You adjust the frequency of the rf oscillator on the nmr electronics until there is negligible beating between the oscillator and the spin precessions, yielding equal frequencies of f= 15.30 mhz. the static magnetic field from the rare-earth magnet is:

Two masses are connected by a rope that hangs over a pulley as shown below. the pulley is a uniform cylinder of radius 푅=0.381meters and mass 푀=3.1푘푔. initially 푚"is on the ground and 푚#rests 2.5 meters above the ground. if the system is released, use conservation of energy to determine the speed of 푚#just before it strikes the ground. assume the pulley bearing is frictionless.

You can estimate the degree to which a bond between two atoms is ionic or covalent by calculating the

Is a volume of space that is empty of matter.
