Given the two charges 2. on the x-axis, as seen in the diagram below 16 c 36 c the 36c charge's position is fixed at x 0 m, and the 16c charge's position is fixed at x 10m. a charge, q -3 c, is placed at x,- 6.0 m, where the net force on it 0 n. a) [26.3) keeping the location of q, as x, what is the electric potential energy of the 3-particle system? b) (26.3] is the electric potential energy at xy a local minimum, a local maximum, or neither? justify the answer conceptually or mathematically c) [26.4] what is the electric potential at x (assuming the third charge is not there)?

Astudent is performing an experiment comparing sound and light waves. the student gathers the following data. what conclusion does the student most likely make based on this data? light waves always travel the same speed; however, the speed of sound is determined by the medium that it travels through. all sound waves always have the same energy, so the temperature of the medium does not affect wave speed. light needs to vibrate particles, so it travels fastest in tightly packed solids, while sound does not need a medium, so it travels fastest in a gas. tightly packed particles in solids slow down the light waves; however, sound waves make particles bounce into each other, so they travel faster in solids.

Under the action of a constant force an object accelerates at 7.8 m/s2. what will the acceleration be if (a) the force is halved? (b) the object's mass is halved? (c) the force and the object's mass are both halved? (d) the force is halved and the object's mass is doubled?
