A string with a linear density of 6 kg/m is stretched to a length of 0.9 meters and fastened at both end so that it can freely vibrate. The tension on the string is 1100 Newtons. At what speed would a wave propagate on this string

Air conditioners not only cool air, but dry it as well. suppose that a room in a home measures 5.0m×9.0m×2.4m . if the outdoor temperature is 30 ∘c and the vapor pressure of water in the air is 85 % of the vapor pressure of water at this temperature, what mass of water must be removed from the air each time the volume of air in the room is cycled through the air conditioner? the vapor pressure for water at 30 ∘c is 31.8 torr.
