A critical point of a function f (x) is a point where its derivative is zero. A critical point can be a mini- mum or a maximum, distinguished by the sign of the curvature of the function d’f (x)/dx, or a point of inflection.

In order to calculate the heat loss through the wall

Question In order to calculate the heat loss through the wall of a building, it is necessary to know the temperature difference between the inside and outside walls. If temperatures of 50C and 200C are measured on each side of the wall by mercury in glass thermometers with a range of 00C to 500C and a quoted inaccuracy figure of ±1% of full scale reading, calculate the likely maximum possible error in the calculated figure for the temperature difference.

  1. Read all of the book of Philippians in a standard

Question

  1. Read all of the book of Philippians in a standard translation of the Bible as noted in the syllabus. Pay special attention to 2:1-11.
  2. Read Chapter 46 in Jesus is Lord. (You may also review Chapter 2 as well.)
  3. Use Bible Study Tools as a resource.
  4. Write a 400-500 word essay that explains and applies some particular verses out of Philippians 2:1-11:
  5. Start with a brief introductory paragraph that identifies the specific verses you chose to focus on and why you chose those verses.
  6. Study the passage closely and see how it fits into that chapter of scripture. Write approximately 200 words that explain the meaning that your selected verses had for the original author and audience. You should describe the contents of the passage and any points that clarify what it would have meant in its original setting. In the course of your explanation, you must make at least one citation from Jesus is Lord or from an outside resource such as a reputable commentary, which can be found at the Bible Study Tools link (see #3 above).
  7. Then, apply the passage to a contemporary personal or social situation. Write approximately 200 words that make clear links between the original meaning of the passage and the contemporary issue. You may apply the passage to your own spiritual life, family, or job. You can also apply it to larger cultural and societal issues. To complete the application, state clearly what action or stance you would take on your chosen situation or issue based on the contents of the biblical passage.

Question Problem 1:  A particle with charge q = 3e and mass m = 7.6×10-26 kg is injected horizontally with speed 2.9×106 m/s into the region between two parallel horizontal plates. The plates are 36 cm long and 1.4 cm apart. The particle is injected midway between the top and bottom plates. The top plate is negatively charged and the bottom plate is positively charged, so that there is an upward-directed electric field between the plates, of magnitude E = 38 kN/C. Ignore the weight of the particle. Part (a) How long, in seconds, does it take for the particle to pass through the region between the plates? Numeric   : A numeric value is expected and not an expression.t = __________________________________________Part (b) When the particle exits the region between the plates, what will be the magnitude of its vertical displacement from its entry height, in millimeters?Numeric   : A numeric value is expected and not an expression.y = __________________________________________
