If we assume that M87* is not rotating (although it definitely IS rotating but this assumption gives us a much easier calculation that can be done quickly), what is the size of its event horizon (i. e., its Schwarzschild radius)? The Schwarzschild radius of a black hole is given by LaTeX: r_{s\:}=\frac{\:2GM}{c^2}r s = 2 G M c 2 The mass of the black hole is LaTeX: 6.5\:\times10^{9\:}\:\mathrm{M_{\od ot}}6.5 × 10 9 M ⊙, where the solar mass is LaTeX: M_{\odot}\:=\:2\:\times10^{30}\:kgM ⊙ = 2 × 10 30 k g Give your answer in AU. For reference, LaTeX: 1\:AU\:=\:1.5\:\times10^{11}\:m1 A U = 1.5 × 10 11 m and the gravitational constant is LaTeX: G\:=\:6.67\:\times10^{-11}\:\:m^{3\ :}kg^{-1}s^{-2}G = 6.67 × 10 − 11 m 3 k g − 1 s − 2 You should also read over section 2.1 in the lab script. Be careful with your units! Do not use equation 1 in the lab script; that equation uses an older estimate of the black hole's mass.

Atemperature inversion can cause a warm air mass to move over a colder air mass. this traps the colder air mass and prevents surface air from rising. this may result in which of these? a) smog b) acid rain c) freezing rain d) a thunderstorm

The path of a satellite orbiting the earth causes it to pass directly over two tracking stations a and b, which are 51 miles apart. when the satellite is on one side of the two stations, the angles of elevation at a and b are measured to be 87 degrees and 84 degrees, respectively. (a) how far is the satellite from station a? (b) how high is the satellite above the ground?
