You are holding a plane mirror 1 meter in front of your eyes and are able to see a 15 meter tall tree behind you. The image completely fills your 25 cm tall mirror. How far away from the tree are you standing?

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?
