- 4. Black holes are theorized to form from (HS-ESS1-3) a. very massive planets that collide with very large stars, resulting in an excessive amount of matter This matter collapses onto itself, extinguishing the star and resulting in the black hole b. very massive stars when their core nuclear fuel has essentially expired, resulting in the core collapsing in on itself. This is due to gravitational forces that act without nuclear fusion counteracting them C. very small stars when their outer shell nuclear fuel expires, leaving the dense core to collapse in on itself. This results in massive gravitational forces d. very young stars that do not have enough nuclear fuel to start the massive chain reactions normally produced in stars emitting large amounts of electromagnetic energy 5. What evidence helps supports the idea of the Big Bang Thoery (HS-ESS1-2) a. Earth Soil Samples b. Neil DeGrass Tyson c. Apparent motion of planets d. Red shift of distant lightWhat would happen to the orbit of the Earth if the Sun were suddenly replaced with a black hole the same mass? A) The Earth would be sucked into the black hole B) The orbit of the Earth would remain unchanged C) The Earth would become a black hole D) The Earth would fly away into space(Astronomy) Black Hole Gravity I. If the gravitational acceleration is g=GM/r^2, what gravitational acceleration does a particle feel at the Schwarzshild radius of a 12-solar-mass black hole star? Express your answer in units of m/s2. Please round your answer to three significant digits.
- (Astronomy) Black Hole Gravity II. If a person was falling feet first into a 10-solar-mass black hole and his feet were at the Schwarzschild radius, what is the gravitational acceleration at his head? Assume the person is 2 m tall. Express your answer in units of m/s2. Assume gravitational acceleration is g=GM/r^2What will be the Schwarzschild radius of Earth?
