Document Summary

Whatever is clearly and distinctly perceived is true if god exists. Idea of god + causality (cause must have at least as much reality as the effect). Objective = representative reality of an idea. E. g. , infinite substance, finite substance, attribute, or mode. To remain with intelligible things: ideas (iv) Nothing can be known with greater clarity and distinctness than god. 2nd: truth about objects in the external world. God cannot be a deceiver because deception is a sign of imperfection. Whatever is clearly and distinctly perceived is true. Nothing clearly and distinctly perceived is false. Error and ignorance are not real and positive ideas. To be an error means the lack or absence of some knowledge. Each cause taken separately would not be the cause for error; need both. We say yes and no to things that are outside our understanding. If we affirm what is clearly and distinctly perceived we cannot make mistakes.

A bit of computer memory is some physical object that can be in twodifferent states, often interpreted as 0 and 1. A byte is eightbits, a kilobyte is 1024 bytes, a megabyte is 1024 kilobytes and agigabyte is 1024 megabytes.
a: Suppose that your computer erases or overwrites one gigabyte ofmemory, keeping no record of the information that was stored.Explain why this process must creatte a certain minimum amount ofentropy, and calculate how much.
b: If this entropy is dumped into an environment at roomtemperature, how much heat must come along with it? Is this amountof heat significant?

1. Write at least one paragraph in which you define diffraction andinterference, discuss Huygens' Principle and explain why lightpassing through a narrow slit or set of fine slits will produce apattern on a wall.
2. Diode lasers produce a range of wavelengths. Do you think usingthe average made much difference in your calculations? Explain indetail.
3. How would the pattern on the wall have been different if you hadused a helium-neon laser which only produces light of onewavelength?
4. What would the diffraction pattern look like if the light youused was composed of several specific wavelengths?
5. In order to have a clear diffraction pattern the slit must bearound the same order of magnitude as, but not smaller than thewavelength of the light. What is the ratio of single slit width towavelength for your experiment? How would the pattern on the wallchange if you could gradually widen the slit?
Please show me step by step, thank you so much for your help

4. A -2q charge is located a distance d to the right of a +4qcharge, along the x
axis. At which point (or points) along the axis does the electricfield go to zero? To
solve this problem, consider an observer at point P, which is anarbitrary distance x from the +4q charge. Find the value (orvalues) for x (in terms of the separation distance d) where thetotal electric field vanishes.
(a) The electric field is never zero in the vicinity of thesecharges.

in a region of space that contains an electric field?

(c) A positive charge will gain kinetic energy as it approaches anegative charge.
(d) The work required to bring two charges together is independentof the path taken.
(e) A negative charge will gain kinetic energy as it moves awayfrom another negative charge.
