PLEASE HELP What is the most significant change in the comet's energy as it moves from
point D to point A?
A. KE decreases, GPE decreases
B. KE increases, GPE increases
C. KE increases, GPE decreases
D. KE decreases, GPE increases

6/12=1/2

step-by-step explanation:

the entire statement is true and correct.  

there's no diagram, nothing is illustrated, and no question is asked.

truck y has a greater velocity than truck x.

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
