What is the zero error and the reading uncertainty for meter rule?
The zero error (if positive) is the distance from the edge of the ruler to the point where the actual measurements begin or (if negative) is the length that has been lost - through abrasion - before the point where the measurements should start. Many meter rules are marked in centimetres. The reading uncertainty for such rules is 0.5 cm (= 5 mm).
What is the accuracy of a meter rule?
0.5mm
What is the smallest reading on the meter rule?
0.5
What is the range a meter rule can go to?
Normally from 0 to 1 metre.
Which measures of an average classroom is closest to 1 meter?
A metre rule.
What is the zero error and the reading uncertainty (error) for a meter rule?
The zero error for a meter rule is when the ruler's zero marking is not aligned with the starting point of the measurement scale. The reading uncertainty for a meter rule can typically be within ±0.5 mm due to parallax errors or imperfections in the ruler.

What is the function of a meter rule?
Measurement of length.
When uncertainty in position of an electron is zero what will be uncertainty in momentum?
If the uncertainty in the position of an electron is zero (meaning it is known precisely), then according to the Heisenberg Uncertainty Principle, the uncertainty in its momentum would be infinite. This is because the product of the uncertainties in position and momentum must be greater than or equal to a certain constant value determined by Planck's constant.
What is the accuracy of a meter rule?
0.5mm
What is the difference between a meter rule and a meter ruler?
If the calibration starts from the edge of the stick then it is a meter rule Basically "0" starting from the edge And if it is a meter ruler ,there is like half inch of empty space before 0
What is the smallest reading on the meter rule?
0.5
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.
Why should meter rule be balanced on the wedge edgewise?
Balancing the meter rule on the wedge edge-wise ensures that the weight of the meter rule is evenly distributed on both sides, leading to a stable and accurate reading. Placing it edgewise helps minimize the effect of friction and other external forces that may affect the balance of the rule.
What meter rule used for?
Measuring anything up to a metre (meter in USA); drawing straight lines. Rule is the "proper" word for what most of us call a ruler.
What type of meter shows reading on a non-linear scale?
-- analog ohm-meter -- analog power meter -- analog audio level meter -- slide-rule multiplication/division scales -- slide-rule tangent/cotangent scales -- analog tuning dial on an AM radio
Which accounting rule requires that a degree of caution should be applied when preparing financial statements under conditions of uncertainty?
Reliability
