ECS1501 ASSIGNMENT 6 QUESTIONS AND ACCURATE ANSWERS 2023/2024 NEW UPDATE You would expect millisecond pulsars to be a) most common in open clusters. b) collapsing rapidly. c) part of a binary system. d) rotating slowly. e) isolated in space. - CORRECT ANSWER ==c) part of a binary system. An observer on a planet sees a spaceship approaching at 0.5c (where c is the speed of light). A beam of light projected by the ship would be measured by this observer to travel at a) 2.5c. b) c. c)...

Hydrostatic Equilibrium The current distinguishing criterion between dwarf planets and small Solar System bodies Evolution of stars of different mass -Star formation produces a wide variety of stars -Only a few high-mass stars (O, B Type) are produced -The lowest mass stars (eg.M type) are the most common. -If a "star" forms with a mass less than about 1/10 the mass of the Sun, it will not have enough pressure in its core to ignite nuclear fusion. •The lower limit to the mass of a...

IXL Determine the main idea of a passage questions and answers 100% correct While excavating a tunnel under Mexico's Naica Mountain, silver miners were stunned to discover a cavern full of luminous, elongated underground crystals. Composed of the mineral gypsum, some of the crystals extended as far as thirty-six feet into the air. What accounted for these amazing mineral structures? Millions of years ago, volcanic eruptions released a large amount of mineral-rich water into the cave, now known...

Astronomy Unit 6 Exam - Questions & Answers How can a white dwarf create a nova? A white dwarf that is part of a binary system can undergo repeated novas by consuming material from a main-sequence companion star. Describe the steps that the sun will follow for its evolution. Be able to draw its path on an H-R diagram. Nebula, Protostar, Main Sequence, Red giant, White Dwarf, Black Dwarf. (Up on the right, down, then up again til the middle of the graph, then slight down angle to the left, steep...
