The frequency f in waves per second and the wavelength w in meters of a sound traveling in air are related by the equation f w equals 343 where 343 meters per second is the speed of sound in air calculate the wavelength of a musical note with a frequency of 200 waves per second

Beryl states that insulation with the smallest possible thermal conductivity is best to keep a house warm in winter, but worst for keeping a house cool in summer. sapphire insists the reverse is true: low thermal conductivity is good in the summer, but bad in the winter. which one, if either is correct? a. beryl, because low thermal conductivity results in low heat transfer. b. beryl, because low thermal conductivity results in high heat transfer. d. sapphire, because low thermal conductivity results in high heat transfer. e. neither, because low heat transfer is desirable both in summer and in winter.
