For each of the following systems and time intervals, select the appropriate version of δk + δu + δeint = w + q + tmw + tet + ter, the conservation of energy equation. (a) the heating coils in your toaster during the first five seconds after you turn the toaster on δeint = q + tet + ter δk + δu + δeint = w + q + tmw + tmt δu = q + tmt 0 = q + tmt + tet + ter δk = w + q δeint = w + q + tet δu = w + q + tmw + tmt (b) your automobile from just before you fill it with gas until you pull away from the gas station at speed v δeint = q + tet + ter δk + δu + δeint = w + q + tmw + tmt δu = q + tmt 0 = q + tmt + tet + ter δk = w + q δeint = w + q + tet δu = w + q + tmw + tmt (c) your body while you sit quietly and eat a peanut butter and jelly sandwich for lunch δeint = q + tet + ter δk + δu + δeint = w + q + tmw + tmt δu = q + tmt 0 = q + tmt + tet + ter δk = w + q δeint = w + q + tet δu = w + q + tmw + tmt (d) your home during five minutes of a sunny afternoon while the temperature in the home remains fixed δeint = q + tet + ter δk + δu + δeint = w + q + tmw + tmt δu = q + tmt 0 = q + tmt + tet + ter δk = w + q δeint = w + q + tet δu = w + q + tmw + tmt
