Textbook Question
Chapter 5, Problem 25EAP
Does It Make Sense?
Decide whether the statement makes sense (or is clearly true) or does not make sense (or is clearly false). Explain clearly; not all of these have definitive answers, so your explanation is more important than your chosen answer.

Students have asked these similar questions
1. 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?
Based on what you have learned about galaxy formation from a protogalactic cloud (and similarly star formation from a protostellar cloud), the fact that dark matter in a galaxy is distributed over a much larger volume than luminous matter can be explained by
I. Dark matter does not emit EM radiations.
II. The pressure of an ideal gas decreases when temperature drops.
III. The temperature of an ideal gas decreases when its thermal energy decreases.
A. I only
B. I and III only
C. II and III only
D. I, II and III
Is the answer C? Thank you!
Question A7
State three pieces of evidence that support the idea that the Universe began in a hot Big Bang,
and explain how each piece of evidence supports the hot Big Bang model. Describe the ob-
servational evidence that supports the idea that the Universe is pervaded by Dark Energy, and
explain why each piece of evidence you cite supports the Dark Energy model.

A galaxy cluster has a galaxy behind it whose image we see as being smeared out and curved, with an angular radius of curvature on the sky of θE. The background galaxy is at redshift zgal and the cluster is at zclust. What is the mass of the cluster in solar masses? Give your response in scientific notation with one decimal place. (The Hubble constant is of course 70 km/s/Mpc, and you can assume the Hubble law for these low redshifts). Values: zgal = 0.11 zclust = 0.07 θE = 117.4 arcsecondsarrow_forward

- Astronomy Question: Read the questions slowly and answer with precise and long details about each of the questions. Answer correctly and follow my guidelines for a long and wonderful review after results. Your target/main observable galaxy is the whirlpool galaxy. Target: Whirlpool Galaxy Object Type: Galaxy Distance: 37 million light-years Constellation: Canes Venatici. DO NOT COPY AND PASTE OTHER WORK OR THINGS FROM THE INTERNET, use your own words. In 500 words, please explain the relevance of this object to the physics course material in university andits importance to astronomy. (Some question you may seek to answer are: What beyond the objectitself is learned by studying this class of objects? What sorts of telescopes and observations would beneeded for more detailed, broader reaching studies of this source and objects of its nature?)arrow_forwardHubble's First Attempt. Edwin Hubble's first attempt to measure the universe's expansion rate was flawed because the standard candles he was using were not properly calibrated. Look at (Figure 1) a.Estimate the value of Ho corresponding to the solid line in the figure. Express your answer kilometers per second per million light-years to two significant figures. b.What is the approximate age of the universe indicated by that erroneous value of Ho? Express your answer in years to one significant figure.arrow_forward38. The Cosmic Microwave Background is remarkable in many ways. Let's illustrate this by personalizing the CMB a bit. a) Imagine that the Earth is a sphere with a radius equal to its actual equatorial radius (The radius of Earth at the equator is 3,963 miles (6,378 kilometers). If the radius of the Earth is assumed to be constant to the same level of uniformity as the temperature fluctuations of the CMB—that is, to one part in 100,000—then how high would the highest mountains be relative to the mean surface radius of the Earth? b) Calculate the ratio of the age of the Universe when the CMB was created and the age of the Universe today (in late 2021). If a person is 20 years old, What was their age relative to their current age adopting that fraction? Give the result in hours.arrow_forward
