D 2. 2/2 points Two vectors, and are equal: = Which of the following statements are true? Choose all that apply. http:[email protected][email protected] Page 1 of 3 Vector review, syllabus F2008 10/30/08 11:05 PM The directions of and may be different the z-component of must be equal to the z-component of The unit vector must be equal to the unit vector . the x-component of must be equal to the x-component of the y-component of must be equal to the y-component of The magnitudes of and may be different 3. 7/7 points = < 3, 0, 5 >m. | | | | = < -2, 5, 0 >m. >m. + =< 1 , 5 , 5 | = 5.83 m | = 5.38 m + | = 7.14 m | + | | = 11.21 m 4. 7/7 points A proton is located at <-5e-10, 8e-10, -2e-10> m. An electron is located at <8e-10, -2e-10, 9e-10> m. (a) What is , the vector from the electron to the proton? = < -13e-10 , 10e-10 , -11e-10 > m (b) What is the magnitude of ? | | = 1.97e-9 m (c) What is , the unit vector (vector with magnitude 1) in the direction of ? = < -.658 , .51 , -.557 > 5. [MI2 01.X.14] 4/4 points If = < 3, -3, 7 >, then what is 8* ? 8* = < 24 , -24 , 56 > How does the magnitude of 8* compare to the magnitude of ? The magnitude of 8* is a factor of 8 less than the magnitude of . Not enough information is given. The magnitude of 8* is the same as the magnitude of . The magnitude of 8* is a factor of 8 greater than the magnitude of . The magnitude of 8* is zero. 6. 3/3 points Read the course syllabus and look at the course calendar, both of which are available on the course website, to find the answers to these questions about the lab component of this course. When do labs start? Monday, August 25 Monday, September 1 Monday, September 8 I forgot to go to my lab. How can I make it up? I can attend any other lab section I choose Missed labs cannot be made up I can attend a makeup lab at the end of the semester
http:[email protected][email protected] Page 2 of 3 Vector review, syllabus F2008 10/30/08 11:05 PM I can attend a makeup lab at the end of the semester What if I am seriously ill, or on a university-sponsored trip? I don't need to do anything about this until the end of the semester. I must immediately give documentation to my lab TA, who can let me make up the lab. I must immediately give documentation to my lecture instructor, who can give me a signed permission slip to attend a different lab, or excuse me from the lab. 7. 3/3 points Read the course syllabus and look at the course calendar, both of which are available on the course website, to find the answers to these questions about the tests in this course. When are the tests in this course given? During regularly scheduled lab times Tuesday evenings at 7:30 PM Wednesday evenings at 5:00 PM During regularly scheduled lecture times What percentage of your final grade is contributed by your lowest test score? 9 What percentage of your final grade is contributed by each other test score? 12 % % 8. 3.5/3.5 points Read the course syllabus and look at rest of the course website to find the answers to these questions about this course. How can I get help in this course? Choose all that are true. See my lecture instructor during his or her office hours Go to the tutoring center in Fox Hall Ask a question in the online course forum Go to TA help sessions from 5-7 PM Mon-Thur in Riddick 415 What percentage of my grade is contributed by: Homework 13 % Lab 13 % Tests 45 % Lecture Attendance 4 % Final Exam 25 % http:[email protected][email protected] Page 3 of 3 ...
