C. is a change in force.
D. does not depend on the applied force.

it is very well related to a lot of things but with my limited knowledge i can confidently say that the answer is space.

i think they are all correct

explanation:

they seem good

i believe the answer would be:

d. violin, clarinet, french horn, and tuba

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
