A protocol for desalting oligonucleotide solutions specifies centrifugation of a 1,250 uL aliquot of solution at 3300 X g for 30 min. The rotor in your centrifuge has a maximum radius of 4.8 cm. What rpm should you use to centrifuge the solutions? Answer to the nearest whole number.

Atoaster oven has a resistive heating element. the average rate at which it dissipates energy as thermal energy is 1.00 \(\rm kw\). in the united states, emf amplitude in household circuits is \(\mathcal e_{\max}\) = 170 \({\rm \; v}\) and the \(\rm ac\) oscillation rate is 60 \(\rm hz\). part a what is the root-mean-square current through the heating element?
