An active heat sync will keep a computer cool and basically cool the CPU and processors. A passive heat sink will only cool the CPU and whatever else it needs to cool when the CPU actually NEEDS to be cooled. I am not sure if this is all correct but I know about basic heat syncs and from my understanding this is right.
Calculate LER for a rectangular wing with a span of 0.225m and a chord of 0.045m. The weight of the glider is 0.0500 Newtons. (Note: the wing span is the width of the wing and is measured from wing tip to wing tip, or perpendicular to the fuselage. The wing chord is the length of the wing measured parallel or along the length of the fuselage.)
Answer:
Area of rectangular wing = span × chord = 0.225×0.045= 0.010125m2
LER = Area/weight = 0.010125/0.0500 = 0.2025
