The Table shows information about four people walking on soft snow, each wearing different footwear.
Table
| Footwear | Weight of person in N\text{N}N | Area in contact with snow in m2\text{m}^{2}m2 | Pressure on snow in Pa\text{Pa}Pa |
|---|---|---|---|
| walking boots | 600 | 0.050 | 12 00012\,00012000 |
| snowshoes | 600 | 0.30 | |
| high-heeled shoes | 600 | 0.012 | |
| skis | 720 | 0.36 |
Complete the Table.
The greater the pressure on the snow, the further a person sinks into the snow.
Give the footwear that would make the person sink furthest into the snow.
The person wearing skis has a greater weight than the person wearing snowshoes.
Explain why both people exert the same pressure on the snow.
