2. A barometer is carried up on a balloon. Why does the reading on the barometer fall?

3. Objects of different weights are placed on a rigid, horizontal surface.

Which row shows the correct pressure acting on the surface?

Weight (N) Area in contact ($m^{2}$) Pressure (Pa)
A 10 0.1 1
B 20 0.2 0.01
C 30 0.1 300
D 40 0.2 8

4. The diagrams show, to the same scale, the vertical sections of a set of circular vessels, each containing the same depth of water.

• idk either

2. how can i get the answers….

3. I think here, in question 9 the answer (a) shall be
5.0 x 10^-3
5.0 x 10^3

• Can you show how you arrive at $5.0 \times 10^{-3}$?

• its 5.0 x 10^4

4. physics

• same bro
