2. Above a charge on a wire loop created an electric field. Now imagine a wire loop in an electric field. a. Draw a diagram to show the relative orientation of the loop and the electric field so that the number of field lines that pass through the surface of the loop is maximum possible. b. Draw a diagram to show the relative orientation of the loop and the electric field so that the number of field lines that pass through the surface of the loop is minimum possible.

Explain The Regress Argument’ for Foundationalism. Why does Dancy hold that this argument is fallacious? Is he right? One of the primary questions concerning epistemology is that of how we justify true beliefs? The regress argument is a problem imbedded in epistemology and‚ in general‚ a problem in any given situation where a statement or belief has to be justified. The Regress argument starts with the idea that some beliefs are justified by reference to others. "All agree that some of our beliefs

requesting service. Now that the variables are decided the process of building the array can begin. An array must have an Upper Bound. This simply means a limit for the number of times that the loop will run before the program ends. Without this set limit the program would become an infinite loop. Having an infinite loop could likely cause the program to crash in some cases‚ but it is the opinion of this writer that all that would happen in the case of this program would just mean that the user would be

Time may well be the most complex phenomenon known to mankind. Scientists know many things about it yet at the same time know very little. One conclusion‚ however‚ is pretty straight forward. Time travel at least the kind that would be of any use to us is just not possible. Firstly we will focus on a few ideas and questions about time travel. One major question asked by people is: if time travel exists where are all the time travelers? This does seem to be an exceptional question. If
