$a).$ (1) on the earth $b).$ $\approx$ 5.5 kg
a). The pound is defined as weight on earth of an object of mass 0.454 kg as we see in the packing. This sign is true on earth, because on other places the gravitational acceleration is different. b). $w=\frac{mg}{6}$ $m=\frac{6w}{g}=\frac{6\times 2\times 0.4536\times 9.8}{9.8}\approx5.5kg$
