Magnetic resonance imaging instruments use very large magnets that consist of many turns of superconducting wire. a typical such magnet has an inductance of 40 h. when the magnet is initially powered up, the current through it must be increased slowly so as not to "quench" the wires out of their superconducting state. one such magnet is specified to have its current increased from 0 a to 150 a over 220 min.

what constant voltage needs to be applied to yield this rate?

i was thinking more like reflects green light, just not sure

the focus of lesson 1 is newton's first law of motion - sometimes referred to as the law of inertia. newton's first law of motion is often stated as. an object at rest stays at rest and an object in motion stays in motion with the same speed and in the same direction unless acted upon by an unbalanced force.

explanation:

kepler used the data from tycho blahe (his mentor) to construct the laws of planetary motion.

measure their densities same density, same sub
