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.

The lower portion of the rope pulls down on the higher portions of the rope. Therefore, the tension in the rope increases as we move up the rope.What is the period of a wave if the wavelength is 100m and the speed is 200 m/s? ... Just like sound wave travels at a constant 340.29m/s in air, it does not change regardless.

a high pressure system is a dense air mass that is usually cooler and drier than the surrounding air. a low pressure system is a less dense air mass that is usually wetter and warmer than the surrounding air.

in general, areas that experience high atmospheric pressure also experience fair weather. low pressure systems can cause the formation of clouds and storms. air usually flows from areas of high pressure to areas of low pressure..
