A dog is being slowly pulled by his dog chain across the ground at a constant speed. What forces are being applied:a. force frictionb. force due to gravityc. magnetic forced. normal forcee. spring forcef. tensiong. applied forcethere can be more than one answer.
well theirs force of gravity, that's a given. then normal force because the dog is on a surface. force of tension in the dog chain(dog being pulled and the one pulling the chain,they re in opposite direction). applied force for the effort of the person/thing pulling the dog. but your question is really vague, it really depends how the dog is being pulled. if the dog was being dragged or if the dog was walking or who/what was pulling the dog.
Possibly all.no problem justifying all but (c) (e) c) It depends on the material of the dog chain, if magnetic material it would feel a magnet pull of the earth's magnetic field. e) this is really stretching it :) but perhaps the dog chain has a spring on it or the material of the chain is such that there is a little elastic give back once the tension (force) pulling on it is released.
