A) How much force would be required to start a 1.25-kg object sliding along a horizontal surface if the coefficient of kinetic friction is 0.17 and the coefficient of static friction is 0.20? μK=0.17, μS= 0.20 b) If the force that was applied remained the same as in part a), what would be the acceleration of the object after it started to move?

Although longitudinal waves can travel through all media types what is the disadvantage of this type of wave transmission? a) he efficiency of he wave transmission is greatly diminished as the media becomes less dense b) the oscillation of one set of particles has a huge impact on neighboring particles c) particles become too close together as they bump into each other making it more likely to hit other particles down the line
