Ut Homework Service Quest Moving

Quest Learning & Assessment is a non-profit organization at the University of Texas at Austin College of Natural Sciences maintaining a web-based tool for instructors and students of mathematics and science. Originally created as the UT Physics Homework Service as early as 1991,[1] the system was updated and moved to the College of Natural Sciences[2] in 2002 to provide service to the broader array of STEM courses. It is being used at over 1,000 U.S. institutions; high schools as well as 2-yr/4-yr colleges and universities.[3]

Questions and Assignments[edit]

Instructors can create homework, quizzes and exams from a large pool (over 75,000)[4][5] of Mathematics, Physics, Biology, Chemistry, Physical Sciences and Computer Science questions. Most questions have built-in variations, so Quest can create custom assignments for each student. Students get immediate feedback when answering questions and can view step-by-step solutions after the assignment due date has passed.

Grading system[edit]

The default grading system uses a "guessing neutral" system similar to the SAT grading scheme. Instructors also have the ability to set the grading system to an "item neutral" scale where points are not deducted from the assignment for failed questions. If a student gets an answer correct they are awarded points, however points are subtracted for incorrect answers to discourage guessing in both of these models. Additionally, instructors can use "One Free Try" grading in order to encourage students to re-try a question before being penalized.

Version 001 – Electrostatics I – tubman – (12125) 1 This print-out should have 13 questions. Multiple-choice questions may continue on the next column or page – fnd all choices beFore answering. AP EM 1993 MC 55 001 10.0 points Two metal spheres that are initially un-charged are mounted on insulating stands, as shown. X Y − − − − A negatively charged rubber rod is brought close to but does not make contact with sphere X . Sphere Y is then brought close to X on the side opposite to the rubber rod. Y is allowed to touch X and then is removed some distance away. The rubber rod is then moved Far away From X and Y . What are the fnal charges on the spheres? Sphere X Sphere Y 1. Positive Positive 2. Positive Negative correct 3. Negative Negative 4. Zero Zero 5. Negative Positive Explanation: When the negatively charged rod moves close to the sphere X , the negatively charged electrons will be pushed to sphere Y . IF X and Y are separated beFore the rod moves away, those charges will remain on X and Y , so X is positively charged and Y is negatively charged. AP EM 1998 MC 39 40 002 (part 1 of 2) 10.0 points Two charged particles oF equal magnitude (-Q and-Q ) are fxed at opposite corners oF a square that lies in a plane (see fgure below). A test charge-q is placed at a third corner.-Q-q-Q What is the direction oF the Force on the test charge due to the two other charges? 1. 2. 3. correct 4. 5. 6. 7. 8. Explanation: The Force between charges oF the same sign is repulsive and between charges with oppo-site signs is attractive.-Q-q-Q The resultant Force is the sum oF the two vectors in the fgure.
