A composite pulse (or pulse sandwich) is an older method utilized to correct pulse imperfections due to not setting proper pulse durations or angles. For example an 180y pulse can be replaced by the 90y-180x-90y pulse sandwich a) Utilize the vector model to show this pictorially (both the single pulse and the pulse sandwich). Include where the pulses are applied and where the magnetization ends at the end of the pulse sandwich.
A photon has an energy E and wavelength (lamda) before scattering from a free-rest electron. FInd the initial wavelength and the initial energy of photon
In a mass spectrometer, a singly, negative charged ion having a particular velocity selected by using a magnetic field of .10 T perpendicular to an electric field of 1000 V/m. What is the mass of the ion
A 5.00 x 10^4 kg space probe is travelling at a speed of 14000 m/s through deep space. Retrorockets are fired along the line of motion to decrease the probe's speed. The retrorockets generate a force of 4.00 x 10^5 N over a distance of 2600 km. What ..
