Answer:
So we want to know how can an object have three different weights at different times. So weight is Fg=m*g, where m is the mass of the objecct and g is the gravitational acceleration. On Earth, g=9.81 m/s^2, in space g is much less and on the moon g=1.625 m/s^2 So we see that the object changes its weight by moving it to space and on the Moon.
Explanation:
A heterogeneous mixture composes of non- uniform components, so the concrete would be the answer, because you can tell the components from one another.
