The density of water is 1. © 2012 The College Board. © 2012 The College Board. A glass tube is fitted with a movable piston that allows the indicated length L to be adjusted. Clearly indicate what quantities you would measure and with what instrument each measurement would be made. Web or Mass distribution prohibited. Anon, I'll first answer your question that I think the difficulty was dead-on normal overall.
The slope of the hill is inclined at an angle of 15° with the horizontal as shown in the figure above. Justify your answer using your results from parts b and c. For any isolated electric charge, the electric potential is defined as zero at an infinite distance from the charge. As a result, questions and the order in which they appear will differ each time a new test window is opened. Relativistic effects can be ignored throughout this question.
A sine-wave generator with an adjustable frequency is connected to a speaker near the open end of the tube. For each incorrect vector, a point was deducted, with the minimum possible score being 0. Start Learning Now Our free lessons will get you started required. Darren, you're right that I calculated through X. The proton reaches a distance D from the center of the nucleus and then reverses direction. Indicate one quantity that can be varied, and describe how a graph of the resulting data could be used to determine the speed of sound.
Everything else was on target, so the overall difficulty was standard. Using the menu at the top, select a resource. You will then have the option of selecting resources within the section or going directly to a specific chapter. Be sure to write all your answers to the questions in the space provided. The mercury is at the same height on both sides of the new tube as it was in the U-tube, as shown by the dashed line.
Clearly identify independent and dependent variables, and indicate how the slope of the graph relates to the speed of sound. Visit the College Board on the Web: www. In terms of velocity and acceleration, describe the motion of the sled as it travels on the horizontal ground. All other products and services may be trademarks of their respective owners. Determine the average potential energy change of an electron as it moves from point Z to point X.
Indicate on the diagram the direction of the current through point Y. And in case you need more help with specific topics, our own time-saving video course will answer all your questions. Show all your work in this booklet in the spaces provided after each part. The College Entrance Examination Board was not involved in the production of and does not endorse this product. Gardner will add you as quickly as he can.
It is to your advantage to do this, because you may earn partial credit if you do and you will receive little or no credit if you do not. Visit the College Board on the Web: www. As shown in the figure above, a 24. The same volumes of oil and water that were in the U-tube are now poured into the new tube, on the left and right respectively. © 2012 The College Board.
Clearly indicate with the symbol tl the time at which the sled leaves the slope. After equilibrium is reached, the lock is removed so the piston is free to move. Unless otherwise stated, the frame of reference of any problem is assumed to be inertial. If the free response section is harder than usual, then a lower total score will be necessary to earn each grade; similarly, an easy free response drives the scores for each grade up. Founded in 1900, the College Board was created to expand access to higher education. Indicate whether the mass of the nucleus is greater or less than the mass of the fission products.
Use the curriculum framework to determine the specific concepts for each individual course. The cylinder contains a fixed amount of an ideal gas that is initially at room temperature and atmospheric pressure. The output of a microphone at the open end is connected to a waveform display. Block B of mass 1. Any other type of reproduction of these materials is strictly prohibited. Visit the College Board on the Web: www.
