3. Collapsing Cloud. a. The time it takes for a cloud 100,000 AU in diameter to collapse to form a new star turns out to be about half the time it would take an object to orbit the star on an elliptical orbit with a semi-major axis of 50,000 AU (half the 100,000 AU diameter). Use Kepler’s third law to find the collapse time, assuming the star has the same mass as the sun.
b. Evidence indicates that the inner planets formed in about 30 million years. Compare this to your answer above. Which process takes longer? Explain why?

A planet is discovered to orbit around a star in the galaxy Andromeda, with the same orbital diameter as the Earth around our Sun. If that star has 4 times the mass of our Sun, what will the period of revolution of that new planet be, compared to the Earth's orb o One-fourth as much o One-half as much Twice as much A.

3. A Renaissance astronomer, Johannes Kepler, observed that the amount of time that a planet takes to travel around the Sun T is proportional to the 3/2 power of the long axis of its orbit. We are not equipped to analyze this for general orbits. However, we can calculate this for a circular orbit. Consider a planet of mass m orbiting a star of mass M in a circular orbit of radius r. Find the relationship between the time T...

2) Planet Velocities and Energy (10 pts) We talked about how planet formation involves the collisions of bodies (planetesimals, embryos) leading to the growth (and heating) of a planet. Let's think about the velocities and energies involved here. a) The speed of a body in its orbit around the Sun is given by the equation V2= GM.[(2/r) - (1/a)] Here Vis the speed of the body in m/s, G is the gravitational constant, M. is the mass of the Sun...

1. All the planets orbit the Sun in the same direction. This is strong evidence that: Group of answer choices None of these is correct. We do not have any idea yet why the planets are orbiting in the same direction. the solar system resulted from the collision of two medium-sized stars. after the planets formed, collisions between them eventually caused them all to move in the same direction. the planets were formed elsewhere in the galaxy and were later...

Case: Enron: Questionable Accounting Leads to CollapseIntroductionOnce upon a time, there was a gleaming office tower in Houston, Texas. In front of that gleaming tower was a giant “E,” slowly revolving, flashing in the hot Texas sun. But in 2001, the Enron Corporation, which once ranked among the top Fortune 500 companies, would collapse under a mountain of debt that had been concealed through a complex scheme of off-balance-sheet partnerships. Forced to declare bankruptcy, the energy firm laid off 4,000...

10. Write a one-page summary of the attached paper? INTRODUCTION Many problems can develop in activated sludge operation that adversely affect effluent quality with origins in the engineering, hydraulic and microbiological components of the process. The real "heart" of the activated sludge system is the development and maintenance of a mixed microbial culture (activated sludge) that treats wastewater and which can be managed. One definition of a wastewater treatment plant operator is a "bug farmer", one who controls the aeration...
