Explanation:
Let acceleration due to Gravity for a planet is given by:

Here,
Escape velocity is given by:

Here,
and g_X = 2g
Therefore,
Soil is the result of chemical or physical weathering of a parent rock .this is so since the soil is just tiny particle of the huge parent rock and hence it affects soil composition<span> .</span> if the parent rock was made of limestone then the soil composition will constitute calcite<span> and </span><span>aragonite mineral elements from the limestone parent rock.</span>
Wavelength = 1/frequency thus wavelength =1/30000
