What is the acceleration of gravity (g) at the surface of the Sun? (See Appendix E for the Sun’s key characteristics.) How much greater is this than g at the surface of Earth? Calculate what you would weigh on the surface of the Sun. Your weight would be your Earth weight multiplied by the ratio of the acceleration of gravity on the Sun to the acceleration of gravity on Earth. (Okay, we know that the Sun does not have a solid surface to stand on and that you would be vaporized if you were at the Sun’s photosphere. Humor us for the sake of doing these calculations.)
As a person approaches the Schwarzschild radius fo a black hole, outside observers see all the processes of that person (their clocks, their heart rate, etc.) slowing down, and coming to a halst as they reach the Schwarzschild radius. (The person falling into the black hole sees their own processes unaffected.) But the speed of light is the same everywhere for all observers. What does this say about space as you approach the black hole?
How do scientists / astronomers spot a black hole? * A. by using gamma rays and x-rays to detect high energy sources B. by using radioactive waves to detect high energy sources C. By using high energy to detect gamma rays and x-rays D. By using massive telescopes to detect gamma ray
The Sun emits 3.839 x 1026 J of energy every second, which is generated from the fusion of hydrogen into helium in its core. Using Einstein's equation E = mc2 (with c = 2.9979 x 108 m/s), determine how much mass the Sun converts to energy every second due to nuclear fusion in its core. If we assume that the Sun has been shining at this same rate through its entire 4.6 billion year history, how much mass has the Sun lost due to nuclear fusion during its lifetime? Express your answer as a fraction of the Sun's current mass (1.9891 x 1030 kg).
In order to form a black hole, a star must be about how much more massive than our Sun? a. Fifty times as massive b. Ten times as massive c. Twice as massive d. Twenty times as massive e. It actually must be less massive than our Sun
Why does the Sun not collapse under its enormous weight? a) The Sun is about 4.6 billion years old. If it could have collapsed by now , it would have. b) Because the Sun is in hydrostatic equilibrium. c) Because the Sun is not in hydrostatic equilibrium. d)More than one of the above.
A neutron star is a cold, collapsed star with nuclear density. A particular neutron star has a mass twice that of our Sun with a radius of 12.0 km. (a) What would be the weight of a 100-kg astronaut on standing on its surface? (b) What does this tell us about landing on a neutron star?
Certain wavelengths in the light from a galaxy in the constellation Virgo are observed to be 0.4% longer than the corresponding light from Earth sources. (a) What is the radial speed of this galaxy with respect to Earth? (b) Is the galaxy approaching or receding from Earth?
In order to form a black hole, a star must be about how much more massive than our Sun to form a black hole? A) twice as massive B) ten times as massive C) it actually must be less massive than our sun D) Twenty times as massive
Our Sun shines bright with a luminosity of 3.828 x 10^26 Watt. Her energy is responsible for many processes and the habitable temperatures on the Earth that make our life possible. (a) Calculate the amount of energy arriving on the Earth in a single day. (b) To how many litres of heating oil (energy density: 37.3 x 10^6 J/litre) is this equivalent? (c) The Earth reflects 30% of this energy: Determine the temperature on Earth’s surface. (d) What other factors should be considered to get an even more precise temperature estimate? Note: The Earth’s radius is 6370 km; the Sun’s radius is 696 x 10^3 km; 1 AU is 1.495 x 10^8 km.
Is the event horizon of a black hole the actual physical surface of the object?
