Answer:
The soil plays an important part in the storage and distribution of the water that reaches it. The role the soil plays in the hydrological cycle is crucial for the maintenance of the biosphere, because it is provides water for plants, animals and humans.
M = 10kg
P = 40 kg.m/s
V= 4m/s
Formula v = p/m
V= p/m
=4okg.m/s / 10kg
=4m/s
