1. Rugby union uses an oval ball ( a prolate spheroid ). 2. He'd tell you it's more like a fully inflated prolate spheroid. 3. In three dimensions, the nebula is thought to be shaped like a prolate spheroid. 4. This theory gives the solutions to the Maxwell equations for prolate and oblate spheroidal particles. 5. Under these conditions, the droplet will periodically deform between prolate and oblate ellipsoidal shapes. 6. The berry in the shape of a prolate spheroid, like that of a rugby ball. 7. The intrinsic viscosity is very sensitive to the axial ratio of spheroids, especially of prolate spheroids. 8. Australian rules uses an oval ball ( a prolate spheroid ), similar to a rugby ball. 9. The ratio of axes of Cordelia's prolate spheroid is 0.7 ?0.2. 10. The ratio of axes of Cressida's prolate spheroid is 0.8 ?0.3.
