The charged particles in the beams that thomson studied came from atoms. as these particles moved away from their original atoms, they formed a visible beam. the current model of the atom includes protons, neutrons, and electrons.

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?
