2. [10pts) The surface brightness of an astronomical object is its observed flux divided by its observed angular area as ~f/(802. For a class of objects that are both standard candles and standard yardsticks, how does the surface brightness of these sources scale as a function of redshift? For example, you may express your results similar to . « (1 + 2) where the symbol a means 'proportional to'.

Question 1) Consider a class Point that models a 2-D point with x and y coordinates. Define the class point that should have the following Private data members x and y (of type int), with default values of 0 A constant ID of type int A private static integer data member named numOfPoints This data member should be o Incremented whenever a new point object is created. o Decremented whenever a point object is destructed. A default constructor An...

Introduction Your eighth assignment will consist of two programs, which will involve the use of simple classes. The source code for these problems should be submitted using the naming conventions we specified in class. Please note that your computer programs should comply with the commenting and formatting rules as described in class. For example, there should be a header for the whole program that gives the author's name, class name,...
