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 Γ 10 9 M β, where the solar mass is LaTeX: M_{\odot}\:=\:2\:\times10^{30}\:kgM β = 2 Γ 10 30 k g Give your answer in AU. For reference, LaTeX: 1\:AU\:=\:1.5\:\times10^{11}\:m1 A U = 1.5 Γ 10 11 m and the gravitational constant is LaTeX: G\:=\:6.67\:\times10^{-11}\:\:m^{3\ :}kg^{-1}s^{-2}G = 6.67 Γ 10 β 11 m 3 k g β 1 s β 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.

The focal length of a relaxed human eye is approximately 1.7 cm. when we focus our eyes on a close up object, we can change the refractive power of the eye by about 16 diopters. (a) does the refractive power of our eyes increase or decrease by 16 diopters when we focus closely? explain. (b) calculate the focal length of the eye when we focus closely.
