Suppose two comets, comet a and comet b, were orbiting the sun, having the same average orbital radii. if comet a had a higher orbital eccentricity than comet b, which comet would, during some portion of its orbit, have the lower orbital speed? a. a b. b c. both would be the same d. impossible to tell

Acombination reaction is when two or more combine to form one product. a decomposition reaction is when a substance breaks down into two or more simpler substances in a chemical reaction.

At a certain instant after jumping from the airplane a, a skydiver b is in the position shown and has reached a terminal (constant) speed vb = 52 m/s. the airplane has the same constant speed va = 52 m/s, and after a period of level flight is just beginning to follow the circular path shown of radius ρa = 2330 m. (a) determine the velocity and acceleration of the airplane relative to the skydiver. (b) determine the time rate of change of the speed vr of the airplane and the radius of curvature ρr of its path, both as observed by the nonrotating skydiver.

Can a molecule have bond dipoles but not have a molecular dipole?
