Auniform thin rod of mass =3.47 kgm=3.47 kg pivots about an axis through its center and perpendicular to its length. two small bodies, each of mass m=0.263 kgm=0.263 kg , are attached to the ends of the rod. what must the length of the rod be so that the moment of inertia of the three-body system with respect to the described axis is =0.907 kg·m2i=0.907 kg·m2 ?

Neptune is the eighth planet from the sun. it was the first planet to get its existence predicted by  mathematical calculations  before it was actually seen through a telescope on sept. 23, 1846. irregularities in the orbit of  uranus  led french astronomer alexis bouvard to suggest that the gravitational pull from another celestial body might be responsible. german astronomer johann galle then relied on subsequent calculations to   spot neptune via telescope. previously, astronomer galileo galilei sketched the planet, but he mistook it for a star due to its slow motion. in accordance with all the other planets seen in the sky, this new world was given a name from greek and roman mythology — neptune, the roman god of the sea.
