- (Astronomy) Schwarzschild Radius. Part A: Find the Schwarzschild radius for the least massive black hole. Part B: Is your calculated value greater than, the same as, or smaller than the diameter of a typical neutron star and the diameter of Manhattan, New York, which is around 10.9 km?Four research teams measured the rotation period of a newly detected neutron star, and what each team wrote in its team notebook is shown in the table below. Suppose a later and more reliable measurement gives 0.250 s for the period of the same star. Decide which of the earlier measurements was the most accurate, and which was the most precise. what was written most accurate most precise team in the notebook measurement measurement A "0.20s + 30.%" В "between 0.255s and 0.265s" "0.35s" D "0.300s + 0.025s"You discover by dropping particles into it that the Event Horizon (Schwartzschild Radius) of a black hole is 171 km. How massive is it? (enter just the number in solar masses)

- What does a black hole sound like?Explain what is meant by the Schwarzschild radius of a black hole. Using a Newtonian approx- imation, derive an expression for the Schwarzschild radius, R, of a black hole of mass MBH- Calculate the Schwarzschild radius for a body with mass equal to the Sun's mass, and express your answer in units of kilometres.Gravitational forces are affected by two variable. List these two variable and indicate how they can lead to the formation of black holes. Use the word "event horizon" in your answer and indicate what it means.
