A long rope with mass m is suspended from the ceiling and hangs vertically. A wave pulse is produced at the lower end of the rope, and the pulse travels up the rope. Does the speed of the wave pulse change as it moves up the rope, and if so, does it increase or decrease? Explain

What is physics Physics is the study of fundamental laws of nature. These laws can be expressed as mathematical equations. These laws can appear quite simple, but much complexity can arise from them. In physics we use the SI system for unit labeling Length is measured in meters (m) Mass is measured in kilograms (kg) Time is measured in seconds (s) Length is standardized using the distance traveled by light in a vacuum in 1/299,792,458 of a second Some typical lengths (to 1 significant figure): Diameter of our Galaxy: 8 x 10 2m Radius of the Earth: 6 x 10 6m Length of a Football Field: 1 x 102m Diameter of a CD: 1 x 10 -1m Diameter of a hydrogen atom: 1 x 10 -m0 Diameter of an electron: 3 x 10 -1m One kilogram
