Select all the correctly defined terms. (Hint: do not select the ones that are incorrectly defined) Law of conservation of energy presumes the total energy content of the universe is constant. Kinetic energy is attributed to the motion of the obicet and depends on the mass of the object and its velocity. Potential cnergy is the energy associated with position or composition. Heat involves the transfer of energy between two objects due to a temperature difference. Work is a force acting over a distance Could also be transfer of cnergy from onc form to another

Since the time of Copernicus, each revolution in astronomy has moved humans farther from the center of the universe. Now it appears that we may not even be made of the most common form of matter. Trace the changes in scientific thought about the central nature of Earth, the Sun, and our Galaxy on a cosmic scale. Explain how the notion that most of the universe is made of dark matter continues this “Copernican tradition.”
Calculate the number of seconds in a year (365 days). Express your answer in standard exponential notation, with three significant figures.
Choose a unit distance in cm that would easily fit on a piece of paper. Let this be your scale distance, now divide your scale distance by 4.3 light years to get the scale that will allow you to convert between real distances and distances in your model
We are going to make a simple approximation of the number of atoms in the universe. Assume all the atoms in the universe are hydrogen. (In actual practice, over 75% of the atoms in the universe are hydrogen.) Assume the sun is a typical star (made of pure hydrogen) has a density of 1.4 g/cm3 and is a sphere with a radius of 7.0*108m Assume that there are 100 billion stars in our Milky Way galaxy that are identical to our sun. Assume that there are 10 billion galaxies in the universe identical to our Milky Way galaxy. How many atoms are there in the universe?

The handwriting or solutions please make it clear (readable) please thank you 1. Why is the equation PE = mgh cannot be used to get the potential energy anywhere in the universe? A. Mass is not constant on every part of the universe. B. It is only used for objects near the surface of Earth. C. Height cannot be determined. D. Acceleration is constant for every part of the universe.

A light-year is the distance that light can travel in one year. Similarly, we can define a light-second, light-day, etc. as the distance that light can travel in other time intervals. Calculate the distance represented by each of the following: (Assume that the speed of light is 3 x 10^8m/s) 5 light-minutes 6 light-days 6 light-days, but this time answer in miles (enter just the number with no units)
