Explain how the use of heavy machinery in an area can lead to an increase in the severity of flooding.

Soil compaction results from human activities that press down on soil and eliminate much of the pore space between soil particles. This compaction and the loss of pore space reduces the soil’s ability to store water meaning that less water is absorbed by the soil when it rains. Instead the water flows as runoff, increasing the severity of flooding and erosion in the area

weight of the box is given as

here this is placed on the inclined of angle 42 degree

now this weight will have two components one is along the incline other is perpendicular to it

so here we need to apply a force parallel to incline opposite to its component of weight

so here the component of weight is given as

here we have

so it requires 75 n force to move it upwards
