Using Coulomb's law, rank the particle interactions from most attractive to most repulsive. Question 18 options: a particle with a 1– charge separated from a particle with a 2+ charge by 150 pm. a particle with a 1– charge separated from a particle with a 3- charge by 150 pm. a particle with a 1– charge separated from a particle with a 2- charge by 150 pm. a particle with a 1– charge separated from a particle with a 3+ charge by 150 pm.

Two students, each riding bicycles, start from the same apartment building and ride to the same building on campus, but each takes a different route. the first student rides 1100 m due east and then turns due north and travels another 1430 m before arriving at the destination. the second student heads due north for 1930 m and then turns and heads directly toward the destination.at the turning point, how far is the second student from the destination?
