Agolfer, driving a golf ball off the tee, gives the ball a velocity of 38 m/sec. the mass of the ball is 0.045 kg, and the duration of the impact with the golf club is 0.003 sec. what is the change in momentum of the ball?

Explanation:

momentum (p) = mass × velocity.

Change in momentum (∆p) = final momentum - initial momentum.

∆p = 0.045×38 - 0.045×0

∆p = 1.7 kg m/s.

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.
