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:
Hardness is the answer I believe
a process by which molecules of a solvent tend to pass through a semipermeable membrane from a less concentrated solution into a more concentrated one, thus equalizing the concentrations on each side of the membran.
Answer:
It depends entirely on an equation, certain equations are meant to confuse you with numerous answers so taht you have to narrow it down, some only have one or a few. It really depends on the type of problem
