WebAnswer and Explanation: 1. Due to the centrifugal force, which is acting on Earth at the equator but not at the poles. With increasing latitude, the radius r r of the circle on which a point on this latitude rotates becomes smaller. The angular velocity ω ω is constant, and the centrifugal force is proportional to the product of squared ... WebThe size of an equatorial bulge depends on the inverse of a planet’s density, and the square of its rotation speed. The average density of the earth is 4.15 times as great as that of Jupiter. Also Jupiter rotates once in 9.9 hours. (24/9.9) ² = 5.87, multiply that by 4.15 = 24.4.

Earth bulge In telecommunications , Earth bulge refers to the effect of earth's curvature on radio propagation. It is a consequence of a circular segment of earth profile that blocks off long-distance communications. See more Line-of-sight propagation is a characteristic of electromagnetic radiation or acoustic wave propagation which means waves travel in a direct path from the source to the receiver. Electromagnetic transmission includes … See more Low-powered microwave transmitters can be foiled by tree branches, or even heavy rain or snow.

A spring tide occurs when the Earth, Sun, and Moon are lined up. This happens twice each lunar month, during a new and full moon. The Sun and the Moon's gravity force pulls on the tidal bulges on the Earth's surface, resulting in an extremely high tide, a spring tide.
