They were pretty bad at using a ruler. Also, no ruler can measure with an accuracy of 0.01 cm so clearly the students were picking some numbers at random.
Usually on one side they are centimetres (numbered) with millimeters (marked but not numbered). On the other side there are inches (numbered) with eighths or tenths or sixteenths or even thirty-secondths (marked but not numbered).
Finding the weight of a ruler using momentsApparatus:Metre ruler, knife edge, set of 100g masses [M20C]Diagram:Procedure:1. Place the metre ruler (without the weight shown in the above diagram) on the knife edge so that it is balanced.The knife edge should be roughly below the 50cm mark on the ruler. Note down the precise position of the knife edge below the ruler to the nearest mm. This is the position of the ruler's centre of gravity.2. Place a 100g mass, a weight of 1N, near the left-hand end of the ruler as shown in the diagram above.The ruler will tip down on this side.3. Move the knife edge towards the weight until the ruler again balances.Measure the distance p (in mm) between the centre of the weight and the new knife edge position and thedistance q (in mm) between the new knife edge position and the position of the centre of gravity of the ruler(see diagram above).4. Record your measurements in a table with the headings shown below.5. Repeat stages 2 to 4 for weights of 2N (using 200g of mass) to 9N (900g mass).Calculations:1. When the ruler is balanced the anticlockwise moment caused by the weight of the masses is equal to the clockwise moment caused by the weight of the ruler.Therefore:weight of mass, W (N) x distance p (mm) = ruler weight R (N) x distance q (mm)2. Calculate the value distance, q divided by weight of mass , W [q / W] for each of your results in the appropriate column in the table.Weight of mass Win newtonsDistance p(mm)Distance q(mm)q divided by W(mm/N)3. Draw a graph of distance p (mm) [Y-AXIS] against q / W (mm/N) [X-AXIS]4. Measure the gradient of this graph.The gradient is equal to the weight of the ruler in newtons.Write out clearly your answer.5. Explain why the gradient of your graph equals the weight of the ruler

If you look at the ruler you will see any tabs that have been manually set, as they will be on the ruler. Default tabs are shown below the ruler.If you look at the ruler you will see any tabs that have been manually set, as they will be on the ruler.

Usually, yes. They are shown as marks but not numbered. They appear on the metric scale, but it is centimetres (= 10 mm) that are numbered. Up to 30 on a 1 ft ruler, to 15 on a 6" ruler.

LINEAR!! I googled it for a project! Good luck!
The units of length on a ruler are typically in inches and centimeters. Each inch is divided into smaller units, such as eighths or sixteenths, while centimeters are divided into smaller units called millimeters.

You cannot see 9.44 inches on a ruler. The inches are often - though not always - marked in tenths. 9 inches will be shown on the ruler. From there move four small units towards the 10 inch mark. That is 9.4 inches away from the 0. Slightly less than half a mark further along is 9.44 inches.

Rubbing has transferred some charges from the comb to the ruler. In diagram b, rubbing with a cloth has transferred some charges from the balloon to the sweater.
she is the best ruler because she loves Canadian bacon.
No; he was the ruler.
