You work for a company that specializes in electron beam-impact deposition. This apparatus uses a tightly focused electron beam to deposit atoms on a surface with very fine spatial resolution. You are given the job of calculating the maximum possible deflection of the electron beam when the random magnetic fields in the laboratory are reduced (by shielding) to a maximum value of 0.15 mGauss. The electrons are accelerated from rest through 20 kV and the path length is 3.6 cm. If the magnetic fields were later discovered to be twice as large, what modified path length would yield the same deflection as you originally calculated

When a spring is compressed, the energy changes from kinetic to potential. which best describes what is causing this change? work power gravitational energy chemical energy

The ultracentrifuge is an important tool for separating and analyzing proteins. because of the enormous centripetal accelerations, the centrifuge must be carefully balanced, with each sample matched by a sample of identical mass on the opposite side. any difference in the masses of opposing samples creates a net force on the shaft of the rotor, potentially leading to a catastrophic failure of the apparatus. suppose a scientist makes a slight error in sample preparation and one sample has a mass 10 mg larger than the opposing sample. if the samples are 12 cm from the axis of the rotor and the ultracentrifuge spins at 70,000 rpm, what is the magnitude of the net force on the rotor due to the unbalanced samples? ( be thorough on your answer)
