Curve A:
IV characteristics of an ohmic device

Curve B:

Curve C:

Curve D:

Curve E:
This curve appears to be the integral of a sinusoid. It could therefore represent the total electrical power dissipated as a function of time for a device through which we pass an alternating current

Curve F:
This curve could represent the amplitude of oscillation of an undammed spring which is the suddenly stopped.

Curve G:
This curve could represent the magnitude of a pendulums displacement from its equilibrium position (assuming the pendulum begins at maximum displacement).

Curve H:
Charging of a capacitor

Curve I:
Radioactive decay. This curve could represent the number of nuclei decaying per second from some radioactive source.

Curve J:
Normal distribution: Height or weight
This could also be a resonance curve. The Y axis could be the amplitude of osciallation and the X axis could represent the frequency of the input, at the natural frequency we would get a very high amplitude response.

Curve K:


Curve L:
This curve could represent the fracture toughness of an alloyed metal, the Y axis representing the fracture toughness and the x - axis representing the volume fraction of the alloy.
