In a stadium, fans stand up and sit down to produce a wave across the stadium. this type of wave where the material travels perpendicular to the direction of travel of the the wave. which type of wave does this describe? a) mechanical wave. b) transverse wave. c) longitudinal wave. eliminate d) electromagnetic wave.

Which type of basaltic lava flow has a fairly smooth

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

Aforklift raises a box above the floor and does 2,000 j of work. if the forklift motor consumes 3,000 j of electrical energy from the battery to raise the box, what is the efficiency of the lift?
