11. The "'49th parallel north "'is a circle of latitude that is 49 equatorial plane . 12. Its center of gravity lies in the equatorial plane . 13. Four or more ligands may be bound to the uranyl ion in an equatorial plane . 14. The centrifugal force of the more rapidly spinning star slings out material in the equatorial plane . 15. Between 4 and 6 ligands can be accommodated in an equatorial plane perpendicular to the uranyl group. 16. Voyagers 1 and 2 arrived to Jupiter in 1979 1980 and traveled almost in its equatorial plane . 17. One of the things planetary scientists are investigating with Saturn is this tendency to move toward an equatorial plane . 18. "Voyager 2 " discovered six new small moons orbiting Neptune's equatorial plane , and they were named nitrogen ice particles. 19. The " force " is caused by the Earth's rotation and therefore is always parallel to the Earth's equatorial plane . 20. Hence, the angle between " n "-vector and the equatorial plane corresponds to geodetic latitude, as shown in the figure.
