You can use Newton's Universal Law of Gravitation to write a formula to approximate the mass of the Earth. The formula for e, the mass of the Earth in kilograms is, e=fr^2g^-1 where f is the force, r is the radius of the Earth, and g is the gravitational constant. f,r and g have the numerical values f=9.8, r=6.37x10^6, and g=6.67x10^-11. Rewrite the value of r in standard form. Rewrite the value of g in standard form.
