Literary and artistic naturalism aims at accuracy and objectivity and cultivates realistic and even sordid portrayals of people and their environment. Philosophical naturalism, which is often identified with materialism, holds that minds, spirits, and ideas are fundamentally material.
For the stiffness to weight ratio, see specific modulus. The specific strength is a material's strength (force per unit area at failure) divided by its density. It is also known as the strength-to-weight ratio or strength/weight ratio. In fiber or textile applications, tenacity is the usual measure of specific strength. The SI unit for specific strength is Pa /(kg / m 3), or N Â·m/kg, which is dimensionally equivalent to m 2 /s 2, though the latter form is rarely used.
Total Price (y) 20 40 60 80 100 Total Pound (x) 2 4 6 8 10 Ratio (K) 1:10 (for all) The ratio is constant (k = 10), so the relationship can be described by the equation y = 10 x. This equation means that the total number of price is always 10 times the number of pound. So the constant of proportionality is 10.
