Fat is what causes body fat, as this is stored energy. True False

True

Explanation:

The muscles, lungs and heart pick up these fatty acids, break them apart, and use the energy stored in the bonds to execute their activities.

The required length of the wire is 15.637 m

The power dissipated is 1,216 W

Explanation:

Length (L) = resistance×area/resistivity

Resistance = 19 ohm

Area = 0.001276 in^2 = 0.001276in^2 × (2.54cm/1in)^2 = 8.23×10^-3 cm^2

Resistivity = 1×10^-4 ohm-cm

L = 19×8.23×10^-3/1×10^-4 = 1563.7 cm = 1563.7/100 = 15.637 m

Power = I^2 R = 8^2 × 19 = 64×19 = 1,216 W
