Carbonation, Hydrolysis and Oxidation all relates to chemical reactions with the rocks - so these are forms of Chemical weathering
Frost wedging is where the rocks and earth is broken apart by water freezing and turning to ice. It has nothing to do with rocks themselves changing in their chemical composition. So this is a type of physical weathering.

Answer:
<u>Frost wedging</u> is a type of physical weathering.
Answer:
2870 N
Explanation:
There are three forces on the mattress. Weight of the mattress, weight of the person, and buoyancy.
∑F = ma
B - mg - Mg = 0
Buoyancy is equal to the weight of the displaced fluid.
ρVg - mg - Mg = 0
ρV - m = M
Plugging in values:
M = (1000 kg/m³) (0.75 m × 2.25 m × 0.175 m) - 2 kg
M = 293 kg
The person's weight is therefore:
Mg = 293 kg × 9.8 m/s²
Mg = 2870 N
