How do you calculate curves?

A simple method for curving grades is to add the same amount of points to each student’s score. A common method: Find the difference between the highest grade in the class and the highest possible score and add that many points. If the highest percentage grade in the class was 88\%, the difference is 12\%.

How far can you see from a certain height?

The formula for determining how many miles an individual can see at higher levels is the square root of his altitude times 1.225. Thus on a clear day at 1,000 feet a person with normal vision can see 39 miles; at 10,000 feet, 123 miles; at 25,000 feet, 194 miles.

How do you find a curved area?

Multiply the radius by the height. For example, a radius of 2 inches and a height of 10 inches would give you: 2 inches * 10 inches = 20 inches squared. Multiply Step 3 by 6.28: 20 inches squared * 6.28 = 125.6 inches squared.

How do you find a curved object?

The Chord is the distance straight across the curve, measuring straight across from point to point. This measurement should be made with a flat ruler. To measure the depth of the curve, take one half of the chord measurement and at that point measure to the top of the curve.

How do you calculate the area of curvature?

Multiply the radius by the height. For example, a radius of 2 inches and a height of 10 inches would give you: 2 inches * 10 inches = 20 inches squared.

How do you calculate how far you can see?

√2Rh = √41807040h = √41807040 5280 √h miles ≈ 1.22459 √h miles . For example, if our eye is 5 feet about sea level, then the horizon distance is about 1.22459√5=2.738 miles away.

How far can you see from 35000 feet?

The distance here is 170 miles.

How do you calculate curvature of the Earth?

The Earth has a radius of approximately 3965 miles. Using the Pythagorean theorem , that calculates to an average curvature of 7.98 inches per mile or approximately 8 inches per mile (squared).

What is the formula for curvature of the Earth?

CALCULATION OF EARTH, SHEAR AND CURVATURE VORTICITY . The first term is earth vorticity. All that is needed is the earth’s latitude to get this value. The formula for earth vorticity is: f =2* (omega)*SIN (THETA); where omega is the earth’s angular momentum and THETA is the latitude. The value of omega for the earth is 7.292*10^-5 rad/s.

How high do you have to be to see the curvature of the Earth?

To claim you can see “the curvature of the earth” from low altitude, like a hundred thousand feet or so, is like putting your eye a couple of thousandths of an inch from a large beachball and believing that you can see its curvature. The math is about the same.

How much does the Earth curve?

The Earth curves at approximately 8 inches per mile squared. However, Hidden by the curvature of the Earth. So if your line of sight is 6ft from the ground or sea, and you’re looking across calm sea, your horizon will be 3 miles away.
