Question

Scaling laws are

a. general engineering guidelines for miniaturization
b. useful for estimating how the characteristics of something will vary with changes in characteristic dimension
c. helpful estimates of a device's performance at the nanoscale
d. accurate predictors of physical characteristics at the macro-, micro-, and nanoscales

Answer 1

Scaling laws are b. useful for estimating how the characteristics of something will vary with changes in characteristic dimension. For example, if a square is 4 inches in length and with (the characteristic dimensions), and that square is doubled in scale, that square will become 8 inches in length and width.
