The 200-mm test tube also contained some water (besides the metal) that was subsequently added to the calorimeter (in part a. considering a higher specific heat for water, will the temperature change in the calorimeter be higher, lower, or unaffected by this technique error?

50.)the diagram below represents the wave fronts produced by a point source moving to the right in a uniformmedium. observers are located at points a and b.compared to the wave frequency and wavelength observed at point a, the wave observed at point b has a(1) higher frequency and a shorter wavelength(2) higher frequency and a longer wavelength(3) lower frequency and a shorter wavelength(4) lower frequency and a longer wavelength
