Once you submit, you will no longer be able to change your answers. Are you sure you want to submit the quiz?
1.
The pressure difference between two points in a liquid depends on
The area of the container
The mass of the liquid
The vertical separation of the points
The width of the tube
2.
The pressure due to 10 m of water is about (g = 9.8)
1.0 × 102 Pa
1.0 × 103 Pa
1.0 × 107 Pa
9.8 × 104 Pa
3.
A graph of pressure against depth in a liquid is
A straight line with gradient ρg
A curve
A horizontal line
A line of gradient 1/ρg
4.
In the derivation, the area A cancels because
Pressure is area times force
Both the force and the weight are proportional to A
The area is small
The sides cancel
5.

1.0 × 106 Pa
1.0 × 104 Pa
1.0 × 105 Pa
7.6 × 102 Pa
6.
