In geometry, a parabola is a two-dimensional, mirror-symmetrical curve, which is modeled by a quadratic equation. Any point, line or object reflecting upon itself in a parabolic fashion is said to be its axis of symmetry. The latus rectum of a parabola is the chord of the parabola that ...
If the volume of a solid block is 300 cm^3, find the mass of water displaced when it is immersed in water. One of the sides of a parallelogram is 4.2 cm and the altitude to that side is 3.6 cm. Find the perimeter of the parallelogram...
Altitude of a triangle is basically the perpendicular line segment drawn from the vertex to the opposite side of the triangle. The altitude or height of a triangle may lie inside or outside the triangle. Learn with examples at BYJU’S.
In close-range photogrammetry the sensor is often close to the object of interest and is typically not nadir viewing, but rather looking horizontally, obliquely, or even upward in the case of mapping bridge engineering structure. This imagery is modeled mathematically in slightly different ways, hen...
What is the altitude of the orbit (called a "synchronous orbit")? What linear speed must an Earth satellite have to be in a circular orbit at an altitude of 185 kilometers ? What is the period of revolution? In the Greek geocentric model, the retrograde motion of a planet occurs when ...
A physical pixel on the focal plane of a sensor absorbs photons that become an electrical charge. That charge is converted to a number and placed into an array, or raster format. Because the position and altitude of the sensor at the exact moment of exposure is precisely known, the pixel'...
The early evolution of an F region structure that is initially confined in altitude is dominated by parallel diffusion. Low-altitude image structure growth ... RA Heelis,JF Vickrey - 《Journal of Geophysical Research Space Physics》 被引量: 36发表: 1990年 ...
In a regular oblique pyramid can some faces be congruent? What is fixed perimeter? Explain with an example. What Is perimeter? One of the sides of a parallelogram is 4.2 cm and the altitude to that side is 3.6 cm. Find the perimeter of the parallelogram if the altitude to the other sid...
To draw a circumcircle in geometry, you must first draw an altitude from each vertex of your triangle to the opposite side. This will create three smaller triangles within your original triangle. Using Pythagoras' theorem, you can then calculate the length of each altitude and use this ...
