Question

The metric unit of force is the Newton (N), which is kg∙m/s^2. Convert 10 mg∙cm/s^2 to Newtons. Be careful when working with units.

A. 1 x 10^-2 N

B. 1 x 10^-5 N

C. 1 x 10^-6 N

D. 1 x 10^-7 N

Answer 1

solution
10 mg∙cm/s^2 = 10Kg 10^-6 .10^-2 m /s^2 = 1 Kg 10^1-6-2m / s^2
10 mg∙cm/s^2 = Kg 10^-7 m / s^2
so D. 1 x 10^-7 N
