ENPH 217: TAMU ‐ CS Campus Dr. J.A. Cornejo FAL23 Homework No. 04 Due: THUR 10/19/23 Student Name DEPT Code Section No. ENGR or PHYS Remember! To receive full credit for any problem, you must show all work, pertinent mathematical derivation(s), steps followed or procedure (only when applicable), and clearly defined result with the correct units. All work must be legible! If the PTs or I are unable to read it, it’s wrong. Failure to show clear engineering, mathematical or physics logic in your solution will forfeit full credit for the problem. Problems and individual parts of multi ‐ part problems will generally be graded based on the following simplified scale: E : Excellent ( 4 points ): Excellent effort . Problem completed and numerical answer & units correct. Superior understanding of material, mathematical concepts and sound engineering logic is evident. S : Satisfactory ( 3 points ): Good effort . Problem essentially completed with correct setup. Numerical answer or units slightly incorrect or missing. Good understanding of material, mathematical concepts, problem and solution methodology is evident. Displays satisfactory engineering logic. N : Needs improvement ( 1 ‐ 2 points ): Minimal effort . Problem partially done. Setup partially correct. Numerical answer or units incorrect or missing. Minimal or incomplete understanding of material, mathematical concepts and problem/solution methodology. U : Unsatisfactory ( 0 points ): No effort . Problem/problem part not done or essentially not done. Numerical answer missing or absolutely incorrect (completely off). No evidence of understanding the material or solution methodology . Assignment Begins on Next Page Academic Integrity Statement By submitting an assignment (electronic, hard-copy or any acceptable format) with your name and UIN, you are agreeing and are bound to the academic integrity statement set forth here. As a student at Texas A&M University, you agree to honor and follow the Aggie Code of Honor ( University Rules, §20.1.2.1 ): “An Aggie does not lie, cheat or steal, or tolerate those who do.” You may collaborate with your peers on applicable assignments or projects to a reasonable extent , but you must submit your own original work. Clear indication of copying from another student, solutions manual, online website, homework “help” service (e.g. “Chegg” ™) or any academic dishonest enterprise will result in an automatic ZERO for the assignment and you will be reported to the Aggie Honor System Office for review. If you are complicit in any academically dishonest activity of any form, you will also be held accountable for your participation, even if it is not your assignment. Thus, you agree to follow ethical practices in preparation for your career as a future engineering professional.
