What happens when the temperature of the medium that sound is passing through increases?

You shoot a beam of electrons through a double slit to make an interference pattern. after noting the properties of the pattern, you then double the speed of the electrons. what effect would this have?

Constructive interference in a standing wave occurs at the wave's nodes. True False

Scientific evidence documents the pattern of evolution. The evidence exists in a variety of categories. What are these categories?

How does the speed of a wave relate to its wavelength and frequency

Josh rolled a bowling ball down a lane in 2.5 seconds. The ball travelled at a constant acceleration of 1.8 m/s/s down the lane and was traveling at a speed of 7.6 m/s by the time it reached the pins at the end of the lane.

How many meters of the rock wall eroded between 1910 and 1927?

As air temperatures increase, evaporation increases. Warmer temperatures also increase the capacity to absorb water vapor. More water vapor in the atmosphere accelerates the greenhouse effect.

What is the speed of a 50 g rock if its de Broglie wavelength is 3.32 x 10?
