A hand holding a rope moves up and down to create a transverse wave on the rope. The hand completes an oscillation in 1.2 s, and the wave travels along the string at 0.8 m/s. The amplitude of the wave is 0.1 m. a.) Find the frequency at which the crests pass a given point in space.

show the wavelengths of a wave. show the crests of a wave.

when two balls of the different masses are dropped from equal height, they reach the ground at the same time .this is because they experience the same acceleration.

the acceleration is independent of mass.

thus when they are dropped they will always maintain the same velocity and travel the same distance (neglect air resistance of course) at the same time.

myth. it was once thought that animals, including cats and dogs, could only see in black and white. however, scientists have proven this to be a myth. in all animals, including humans, the perception of colour is determined by the presence of cells in the eye called cone photoreceptors.
