Many people know that the weight of an object varies on different planets, but did you know that the weight of an object on earth also varies according to the elevation of the object? In particular, the weight of an object follows this equation: 2 - = Cr w , where C is a constant, and r is the distance that the object is from the center of the earth. a. Solve the equation 2 - = Cr w for r. W=C/r -2 the reciprocal makes the exponent positive Multiply both sides by r² Wr²=c Divide by W r²=C/W Then square root= R=sqrt(C/W) b.
