Physics Final Exam revision b 11/7/14
Directions: It is important that you provide answers in your own words. Please focus only on information from the text/eBook to create your own solutions. Please do not use direct information from an outside source (especially copying and pasting from an “answer” website). Use of direct information from an outside source is against school policy. All answers will be checked for plagiarism. Instances of plagiarism can result in probation or possible dismissal from the school.
Grading: Please be sure to follow all guidelines (number of sentences/showing all calculations) and to provide the correct metric units of measure. It is important for you to observe the number of sentences, when required. This helps me assure the integrity of your responses. All questions are 5 points (1 point for sentence number /correct units).
1. Consider eight two-cubic centimeter (2 cm3) sugar cubes stacked so that they form a single 2 x 2 x 2 cube. How does the surface area of the single, large cube compare to the total surface area of the individual eight cubes? Report your answer as a ratio. Be sure to show all calculations leading to an answer.
2. A rectangular barge 6 m long and 3 m wide floats in fresh water. How much will the barge sink when loaded with 600 kg of sand? Show all calculations leading to an answer.
3. When a steadily-flowing gas flows from a larger-diameter pipe to a smaller-diameter pipe, what happens to each of the following? (I pt ea)
a. The density of the gas
b. The speed of the gas
c. The pressure of the gas
d. The temperature of the gas
e. The kinetic energy of the gas
4. When a 3-kg glass jar containing 3 kg of water is removed from the refrigerator, which material (if either) absorbs more heat from the room? Support your answer using 3 – 4 complete sentences.
5. In a lab experiment, a 0.6-g peanut is burned beneath 60 g of water. Heat from the burning peanut raises the water temperature
