A projectile is hammered into a block lying on a horizontal block to an area equal to 0.7 block. There is no friction between the pad and the surface. Calculate the amount of heat released

Iwill give brainliest if you answer right : )

Convection currents are caused by differences in what two things?

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?
