A tennis ball consists of a pressurized rubber core covered with high-quality cloth, usually wool mixed with up to 35 percent nylon.
It is interesting to consider a closed ball where and Such a ball consists of two disjoint closed sets (a square and a segment) which, in particular, means that it is not connected.
The array can accommodate a maximum of 30 Compton suppressed Ge detectors coupled to various ancillary devices, such as a 4π inner ball consisting of 60 BaF2 crystals, 30 element 4π silicon detector array, compact scattering chamber equipped with 110 PIN diodes placed at backward angles and a conversion-electron spectrometer.
You will not go far without discovering the Mozartkugel (literally, "Mozart ball"), consisting of a core of marzipan and layers of nougat, the whole enrobed in dark chocolate and wrapped in foil bearing the likeness of the composer in a powdered wig.
Each brood ball consists of a chamber containing a single egg surrounded by packed dung that provides the resources for offspring development from hatching to adult emergence.
Using a hierarchical template synthesis scheme, we have synthesized a nanocarrier mimicking a golf ball, consisting of (i) solid silica core with a pitted gold surface and (ii) a hollow/porous gold shell without silica.
Most golf balls consist of a hard-rubber sac containing a liquid, a hundred feet or so of rubber thread wound at a fairly high tension, and a covering of balata.
Traditional three-piece balata-covered balls were still popular, but golfers could also choose from two-piece balls (with a solid core and a hard Surlyn cover), two-piece "performance" balls (with thicker cores and thinner covers, allowing for the feel and control of a three-piece ball), and three-piece double-cover balls (consisting of an inner core covered by two layers of varying hardness).
The Grip-ball consists of an airtight ball that contains a pressure sensor and Bluetooth communication system.
The Grip-ball consists of pressure and temperature sensors and an electronic wireless communication system contained in an airtight ball.
