Apositively charged object is placed to the left of a negatively charged object. which best describes how the positively charged object will move?
to the left, in the direction of the electric field lines
to the right, in the direction of the electric field lines
up in the direction that the field lines bend away
down in the direction that the field lines bend away

In the electric field lines go from source or positively charged object towards negatively charged object. .

If positively charged object is placed to the left of negatively charged object then it will move towards it from the right.

So the answer is: to the right, in the direction of electric field lines

a) electrical > light, sound, and thermal< < < <

) the mechanical energy of the firefighter moving.< < < < a) electrical > light, sound, and thermal< < < <

c) both a and b.
