The speed of sound through argon is shown. A 3 column by 3 row table. Column 1 is titled Element and includes the following entries: Argon (gas), Argon (liquid). Column 2 is titled Temperature (degrees Celsius) and includes the following entries: 27, negative 1.86. Column 3 is titled Speed of Sound (meters per second) and includes the following entries: 323, 813.
If argon could exist as a solid, what would best represent the speed through solid argon?

10 m/s
250 m/s
500 m/s
3200 m/s

This problem has been solved! see the answera non-uniform fire escape ladder is 6.0m long whenextended to the icy alley below. it is held at the top by africtionless pivot, and there is neglibible frictional force fromthe icy surface at the bottom. the ladder weighs 250n, and it'scenter of gravity is 2.0m along the ladder from the bottom. amother and child of total weight 750n are on the ladder 1.5m fromthe pivot. the ladder makes an angle θ with the horizontal.find the magnitude and direction ofa) the force exerted by the icy alley on the ladderb) the force exerted by the ladder on the pivotc) do your answers in part a and b depend on the angle?
