- Mehul1. What is wave-particle duality? How does it apply to photons and electrons? Why do we not generally observe this in everyday life? 2. What is the Hubble Law? What does it say about the evolution of the universe? What does it have to do with redshift?What is the escape velocity (in km/s) from the surface of 1.1 M neutron star? (hint: Use the formula for the escape velocity Ve = 2GM/R ; make sure to express quantities in United of meters, kilograms, and seconds. Assume a neutron has a radius of 11 km and assume the mass of the sun is 1.99 x10^30 kg.) 1.1 M neutron Star = _________ km/s 3.0 neutron Star = __________ km/s
- What is the only viable explanation for so much mass in so small a region at the core of our galaxy? a. a tight cluster of stars b. many neutron stars c. many stellar black holes d. a single massive black hole e. none of the above11. Bob is traveling in a space ship and observes emission from a cloud of atomic hydrogen gas a few light years away. He identifies the Balmer-beta emission line (from the n = 4 to n = 2 transition) and measures its wavelength to be 322 nm. How fast is Bob moving relative to the cloud of hydrogen? Is he getting closer or further away from the hydrogen cloud? (You may assume that Bob is moving directly toward or away from the hydrogen gas cloud. Recall that the ground state energy of hydrogen is -13.6 eV.)1: Briefly explain what are neutron stars and then estimate the escape velocity of a neutron star.
- Describe each of the following in detail, indicating their respective origins and the differences between them: Nova, Supernova type 1, Supernova type II.What are gravitational waves, how are they generated, what do they do and how can we detect them? Please thoroughly explain. Please include a diagram(s) for these questions. If you use any sources, please list them. Thank youWhich of the following most correctly explains why we have not yet observed any white dwarfs derived from M stars: Group of answer choices Most M stars end up as neutron stars or black holes. The lifetime of M stars is longer than the age of the universe. Most M stars are located near the edge of the universe, beyond the visible horizon. Most M stars are members of a binary system, and the white dwarf would be obscured by the glare of the more massive companion. White dwarfs are too dim to be observed with currently available techniques.
