Polarizing: an electron and a neutral carbon atom are initially 1x10-6 m apart (about 10,000 atomic diameters), and no other particles are in the vicinity. the polarizability of a carbon atom has been measured to be a 1.96x10-40 c-m/(n/c). for all parts of this problem, derive an entirely symbolic answer in terms of variables such as a, e, and the distance d before plugging in numerical values to get a numerical answer a) calculate the electric field created at the atom's location due to the electron. b) calculate the dipole moment induced in the atom due to the electron's presence. c) calculate the electric field created at the electron's location due to the polarized atom. d) calculate the force exerted on the electron by the polarized atom. e) calculate the initial magnitude and direction of the acceleration of the electrorn. f if the electron and carbon atom were initially twice as far apart, how much smaller would the initial acceleration of the electron be?

These models show the electron structures of two different nonmetal elements. which element is likely more reactive, and why? element 1 is more reactive because it has fewer electron shells and is toward the top of its group on the periodic table. element 1 is more reactive because it has more electrons in its valence shell and is farther to the right on the periodic table. element 2 is more reactive because it does not have a valence shell close to the nucleus, so it will attract electrons. element 2 is more reactive because it does not have a full valence shell, so it will attract electrons.

The ballistic pendulum was invented in 1742 by english mathematician benjamin robins. it consists of an initially stationary pendulum that moves after being struck by a bullet, and it is used to measure the original velocity of the bullet. the known variables are the bullet's mass m, the pendulum's mass m, and the height to which the block and bullet swing, determined by the length of the pendulum l and final angle θ. two principles of physics are necessary to solve for the bullet's original velocity. what are these principles? conservation of momentum and newton's third law conservation of energy and conservation of angular momentum grade summary deductions 0% potential 100% conservation of momentum and newton's second law. newton's second law and conservation of angular momentum. conservation of energy and newton's third law conservation of momentum and conservation of angular momentum. conservation of momentum and conservation of energy conservation of energy and newton's second law.
