WebDec 1, 2024 · Extreme high tides called spring tides, happen twice each month. 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. Web4. The K-Curve A numerical figure that considers the non-ideal condition of the atmosphere resulting to atmospheric refraction that causes the ray beam to be bent toward the earth or away from the earth. 5.

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 ... Webequatorial bulge. The excess of the earth's equatorial diameter over the polar diameter.

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. WebEarth Bulge When planning for paths longer than seven miles, the curvature of the earth might become a factor in path planning and require that the antenna be located higher off the ground. The additional antenna height needed can be calculated using the following formula: 8 D2 H = where H = Height of earth bulge (in feet)
Because of a planet's rotation around its own axis, the gravitational acceleration is less at the equator than at the poles. In the 17th century, following the invention of the pendulum clock, French scientists found that clocks sent to French Guiana, on the northern coast of South America, ran slower than their exact counterparts in Paris. Measurements of the acceleration due to gravity at the equator must also take into account the planet's rotation. Any object that is stationary with r…
