Evaluate ( 152 mN ) 2 to three significant figures and express the answer in SI units.?

To evaluate ( (152 , \text{mN})^2 ), we first convert millinewtons to newtons: ( 152 , \text{mN} = 0.152 , \text{N} ). Squaring this gives ( (0.152 , \text{N})^2 = 0.023104 , \text{N}^2 ). Rounding to three significant figures, the result is ( 0.0231 , \text{N}^2 ).
