It was formed what is the electric potential at the surface of the sphere? Which of the following statements BEST describes cosmic microwave background radiation? False. SURVEY . Which of the following statements about relativity is NOT true? hand, stars were evolved after the big-bang for a million years Which of the following statements about the cosmic background radiation is not true? (b) How many antinodes are in the standing wave at 51.87 Hz? B) It is the result of a mixture of radiation from many independent sources, such as stars and galaxies. On the other A) the universe has a center B) the universe will eventually begin to contract C) the universe has a finite volume D) the universe has no boundary which of the following lamps would be the best source for 632.8 nm light, how to find the mass of an object in physics. How do you convert velocity m/s to angular velocity? Which of the following statements would be FALSE? A) It has a temperature of about 3 degrees K above absolute zero. C. It is the combined starlight of the most distant galaxies. f the following are true of the True False fills the entire Universe today has a temperature of -3000 K comes from all directions discovered in the 1960s with a radio telescope consists of many spectral emission lines Which of the following statements about the cosmic background radiation is not true? (e) The CBR is inconsistent with the steady-state theory of the Universe. It is much brighter towards the center of the galaxy. A student uses an audio oscillator of adjustable frequency to measure the depth of a water well. © 2003-2020 Chegg Inc. All rights reserved. Explain. was the earliest radiation detected by the scientists. D.Unlike stars and galaxies, it is unaffected by redshift. Such fluctuations were found in the COBE data. The student reports hearing two successive resonances at 51.87 Hz and 59.85 Hz. CBR stands for Cosmic Background Radiation. A) It has a temperature of about 3 degrees K above absolute zero. (a) The CBR shows that the early Universe was highly (but not perfectly) homogeneous and isotropic. Cosmic microwave background (CMB), also called cosmic background radiation, electromagnetic radiation filling the universe that is a residual effect of the big bang 13.8 billion years ago. Tags: Question 22 . A. (b) There are small variations in the CBR that correspond to slight differences in density from which galaxies, superclusters, and voids eventually formed. B) It appears essentially the same in all directions (it is isotropic). True. SURVEY . C) at the time the cosmic background radiation was formed D) during the first ten minutes of expansion Suppose our universe has positive curvature. It (a) The CBR shows that the early Universe was highly (but not perfectly) homogeneous and isotropic. This is an alternate ISBN. C) It had a much higher temperature in the past. asked Sep 24, 2016 in Physics & Space Science by craftychris. Q. 60 seconds . 60 seconds . (d) The CBR was produced by the first few generations of stars in the early Universe. At speeds close to the speed of light, a moving clock runs slower than a stationary one from the perspective of a stationary observer Gravity is a warping of space-time that happens in the presence of mass In view of the importance of cosmic microwave background radiation to the Big Bang model of the universe (no other model has explained CMB quite so neatly), efforts were redoubled in an attempt to definitively prove the connection, first in the form of the Cosmic Background Explorer (COBE) satellite in 1989, and then the Wilkinson Microwave Anisotropy Probe (WMAP) in 2001. 1902-365 Bloor St East, Toronto, ON M4W 3L4. What is the universe’s estimated age? after CBR only. Multiple choice: Which one of the following statements about the cosmic background radiation (CBR) is false? Tags: Question 16 . What is Middle C in frequency Hz for Piano? 8 Which statement about the cosmic microwave background is NOT true Hint Its from EEE EE8086 at Nanyang Technological University
