A particular organic molecule forms an electric dipole by possessing an effective charge separation of 0.177 nm for a pair of ±1.60 × 10-19-C charges.
(a) What is the magnitude of the molecule\'s electric dipole moment?
(b) Find the magnitude of the torque that acts on the molecule when it is immersed in a uniform electric field of 4.87 × 105 N/C with its electric dipole vector at an angle of 25.3° from the direction of the field.
(c) Consider all possible angles between the electric field and the electric dipole vector. What is the greatest magnitude of torque that the electric field can exert on this molecule?
Two cars are traveling along a straight line in the same direction, the lead car at 25.2m/s and the other car at 31.0m/s. At the moment the cars are 41.9m apart, the lead driver applies the brakes, causing her car to have an acceleration of -2.07m..
