You have two forces, 109.2 N and 72 N. What is their resultant (magnitude) if the
first acts upward and the second acts downward?
Answer in units of N.

Use the right-hand rule for magnetic force to determine the charge on the moving particle. this is a charge.

The energy equivalent of the rest mass of an electron is

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?
