    Does the force of gravity alone provide the means for the centripetal force, is this why they are equal ? For explaining why there is no normal force, could you see it as the astronaut having the same acceleration as the ship and so the relative acceleration = 0, so it's under the illusion almost of having no acceleration so there's no force ? Please !! If you have different reasoning please share. I'm just trying to wrap my head...

    D. Since the proton is moving while feeling a force, work is done on the proton: Won P = Felec Mlax Icoso, where lax is the magnitude of the proton's displacement and is the angle between the direction of that displacement straight to the left in this case) and the direction of the force on the proton. While the proton is approaching the nucleus the work done on it is positive, negative, zero). Important: our attention is now focused on...

    Please read the article and answer about questions. You and the Law Business and law are inseparable. For B-Money, the two predictably merged when he was negotiat- ing a deal for his tracks. At other times, the merger is unpredictable, like when your business faces an unexpected auto accident, product recall, or government regulation change. In either type of situation, when business owners know the law, they can better protect themselves and sometimes even avoid the problems completely. This chapter...
