The length of a copper wire is 1.6 centimeters (cm). what is the length of this wire in meters (m)?

We are being asked here to convert the length of a copper wire in the units of centimeters to the units of meters. We need a conversion factor to multiply to the value in order to obtain it's equivalent in meters. From the SI unit system, we know that in 1 meter there are 100 centimeters. Therefore,

1.6 cm ( 1 m / 100 cm ) = 0.016 m

Due to gravitational force

We know that,

            weight (W) =  m. g  Newtons

            Where m = mass , in Kg

                        g = gravitational force (m/s²)

                           = 9.8 m/s (it is constant on earth)

         So, from equation we knew that Weight is proportional to the gravitational force assuming fixed mass.

      On the moon the gravitational force (g) is very less compared to the earth gravitational force, i.e., 1.62 m/s²

       Therefore from equation of weight W = m. g is very less by considering the gravitational force on moon.

So, obviously weight changes on moon due to gravitational pull
