Step-by-step explanation:

Mass of the wooden block, m=5kg

Thrust due to wooden block,

Mg=5kg×9.8ms

−2

=49N

(a) Surface area of 20cm×10cm surface,

A=(20×10)cm

2

=(0.2×0.1)m

(b) Surface area of 40cm×20cm surface,

A=(40×20)cm

2

=(0.4×0.2)m

Answer:

Physical weathering is caused by the effects of changing temperature on rocks, causing the rock to break apart. The process is sometimes assisted by water.
