# What is Polar Radius?

The Earth's Polar Radius is the distance from the center to its north or south pole.

Polar Radius of Earth equals to 6,356.7523 km.

### Give The formula for radius of curvature in polar form?

The radius of curvature is given by (1) where is the curvature. At a given point on a curve, is the radius of the osculating circle. The symbol is sometimes used instead of to denote the radius of curvature (e.g., Lawrence 1972, p. 4). Let and be given parametrically by (2) (3) then (4) where and . Similarly, if the curve is written in the form , then the radius of curvature is given by

### What is the radis of Jupiter?

Jupiter has about 11 times the diameter (or radius) of Earth. Wikipedia lists its radius as: Equatorial radius: 71,492 Â± 4 km Polar radius: 66,854 Â± 10 km Note that there is quite a big difference between the two; since Jupiter rotates quite fast, it is "stretched out" in the horizontal direction.

### How large is the moon?

The Size of the Moon is:- The average diameter is 3,475 kilometers (2,159.3 miles) The average radius is 1,737.10 km (1079.6 Miles) The equatorial radius is 1,738.14 km (1,080.03 miles) The polar radius is 1,735.97 km (1,078.68 miles) A little more than a quarter of that of the Earth. The polar diameter is 2157.36 miles The equatorial circumference of 6786.03 miles and angular diameter of 30 arc minutes 59.61 arc seconds.

### Does silicon dioxide have polar bonds?

Yes it does. The electronegativity difference between silicon and oxygen is significant enough to make the bond polar. However, silicon dioxide is technically a non-polar molecule, although it is not a likely compound due to silicon's larger atomic radius and its inability to easily form pi-bonds with oxygen.

### What is Equatorial Radius?

Half the distance in a straight line from one side of a planet to the other through the centre of the planet with the distance measured from the equaor on both sides. In other words, the radius of the sphere of the planet measured, not at the pole, but at the equator. It is important to distinguish between polar radius and equatorial radius because no planet is an exact sphere, but 'bulges out' at the…

### Is HI polar?

A molecule's polarity has two main contributing factors: symmetry and bond polarity. In order for a molcule to have poles, it must be asymmetrical and contain polar bonds. In the case of HI, the molecule is asymmetrical, however the difference in the electronegativities between hydrogen (with an electronegativity of 2.1) and iodine (with an electronegativity of 2.5) is technically too small for the H---I bond to be polar. However, there is a characteristic associated with…

### How much bigger is Jupiter than Saturn?

How much bigger Jupiter is than Saturn depends on what characteristic your are comparing (radius, mass, etc.) Jupiter has a mass 3.340 times that of Saturn Jupiter has a polar radius 1.230 time that of Saturn Jupiter has an equatorial radius 1.1862 time that of Saturn. Jupiter has an estimated surface area 1.456 times that of Saturn Jupirer has a volume 1.730 times that of Saturn.

### Are earth and the other planets perfectly round?

No, although the planets may seem spherical, they are actually flattened somewhat at the poles. The planetary spin on its axis pushes the equatorial part outward. Saturn, for example, has a radius of 54,300 km toward the poles but 60,200 km toward the equator. Earth is much closer to spherical with only a 22 km difference between the polar radius vs. the equatorial radius.

### What is the distance to the center of the earth?

The Earth is not a perfect sphere, instead it is an oblate ellipsoid (it bulges at the equator and is flattened at the poles). As such the distance to the centre of the Earth is larger at the equator than at the poles. The Earth's equatorial radius = 6,378 km (3,963 miles). The Earth's polar radius = 6,356 km (3,949 miles). Please see the related link.

### What measurement is earth's latitude and longitude system based of?

It's a system of 3-dimensional "Polar coordinates" (R, Θ, and Φ), with its origin at the center of the Earth, and every point of interest always at the same radius. ' R ' is the Earth's radius. ' Θ ' is the longitude of the point. ' Φ ' is the latitude of the point. Note that latitude and longitude are angles, not distances.

### What percentage of the Sun's radiated Energy does the Earth receive?

That can be calculated quite easily. Earth has a radius of 6367 km (I took the average of the "polar radius" and "equatorial radius" on Wikipedia; though it really doesn't matter much which one you take). That makes for a cross-sectional area of pi x radius squared = 12.74 million (square kilometers).A sphere, centered on the Sun, with a radius of 149.6 million kilometers (the mean distance from Earth to Sun) would be 4 x…

### What is the radius of earth?

Earth's Circumference at the Equator: 24,901.55 miles (40,075.16 km) Earth's Circumference Between the North and South Poles: 24,859.82 miles (40,008 km) Earth's Diameter at the Equator: 7,926.28 miles (12,756.1 km) Earth's Diameter at the Poles: 7,899.80 miles (12,713.5 km) Average Distance from the Earth to the Sun: 93,020,000 miles (149,669,180 km) Average Distance from the Earth to the Moon: 238,857 miles (384,403.1 km) Radius of Earth = 6 378.1 kilometers or about 3961.3 miles. Radius…

### How do you make a circle graph?

There are two common ways to graph circles: using a cartesian graph and using a polar graph. For a cartesian graph, there are two familiar axes x and y which are orthogonal to each other. The formula for a circle is "x^2 + y^2 = a constant". In a polar graph, there are no axes and all points are defined by their radius from the center point, and the angle of the direction the point…

### What is a polar equation?

If a point P is unrestricted, both r and theta can independently take any value. but if P is constrained to a particular path the values that r and or theta can take are limited. e,g. P LIES ON A CIRCLE WITH CENTRE O AND RADIUS A THEN FOR ALL POSSIBLE POSSITIONS PF p r=a thus r=a is the polar equation of the locus of P. If a point P is unrestricted, both r and…

### How large is the Earth?

The Earth has:- Polar Radius: 6,356.8 km (3,950 miles) Equatorial Radius: 6,378.1 km (3,963 miles) Mean Radius: 6,371 km (3,958.75 miles) Mean diameter: 12,742 km (7,917.5 miles) Equatorial circumference: 40,075.02 km (24,901.24 miles) Surface area: 510,072,000 km2 (196,939,900 miles) Volume: 1.0832073 × 1012 km3 Mass: 5.9736 × 1024 kg The diameter of the earth at the equator is 7,926.41 miles (12,756.32 kilometers).

### Is Jupiter round?

In general, planets are considered round, although they may not be perfectly round. Jupiter's equatorial radius is about 71,500 km, and its polar radius is about 66,800 km, indicating that it bulges at the equator; it is a little "stouter" than it is "tall". Earth has the same general characteristic. No object in the solar system has a geometrically perfect shape, and it is not likely that any objects in the universe do, either.
