Answer:
Farming
Explanation:
There were three droughts in the 1930s.
Farmers had deep plowed the land and killed the native grasses that trapped soil and moisture.
During the droughts, the moisture evaporated, and the loose soil turned to dust.
The mass of the seashell suspended by the two strands of spider silk is 0.28 kg.
The given parameters:
- <em>Tension on each strand of silk, T = 1.42 N</em>
- <em>Angle of inclination of each strand, θ = 75⁰</em>
The mass of the seashell at equilibrium is calculated by applying Newton's second law of motion;
where;
- W is the weight of the seashell
The weight of the seashell is calculated as;
The mass of the seashell is calculated as follows;
Thus, the mass of the seashell suspended by the two strands of spider silk is 0.28 kg.
