It is a bubble
The liquid inside a density ball is usually a mixture of different liquids with varying densities, such as water, glycerin, or colored oils. The different densities of these liquids allow the ball to float at different levels when placed in a liquid.
No, a ball is not considered a shell structure. A shell structure is typically defined as a thin, curved material that provides strength and stability while enclosing a space, like a dome or a shell of an egg. A ball, on the other hand, is a solid object with a uniform shape and does not have the thin, hollow characteristics of a shell structure.
the shell
A solid metal ball would sink into the very viscous liquid, a hollow metal ball would float. The speed of descent is dependent on the density of the liquid.
Yes just subtract the volume of the ball from the volume you measure of the liquid.
It floats.
A solid.
no
The liquid is a solution of salt water and corn syrup
a yoga ball is a solid... yeah.
Rolling into a ball EDIT: It has a protective "shell" and most can curl into a ball.
one solid is a ball and another is a ice and a liquid is water or juice.
