The field in E is that of attraction between point changes. The field shown at B shows repulsion between the field lines. The repulsive effect is due to a pair of like charged particles. 11. The correct answer is D . The parallel field lines shown in the diagram are from a pair of parallel plates. 12. The correct answer is E . The explanation is the same as the explanation given in question number 10. Left with a choice between B and E we can see the point charges in diagram E leave one point charge and enter the other point charge. That type of electric field between two point charges is produced when two unlike charges are near each other. 13. The correct answer is A . In the Carnot cycle the heat is added between A B. 14. The correct answer is C . The release gas or exhaust occurs between C D in the diagram. Answers to Part B Questions 15-75 15. The correct answer is A . Due to the mass that is converted in the nucleus mass defect to hold the protons together in the nucleus the proton does not have the same mass when it is inside the nucleus as it has outside the nucleus. The hydrogen proton is the proton that is least affected because it is the only proton in the hydrogen atom. 16. The correct answer is B . The total resistance for a set of resistors in parallel is found by using the sum of the reciprocals. I-I4-I4- That is to do the following R - R R R R yielding the decimal solution -1 .05 .025 .0167 .0124. Which is R 1 .1042 . R 17. The correct answer is E . Work is defined as a force applied through a distance. The weight lifter did not move the weights through any distance after he lifted them overhead. He just stood holding the weights overhead which does not meet the meaning of work in a physics sense. Peterson s 295 PRACTICE IESI 2 18. The correct answer is D . Power is the rate at which work is done Power ----. The weight lifter lifted the weights up from time the floor to a distance
