Suppose that you cut a sugar cube into smaller and smaller parts. If you could separate out one molecule, which of these describes what you have?
A. a carbon atom.
B. a molecule without atoms.
C. a molecule with no mass.
D. a molecule of sugar.

the answer is b

explanation:

the rearrangement of particles in a physical change. hope this

0.93xc=0.93x3x10^8m/s

2.54cm is 1 inch

360seconds i 1 hr

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
