Astudent analyzes data of the motion of a planet as it orbits a star that is in deep space. the orbit of the planet is considered to be stable and does not change over time. the student claims, "the only experimentally measurable external force exerted on the planet is the force due to gravity from the star." is the student’s claim supported by the evidence? what reasoning either supports or contradicts the student’s claim? yes. other external forces are exerted on the planet, but they are of negligible magnitude.
