A girl stands on a bathroom scale. In metric units, the scale indicates that her weight is 42 Newtons. This means the force of gravity is pulling her feet onto the scale with a force of 42

Newtons. With what force does the scale push back up against her feet?

Two people each hold the end of a rope and create waves by moving their arms up and down. this wave is best classified as a transverse wave because a) both the rope particles and the wave are moving in the same direction. b) the wave is moving up and down as the particles of the rope move horizontally. c) the wave is moving horizontally as the particles of the rope move up and down. eliminate d) the wave is moving in a parallel direction with the motion of the person's arms.
