The unit of pressure is:

1. N x m
2. kgf
3. N m^-2
4. kgf m²

The pressure and thrust are related as:

1. Pressure = Thrust
2. Pressure = Thrust x Area
3. Pressure = $\dfrac{\text{Thrust}}{\text{Area}}$
4. Pressure = $\dfrac{\text{Area}}{\text{Thrust}}$

The feet of lizards act like:

1. moving pads
2. drilling pads
3. suction pads

Pressure exerted by a liquid is due to its:
