The duck always creates oscillations in the water with a frequency of 2.0 Hz. Under what conditions for wave speed and boat velocity will the wavelength of waves generated by the duck be 2.5 m and
the wavelength of waves observed by the man in the boat be 1.9 m? (Adjust all three sliders to achieve
the conditions above. Assume that the duck is moving rightward with a positive velocity).

High schoolphysics 5+3 pts a neon light consists of a glass tube with metal wires at each end. when connected to a high-voltage source, the gas glows. if a fly lands on the glass tube, what will most likely happen? a) the fly will not feel a shock because the glass conducts any free electrons back into the gas. b) electrons will flow directly from the metal wires along the glass and shock the fly. c) the fly will not feel a shock because the glass insulates it from the electrons in the gas and the metal. d) electrons that are moving through the gas will be conducted through the glass and shock the fly.

If 2 moles of co_2 at 2l and 500k are expanded reversibly to 20l, more work can be obtained from an adiabatic process than from an isothermal process. is the above statement true or false?
