Q. Light is emitted by a sodium sample that is moving toward Earth with speed v. The wavelength of the light is 589 nm in the rest frame of the sample. The wavelength measured in the frame of Earth is 537 nm. Find v.

Q. At one point in a pipeline, the water's speed is 3.00 {rm m}/{rm s} and the gauge pressure is 4.00×104 {rm Pa}. Find the gauge pressure at a second point in the line 11.0 {rm m} lower than the first if the pipe diameter at the second point is twice that at the first.
