You and your lab partner are each holding an end of a slinky Your lab partner is sending waves through the slinky at a particular
frequency. Your partner then doubles the frequency at which they are
making the waves. What happens to the wavelength of the waves as a
result? *
the wavelength doubles
the wavelength is half as much
there is no way to determine what happens to the wavelength
O
the wavelength stays the same

Arigid tank is divided into two equal parts by a partition. one part of the tank contains 3 kg of compressed liquid water at 400 kpa and 60°c while the other part is evacuated. the partition is now removed, and the water expands to fill the entire tank. determine the entropy change of water during this process, if the final pressure in the tank is 40 kpa. use steam tables.
