university of california Operations And Supply Chain Management Assignment Help - Tidal Forces

Question - Tidal Forces near a Black Hole. An astronaut inside a spacecraft, which protects her from harmful
radiation, is orbiting a black hole at a distance of 120 k/n from its center. The black hole is 5.00 times
the mass of the sun and has a Schwarzschild radius of 15.0 kin. The astronaut is positioned inside the
spaceship such that one of her O.03O-kg ears is 6.0 cm farther from the black hole than the center of
mass of the spacecraft and the other ear is 6.0 cm closer.
(a) What is the tension between her ears? W ould the astronaut find it difficult to keep from being tom
apart by the gravitational forces? (Since her whole body orbits with the same angular velocity, one ear
is moving too slowly for the radius of its orbit and the other is ...Read More moving too fast. Hence her head must
exert forces on her ears to keep them in their orbits.)
(b) Is the center of gravity of her head at the same point as the center of mass? Explain. ...Read Less
