5.35 blocks a and b are identical and each have a mass of 10 kg. block b is at rest when it is hit by block a which is moving with velocity va-6 m/s just before impact. blocks a and b stick together after the impact, and you may neglect friction during the impact. after the impact, the velocity of blocks a and b decreases due to friction. the coefficient of kinetic friction between all surfaces is -0.20. (a) determine the velocity of block a and b immediately after a hits b. (b) determine the impulse of the force of block a on block b during the impact. (c) determine the time required for the velocity of the blocks to drop to 1 m/s (d) determine the distance traveled by the blocks during this time interval. before the impact after the impact, blocks a and b travel together. 6 m/s

Which statement is true for light passing into a medium that is more optically dense than the first medium through which it past

Since the investigative question has two variables, you need to focus on each one separately. thinking only about the first part of the question, mass, what might be a hypothesis that would illustrate the relationship between mass and kinetic energy? use the format of "if…then…because…” when writing your hypothesis.

Dinate system, and a charge q = - 2.00 nc is placed s2 10 n> c. (a) what is the change in electric potential energy when the dipole moment of a molecule changes its orientation with respect to es from parallel to perpendicular? (b) at what absolute temperature t is the average translational kinetic energy 32 kt of a molecule equal to the change in potential energy calculated in part(: abovethistemperature, thermalagitationprevents the dipoles from aligning with the electric field.) placed in a uniform electric field e with magnitude 1.6 * 6 on the positive x-axis at x = 4.00 cm. (a) if a third charge q3 = +6.00 nc is now placed at the point x = 4.00 cm, y = 3.00 cm, find the x- and y-components of the total force exerted on this charge by the other two. (b) find the magnitude and direction of figure p21.62 ll uu 21.55 . torque on a dipole. an electric dipole with dipole moment ps is in a uniform external electric field es. (a) find the orientations of the dipole for which the torque on the dipole is zero. (b) which of the orientations in part (a) is stable, and which is unstable? (hint: consider a small rotation away from the equi- librium position and see what happens.) (c) show that for the stable orientation in part (b), the dipole’s own electric field tends to oppose the external field. 21.62 ..
