of the displacement after impact. sketch the general motion of x for some period of time after impact. how many equations do you think are needed to describe this system mathematically? if the system ever came to rest, what would be the deflection of the spring?

i am not soo sure about this one but there are 4 mathematically

explanation:

0.3x0.21x0.08kg=mass 1 sheet

mass 500 = 500xmass 1

volume pile = 0.3x0.2x0.048

density=mass/volume= 500xmass 1/0.3x0.2x0.048

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.
