Assume the same dimensions and the material as in (2), if there is a pressure source at the top opening of the tube, plot the pressure response(both amplitude and phase)at the bottom opening of the tubeas a function of frequency from 1Hz to 300Hz.(Neglect the length of the tube. Usematlab oranyother tools for the plot.)

The boat's velocity relative to the riverbank can be resolved into two components. the component going north is 2.7 m/s and the component going west is 1.2 m/s.we add these two vectors and then find the magnitude of the resultant to get the speed.the magnitude of the resultant vector from adding can be obtained by the pythagorean theorem.    to two significant figures, the boat's speed relative to the riverbank is 3.0 m/s.

We can infer that star y is closer but other factors must be considered include the heat of the star, the mass, and the brightness of the star. even though star x seems dimmer it may just be less bright or contains less heat.
