An ionized nitrogen molecule (N2+) at point A has charge +e and moves at 1.68 ✕ 103 m/s in the positive x-direction. A constant electric force in the negative x-direction slows the molecule to a stop at point B, a distance of 0.841 mm past A on the x-axis. Calculate the x-component of the electric field and the potential difference between points A and B. (The mass of a nitrogen molecule is 4.65 ✕ 10−26 kg and the fundamental charge is e = 1.60 ✕ 10−19 C.)

firearm identification is the process of analyzing the bullets and cartridge cases left at a crime scene to determine if they came from a particular firearm. marks on the bullets and cartridges may be common to every firearm of that type. these are called class characteristics.

jupiter is the largest planet in our solar system, having a mass and radius that are respectively, 318 and 11.2 times that of earth. suppose that an object falls from rest near the surface of each planet and that the acceleration due to gravity remains constant during the fall. each object falls the same distance before striking the ground. determine the ratio of the time of fall on jupiter to that on earth.
