An ideal spring of negligible mass is 11.00 cm long when nothing is attached to it. When you hang a 3.10-kg weight from it, you measure its length to be 12.40 cm . Part A If you wanted to store 10.0 J of potential energy in this spring, what would be its total length

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?
