What is the perimeter or circumference of an oval or ellipse?
It isn't possible to give a generalised formula for the circumference of an ellipse in terms of elementary functions. The circumference (or perimeter) of an oval is represented by an infinite series based on multiple aspects of the oval including: * Eccentricity * Implied length ("major radius") * Implied width ("minor radius")
What is Law of the sine?
The law of sines is a statement about arbitrary triangles in the plane.The law of sines states that in any right triangle, the ratio of the opposite side length to the length of the hypotenuse (relative to an acute angle) is always relative to the size of the angle. Put more simply, it means that if you take the sine of an angle, the value will be equal to the length of the opposite side divided by the length of the hypotenuse. The practical application of this is when you know the length of only one side and the measure of one angle (other than the right angle) you can determine the other sides and the remaining angle.The law of sines states that in any right triangle, the ratio of the opposite side length to the length of the hypotenuse (relative to an acute angle) is always relative to the size of the angle.

How do you change centimeters to percentages?
You cannot change centimeters to percentages. Centimetres are a measure of length while a percentage is a ration, a dimensionless number. Conversion from one to the other is not valid.
The length of a radius is the length of a diameter?
The length of a radius is not the length of a diameter. The diameter is two times the length of the radius.
What is the formula for finding the area and perimeter of a square?
The area of a square is: A = Width × Height or A = Length * Length = Length^2 The Perimeter of a square is: P = Length + Length + Length + Length = 4 * Length
What is the uncertainty of 1.93cm?
That is a statement of a fixed length. There is no uncertainty about that.
How do you calculate percentage uncertainty?
If the uncertainty is not written on the measuring instrument then you must estimate it yourself. Take half of the final certainty to which you can read the instrument. If you can read the instrument to 12.5 mm then the uncertainty is 0.25 mm. However, it makes no sense to have 0.25 as a two decimal point uncertainty, so in this case the uncertainty would be taken as 0.3 mm. Length = 12.5 ± 0.3 mm
How do you calculate elongation in post tensioning?
Elongation is the percentage of the final dimension relative to the initial dimension. For instance; A 1m length of metal is put under a load and is stretched to a final length of 1.5m The elongation of this is 150% because the final length is 150% of the initial length.
What is mercury's relative length of year?
5 days
What is the uncertainty in the measurement for the speed of light?
The uncertainty in the measurement of the speed of light is typically around ±0.3 meters per second. This uncertainty arises from various factors such as experimental errors, instrumental limitations, and environmental conditions. Multiple measurements and techniques are used to reduce this uncertainty and obtain a more accurate value for the speed of light.
What is the uncertainty associated with measuring length using a meter stick?
The uncertainty associated with measuring length using a meter stick is typically around 0.5 millimeters. This means that the measurement could be off by up to half a millimeter due to factors like human error or the precision of the instrument.
When an error of 1 percent is made in the length of a square the percentage error in the area of square will be?
The percentage error in the area of the square will be twice the percentage error in the length of the square. This is because the error in the length affects both the length and width of the square, resulting in a compounded effect on the area. Therefore, if there is a 1 percent error in the length, the percentage error in the area would be 2 percent.
Is length a constant?
No, length is a relative measure. If an object is travelling close to the speed of light it undergoes Lorenz contraction.
How do you convert one inch in to percentage?
You cannot. You may convert one inch as a proportion of another length as a percentage but no other length is given.
Is oxygen percentage affected by length of tubing?
NO
What is a doubt or uncertainty in measurement?
Basically your uncertainty is the innaccuracy or your measurement. For instance if you had a yard ruler that was marked only in inches and the length of the object you were measuring lied somewhere between 12 and 13 inches; you could state that the objects length is 12 1/2 inches ± 1/2 inch. The ± 1/2 part is your uncertainty, it means the measurement could be either 1/2 inch longer or shorter than your stated measurement.
What Length of a force arrow?
The length of a force arrow in a force diagram does not have a direct correlation to the magnitude of the force. The direction of the arrow indicates the direction of the force, while the relative length compared to other force arrows in the diagram shows the relative strength or magnitude of the forces.
