You are working with a 3 T MRI scanner with maximum gradient strength of 40 mT/m in all 3 axes (x,y,z). Your acquisition uses maximum gradient strength to minimize the duration of the data acquisition window. When the Gx is the only gradient that is turned on, what is the rotation frequency for spins located at x=5cm, y=5cm? The gyromagnetic ratio is γ=42.576 MHz/T

1. An electron moves in a circular path in the magnetic field of an electromagnet. The plune of the electron's Sicular path is parallel to the smooth vole faces of the electromagnet. In the region where the electron is moving the magnetic field is uniform and has magnitude 0,50 T. The electron moves with a speed of 1.5 x 10 m/s. a. If someone could observe the electron from the north pole of the electromagnet, would the electron inove clockwise...

Working with lists
Background
This project addresses playing music. A song consists of notes,
each of which has a length (duration) and pitch. The pitch of a
note is described with a letter ranging from A to G. 7
notes is not enough to play very interesting music, so there are
multiple octaves; after we reach...
