What are the measurements on a meter stick?

It shows 12 inches and 30 centimeters. A 12-inch ruler is equal to 1 foot. A yardstick is a measuring stick that is one yard long and shows 36 inches. A meter stick is a measuring stick that is 1 meter long and shows 100 centimeters.

What is the smallest division on the Metre rule?

Using the Metric Ruler Consider the following standard metric ruler. The ruler is incremented in units of centimeters (cm). The smallest scale division is a tenth of a centimeter or 1 mm. Therefore, the uncertainty Δx = smallest increment/2 = 1mm/2 = 0.5mm = 0.05cm.

What is a Metre rule?

A meter rule is a device or a type of a ruler that is used to measure the distance and length of different items. A meter rule, just like the name suggests, has a length of one meter, which is the same as one hundred centimeters.

What is the uncertainty of an angle?

The uncertainty of measurement of standard angular optics is: ±0.2%θ ±0.5 ±0.1M µrad. The uncertainty of measurement of calibrated angular optics is: ±0.02%θ ±0.5 ±0.1M µrad. Where: θ is the angle measured in µrad. M is the linear measurement distance between the angular interferometer and angular reflector in metres.

How do you find the uncertainty of an angle?

Note: Uncertainty in angles must be in radians. 1. Find Z = W – X – Y, where W = 0.00123 ± 0.00007, X = 0.0032 ± 0.0008, and Y = -0.0061 ± 0.0009. The principle, or measured part, of Z is Z = 0.00123 – 0.0032 – -0.0061 = 0.00413 .

Do angles have uncertainty?

One of the sources of uncertainty in an angular or distance measurement occurs when the target sign is not perfectly centered. Its contribution to the uncertainty of the horizontal angle is: D = Distance measured. ρ = Hundredths of seconds which have a radian: An approximation of this value is: 636619,772.

What is the uncertainty of theta?

Given an angle θ=a∘±b∘ θ = a ∘ ± b ∘ , where a∘ is the measured value and b∘ is the uncertainty, the percent uncertainty is (b/a)×100%.

What is sine error?

Abbe error, named after Ernst Abbe, also called sine error, describes the magnification of angular error over distance. Abbe error is the product of the abbe offset and the sine of angular error in the system. Abbe error can be detrimental to dead reckoning.
