A harmonic wave is traveling along a rope. It is observed that the oscillator that generates
the wave completes 38 vibrations in 33.8 s.
Also, a given maximum travels 443 cm along
the rope in 10.7 s.
What is the wavelength?
Answer in units of cm.

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.
