Astronomy 10 Chapter 11 1. Both used to be normal stars but the white dwarf ran out of hydrogen, they are both subjected to gravitational theories. A Neutron star is a fluid of neutrons, as hot at its surface as the inside of the sun and has a greater magnetic field. 3. Because its density is so high, neutrons spin in the same way that electrons do so must obey the Pauli Exclusion Principle.
Which of the following planets is NOT a gas giant? a. Earth b. Jupiter c. Saturn d. Uranus 16. The sun gets its energy from a. burning fuel b. nuclear fusion c. shrinking due to gravity d. convection 17. The number of on any planet can be used to estimate how old the surface is.
Describe two ways in which gravity has a part in the life-cycle of a star- Gravity pulls the dust and gas in the nubula together, and compresses them so much that the inside becomes hot enough for fusion reactions to start. Gravity also pulls the remains of a red giant together after fusion reactions have stops. This forms a white dwarf. Theories about the universe- 1. What does red shift tell s about distant galaxies?
AUCKLAND UNIVERSITY OF TECHNOLOGY THE EXISTENCE OF BLACK HOLES WHAT ARE BLACK HOLES? DO THEY REALLY EXIST? TEVITA PAEA ID: 0102315 LITERATURE REVIEW ESSAYS “WHAT ARE BLACK HOLES?DO THEY EXIST? : If they do, HOW ?”If not: HOW?” Our solar system consists of ten planets revolving around the Sun. The Sun serves as a magnet that uses its gravitational pull to hold the solar system together.
Gravitational acceleration was found using this formula: g=2ht2 Impact speed of the falling objects was found using this formula: v=2ht Percentage error between calculated values and those obtained from the slope of the graphs were found using this formula: percent error=calculated value-slopecalculated value x100% PROCEDURE Firstly we placed the falling sphere apparatus on the table. Then we placed the meter scale next to the falling sphere
The theory of Black Holes and its process is one of the most unique studies of the universe, in that with each discovery made, we un-lock closed doors to knowledge of how the universe was made. In 1798 a French Mathematician Pierre Simon de Laplace came up with the first theory of a Black Hole. He agreed with Newton, that when enough mass is added to a star like the sun, the gravitational pull would become so great that the escape velocity would equal the speed of light. Therefore, the star would blink out and become an invisible star. More than a century later, Einstein, came up with the theory of relativity.

Show all your work. 10. Calculate the atomic mass of the element X. Then use the periodic table to identify the Mass contribution ( ؍mass)(percent abundance) 69Ga: (68.9257 amu)(60.12%) 44.14 ؍amu 71Ga: (70.9249 amu)(39.88%) 82.82 ؍amu Atomic mass of Ga 44.14 ؍amu ؉ 28.28 amu 27.96 ؍amu has a relative abundance of 60.12% and an atomic mass of 68.9257 amu. 71Ga has a relative abundance of 39.88% and an atomic mass of 70.9249 amu.
At the very start, the entire universe was about a size of an atom. It was termed by Georges Lemaitre as the “primordial atom”. As one of the pioneers of in the make of the big bang theory, Georges Lemaitre proposed this new theory. At that time, this theory has explained many difficulties that were met by the theories proposed previously. For example, a theory states that the universe is infinitely large with an infinitely amount of stars was met by the Olber’s paradox.
Also, for every force, there is an equal and opposite force acting against it. With the exception of gravity, the electromagnetic force is the force responsible for practically all the encounters in daily life above the nuclear scale. Roughly speaking, all the forces involved in interactions between atoms can be explained by the electromagnetic force acting on the electrically charged atomic nuclei and electrons inside and around the atoms, together with how these particles carry momentum by their movement. This includes the forces we experience in pushing or pulling ordinary material objects, which come from the intermolecular forces between the individual molecules in our bodies and those in the objects. With the exception of gravity, electromagnetic phenomena as described by quantum electrodynamics account for almost all physical phenomena observable to the human senses, including light and other electromagnetic radiation, all of chemistry, most of mechanics (excepting gravitation), and, of course, magnetism and electricity.
