Interestingly, outer planets are known as Jovian planets because of their similarities with Jupiter. How are the outer planets different from each other?

The characteristics that the outer planets have in common include their large size and their large number of moons when compared with the inner, or terrestrial, planets. They also lack solid surfaces, and as far as astronomers know, none are capable of supporting life.

Like the Inner Planets, the Outer Planets share similarities but each also has its own unique characteristics. As well as all being huge and being made up mostly of gases, all four have rings spinning around them, with Saturn having the most famous rings. All four planets also have large numbers of moons orbiting them.

Answer: The answer is D. They are mostly made up of hydrogen and helium.

: of, relating to, or characteristic of the god or planet Jupiter.

A planet designated as Jovian is hence a gas giant, composed primarily of hydrogen and helium gas with varying degrees of heavier elements. In addition to having large systems of moons, these planets each have their own ring systems as well.

The coin would not float though, if you put it in vertically (as it would break the surface layer of water). The coin will sink in most situations though (if it is flat).

They sink because the objecct has more mass than water. So, that means that the water lets the object, like steel, sink.

A small, heavy object has higher density than a large light object. Lego bricks have many air bubbles trapped inside them. The density of the brick with all those bubbles is less than that of water – so the bricks float, no matter how many of them you stick together.

If an object is more dense than water it will sink when placed in water, and if it is less dense than water it will float. Density is a characteristic property of a substance and doesn’t depend on the amount of substance.

If an object floats in water, the weight of the water displaced is greater than the weight of the body immersed in water. Water is the only fluid that can provide buoyancy.

What’s so special about ice that causes it to float? Believe it or not, ice is actually about 9% less dense than water. Since the water is heavier, it displaces the lighter ice, causing the ice to float to the top.

This is because water is incompressible. Because the volume is the same at any depth, and the density of water is the same at any depth, the total mass of displaced water (mass = volume x density) is the same at any depth—making the buoyant force constant.

The deepest water is not a very large fraction of the way to the center of the Earth. People are full of air and other things that are less dense than water. This density shift makes them sink much faster.

Will a swimmer gain or lose buoyant force as she swims deeper in the water? Or will her buoyant force remain the same at greater depths? The swimmer will lose buoyant force because she displaces less water.

When objects sink, the volume of water they displace is greater than the volume of the object. The principle may seem relatively simple: Light objects float and heavy objects sink. However, you can make even heavy objects float by taking advantage of surface area and weight dispersal.
