The particles are released from rest simultaneously. They repel one another, and start moving apart. After a long time, when the particles are far apart, essentially all of the initial electric potential energy has been converted into kinetic energy, some taken away by particle 1 and the rest by particle 2. What percent of the initial energy does particle 2 end up carrying away

adding a(n) to an electric circuit would increase the magnetic field around a wire;

b. solenoid

a solenoid is a type of electromagnet whose purpose is to generate a controlled magnetic field.

if the purpose of the solenoid is instead to impede changes in the electric current, a solenoid can be more specifically classified as an inductor rather than an electromagnet.

the total distance that martina travels that day is

(distance from home to mom's office) plus (distance from mom's office to school)

plus (distance from school to library) plus (distance from library to friend's house)

plus (distance from friend's house to martina's house).

(we don't know what any of these distance actually is.)
