Your finger makes a bump when you rule a line
first line it up
by using a ruler
the answer is unknown error
Percent error is typically used to describe the difference between an expected value and an observed value (measured in an experiment). To calculate percent error, you must know the expected (or theoretical) value, determined from reference manuals and formulas. Percent error = [(actual measured value)/(expected value) - 1] x 100% Let's say that you do a chemistry experiment, where you expect to use 30 mL of a hydrochloric acid solution to neutralize a prepared solution of sodium hydroxide. When you perform the experiment, you actually use 30.2 mL of hydrochloric acid solution. Percent error = [(30.2 mL) / (30 mL) - 1] x 100% = 0.667 % error
Measure the depth using a metric ruler!
The experimental error when using a ruler can arise from several factors, including parallax error (misreading the measurement due to viewing angle), the precision of the ruler's markings, and human error in aligning the object with the measurement scale. Additionally, environmental factors such as temperature can cause expansion or contraction of the ruler material, affecting accuracy. Generally, the smallest division on the ruler indicates its precision, and the overall error can be estimated as half of this smallest division.
The uncertainty of a ruler refers to the smallest measurement that can be reliably determined using that ruler. It represents the margin of error in measurements taken with the ruler.
the spindle must be tighten to avoid slightly changes on the reading
The uncertainty of a ruler in centimeters refers to the smallest measurement that can be reliably determined using the ruler. This uncertainty is typically around 0.1 centimeters, meaning that measurements taken with the ruler may have a margin of error of up to 0.1 centimeters.

The common error message that occurs when using the lambda function in Python and providing more arguments than expected is "TypeError: lambda() takes X positional arguments but Y were given."
The metals molecules expand in the heat and is more easier to bend out of shape and warps, so it won't rule a straight line.
Depending on whether you subtract actual value from expected value or other way around, a positive or negative percent error, will tell you on which side of the expected value that your actual value is. For example, suppose your expected value is 24, and your actual value is 24.3 then if you do the following calculation to figure percent error:[percent error] = (actual value - expected value)/(actual value) - 1 --> then convert to percent.So you have (24.3 - 24)/24 -1 = .0125 --> 1.25%, which tells me the actual is higher than the expected. If instead, you subtracted the actual from the expected, then you would get a negative 1.25%, but your actual is still greater than the expected. My preference is to subtract the expected from the actual. That way a positive error tells you the actual is greater than expected, and a negative percent error tells you that the actual is less than the expected.
The greatest possible error in Bruce's measurement of the buckle as 3.2 cm depends on the precision of the ruler used. If the ruler has increments of 0.1 cm, the greatest possible error would typically be ±0.05 cm, meaning the actual length of the buckle could be anywhere between 3.15 cm and 3.25 cm. This range accounts for the smallest unit of measurement and ensures that the measurement is as accurate as possible.
To minimize errors when using a ruler, ensure that the ruler is positioned correctly and securely against the object being measured, avoiding any parallax error by viewing the measurement straight on. Use the appropriate side of the ruler for the scale needed, and ensure that the starting point (zero mark) is aligned with the edge of the object. Additionally, take multiple measurements and average them to account for any inconsistencies.
It depends on the type of ruler you are using. Depends if you are using a just metric unit ruler or if you are using a yard/meter stick. The measurements should be written along the edge of the ruler.
Make sure you are using the correct SI unit on the ruler.
