Astronomers use the distance modulus function M(r) = 5 log r − 5, where M is the distance modulus and r is the distance of a star from Earth in parsecs. (One parsec is approximately 1.92 1013 miles, or approximately 20 trillion miles.) Use this function to answer the question below. Round to the nearest tenth.The distance modulus of "Star Alpha" is −1.21. How many parsecs from Earth is this star?
Variable stars are ones whose brightness varies periodically. The brightness of a certain star is modeled by the function b(t) = 8.2 − 2.7 cos ((pi/155)t) where t is measured in days. (a) Find the period. days(b) Find the maximum and minimum brightness. (minimum) (maximum)

The distance from the Sun to the nearest star is about 4 1016 m. The Milky Way galaxy (Fig. P1.56) is roughly a disk of diameter 1021 m and thickness 1019 m. Find the order of magnitude of the number of stars in the Milky Way. Assume the distance between the Sun and our nearest neighbor is typical. Figure P1.56 The Milky Way galaxy.
That did answer a lot of questions. Thank you. But where do you derive the equation E=(K|q|)/r? My book says E=(K|q|)/r^2. I tried re-arranging some equations to get your equation, but I can't figure it out. Thanks.
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?

A new physics unit of distance is created and called the Zarkov. A student informs you 1 Zarkov (1 Za) is exactly equivalent to 8 inches. Convert 4.44 × 10 5 Z a 3 m i n u t e 2to m 3 h r 2. If hard to read: asking you to convert Zarkov's squared over minutes cubed to meters squared over hours cubed. Answer in E notation without units in the box. I am assuming your output units are m 3 h r 2. Note: for some numbers the computer will convert your E notion to another notation without the E...that will not cost you points. To be clear regarding E notation, I will provide an example of what I'm talking about:

The area of a circle is given by ar? where r is the radius. This can be written as area = (ar) x r. Can we regard this equation as being of the form: z = xy 1 PHY1509 PHYSICS SECTION: UNIQUE NUMBER (714489) where z = area, x = ar and y = r so that one can use equation (10.12) or (10.13) instead of equation (10.15) for determining the error in the area?
