Statement 1: All

Statement 2:None

Statement 3: Curves 2 and 3

Statement 4: Curves 4 and 5

Statement 5: Curve 2

Statement 6: Curve 2, 3, 4 and 6

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.
