Astronomy question.

You are given a list of 10 stars and their temperatures. Assuming that the list is chosen at random from all the stars in our Milky Way galaxy, will the list contain more low-temperature or high-temperature stars? Explain your reasoning.

I need a knowledgable person in astronomy, who can answer the following questions. Stellar nurseries are massive regions of star formation much like the region in which our own star formed. Once these baby stars form they eventually get gravitationally ejected from the region and move into interstellar space. Stars are formed in bundles in this regard and our Sun likely has numerous brothers and sisters that formed from the same cloud as ours. They are out there independently revolving...

Our solar system is roughly 2.28 x 1020 m away from the center of the Milky Way galaxy, and the system is moving at roughly 227.7 km/s around the galaxy's center. Since most of the galaxy's mass is near its center (and we are on an outer arm of this spiral galaxy), let's model the galaxy has a spherical mass distribution (like a single, giant star that our system is orbiting around). What is the mass of the galaxy (according...

The stars, gas and dust in a galaxy rotate about the center of the galaxy. We would like to know exactly how to describe the rotation of all parts of the galaxy. In other words, we want to know if galaxies rotate like merry-go-rounds, or like planets orbit the Sun, or in some other way. 1. Do points near the center of a merry-go-round complete a full rotation in the same amount of time as points near the outer edge...

Is there strong evidence of global warming? Let's consider a small scale example, comparing how temperatures have changed in the US from 1968 to 2008. The daily high temperature reading on January 1 was collected in 1968 and 2008 for 51 randomly selected locations in the continental US. Then the difference between the two readings (temperature in 2008 - temperature in 1968) was calculated for each of the 51 different locations. The average of these 51 values was 1.1 degrees...

QUESTION: A) In week 1 you calculated the mean number of hours on electronic devices for the 10 people in your personal sample. Use this value as the starting point to create a 90% confidence interval for the number of hours a day on electronic devices a person has. The actual average of our class data is 6.2 hours (with standard deviation of 3.4). Does your confidence interval contain the actual value? Discuss your results with your reasoning as to...

3/ which of the following stellar properties is the most fundamental to a star’s main-sequence and post-main sequence life? A/ temperature B/ mass C/ luminosity D/ radius 4/ Stars Moppit and Boppit orbit each other as members of a binary star system. Their period of rotation about their combined centre of mass is 10 years. The semi-major axis of Boppit’s orbit around the centre of mass is 15.25 AU. What is the combined mass of Moppit and Boppit? A/ Mmoppit...

1. Suppose you had 10 identical molecules enclosed by a box. At a given instant, one molecule has an energy of 100 Joules, and the others are all stationary. (A) What is the average kinetic energy of the 10 molecules? (B) Is this a situation of high or low entropy? (C) What happens to the energy and entropy of the molecules in the box as time passes? Does your answer depend on the insulation of the box? 2. Which is...

A )When pollsters take a random sample of about 1000 people to estimate the mean of some quantity over a population of millions of people, how is it possible for them to estimate the accuracy of the sample mean? B) Under what conditions, if any, is it not correct to assume that the sampling distribution of the sample mean is approximately normally distributed? Explain your reasoning. C)Suppose that you want to know the opinions of American secondary school teachers about...
