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 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.
