Why do the planets in our solar system stay in a system of organized motion? A). inertia keeps moving objects in motion

B). the sun’s gravity attracts the planets so they don’t fly off

C). inertia keeps the planets in motion and gravity prevents the planets from flying off into space

D). the perfect circular orbital paths allow planets to stay in regular motion

the product of the pressure and volume is also constant

ca has a crystalline lattice with positive ions (since it is a metal, metals are positively charged) and electrons flow freely in its structure since the ca atoms have a large nuclear radius so the electrons are not tightly held, therefore the electrons can flow freely since they are not being highly attracted by the nucleus. moreover, one of the properties of metals are that they are conductors of electricity, thus proving ca is the element.
