1)
Astronauts orbiting the earth in the space shuttle experience a force of gravity that is
several times greater than the Fgrav experienced on Earth's surface.
several times smaller than the Fgrav experienced on Earth's surface.
a fraction greater than the Fgrav experienced on Earth's surface.
a fraction smaller than the Fgrav experienced on Earth's surface .
... nonsense! Orbiting astronauts do not experience any gravitational pull from the earth.

The supermassive black hole at the center of a galaxy has a mass of 6.5 billion solar masses. If we assume that it is a Schwarzschild black hole, what is the radius of this black hole?
A. 18 light hours
B. 20 light hours
C. 16 light hours
D. 14 light hours
Is the answer A?
S. radius = 3 x 6.5 x 109 x 9.26567-10 = 18.1 light hours
Thanks!
Astronomers now think that there is a black hole with more than 4 milliion times the mass of our Sun at the center of our galaxy?
Roughly how large would the event horizon of such a supermassive black hole be?
a. the size of our moon
b. about 4 light years across
c. about 17 times the size of our sun
d. about the size of an atom (so much mass really compresses the event horizon)
e. this question can't be answered without knowing what kind of stars were swallowed by the black hole

- I am trying to calculate the gravitational mass (in solar masses) I have the formula M= V^2 R / G (4.31 x 10^-6) The paperwork says our numbers should be big but I am coming up with .002 etc. What am I doing wrong?arrow_forwardWhich statement concerning black hole masses and Schwarzschild radii is not true? A. Even an object as small as you could become a black hole if there were some way to compress you to a size smaller than your Schwarzschild radius. B. The more massive the black hole, the larger the Schwarzschild radius. C. For black holes produced in massive star supernovae, Schwarzschild radii are typically a few to a few tens of kilometers. D. In a binary system with a black hole, the Schwarzschild radius depends on the distance from the black hole to the companion star.arrow_forward1.2 1.0 0.8 0.6 Cosmic background data from COBE 0.4 0.2 0.0 0.5 10 Wavelength A in mm c) Background (CMB) undertaken by the COBE satellite.

- Hubble's First Attempt. Edwin Hubble's first attempt to measure the universe's expansion rate was flawed because the standard candles he was using were not properly calibrated. Look at (Figure 1) a.Estimate the value of Ho corresponding to the solid line in the figure.

Express your answer in years to one significant figure.arrow_forwardPart 1. Stellar Mass Black Holes These are the collapsed cores of massive stars which end their life in supernova explosions. The stellar core can no longer use nuclear fusion to hold up the immense gravity, and collapses until its escape velocity rises higher than the speed of light. Voila! A black hole is formed. Part A: The Schwarzschild Radius The Schwarzschild Radius is defined as: 2GM (1) = c2 where r, is the Schwarzschild radius, G is the gravitational constant, M is the mass of the black hole, and c is the speed of light. 1. Let's say we have a black hole with a mass 10 times that of the Sun (the Sun's mass is 2 x 1030 kg, so the mass of the black hole is then 2 x 1031 kg). Using the definitions for G and c, what would the Schwarzschild radius of this black hole be? 2. If the radius of the Sun is 7 x 108 m, how does the black hole's radius compare?
