What is a fluid?

A liquid or a gas

1 of 5

How does density effect pressure?

A higher density makes the pressure higher as the particles are closer together

2 of 5

A cylinder has three spouts above one another, out of which one would the water spurt the furthest?

The bottom one as there is a higher pressure due to more water being above it so there being a bigger force.

3 of 5

How does atmospheric pressure change with height?

Atmospheric pressure decreases with increased altitude. This is because there is less air above to push down, decreasing the density as there are less particles per square centimetre. On earth g.f.s is constant so won't affect the density.

What are the typical values of a person walking, running and cycling in m/s, and what is the speed of sound in m/s?

Walking~1.5m/s Running~3m/s ~Cycling~6m/s ~Speed of sound=330m/s
