Aphotographer uses his camera, whose lens has a 70 {\rm \; mm} focal length, to focus on an object 5.0 {\rm \; m} away. he then wants to take a picture of an object that is 50 {\rm \; cm} away. part a in which direction must the lens move to focus on this second object? in which direction must the lens move to focus on this second object? toward the film away from the film request answer part b how far must the lens move to focus on this second object? express your answer to two significant figures and include the appropriate units.

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.

explanation:

the answer is b

explanation:

the answer would be 32*f

electrical potential energy =0.072 j

explanation:

electrical potential energy is given by

u= q δv

q= charge=6 c

δv= potential difference and is given by

δv= e d

e= electric field

d= distance=5 mm=0.005 m

δv=2.4 (0.005)=0.012 v

now electric potential energy= u= q δv

u=6 (0.012)

u=0.072 j
