Differences in air temperature are caused by differences in the energy of the molecules that make up the air.

State one advantage and one disadvantage of using a plane mirrior as a driving mirrior

Find v(t), given acceleration a(t)=7j and initial velocity v(0)=k

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?
