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

"hydrogen bonding is the attraction of h atoms in the water molecule (slight + charge) to o atoms in a neighboring water molecule (slight - charge); it is a weak interatomic force. but it is still strong enough to the water molecules "stick" together."

the density of gold = 19.3 g/cm3

the relation between density and mass and volume is

density = mass / volume

given :

mass of gold = 13 g

density = 13g / volume = 19.3

volume = 13 /19.3 = 0.67 cm^3

thus volume of gold nugget = 0.67 cm^3
