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.

water molecules have a weak, partial negative charge at one region of the molecule (the oxygen atom in water) and a partial positive charge elsewhere (the </span>hydrogen<span> atoms in water).The force of attraction is called a </span>hydrogen bond<span>.</span>
Robert Hooke was the first scientist to discover cell. This discovery was made possible by the use of microscope which he invented. With this microscope, Robert examined a cork and noticed pores which filled the entire volume of the thin slices of cork; he called the pores cells. This discovery was made in January 1653.
Movements of tectonic plates create volcanoes along the plate boundaries, which erupt and form mountains. A volcanic arc system is a series of volcanoes that form near a subduction zone where the crust of a sinking oceanic plate melts.
