Why doesnt the meter stick hang straight when it has its pivot point at the 50 cm mark?
The 50cm mark isn't necessarily the ruler's centre of mass where it will balance. If the ruler is not uniform (i.e. it has a hole in it) its centre of mass will not be exactly in the middle.

How to find weight of a meter rule using a fulcrum and a 100g mass?
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
What tool can you use to find the mass of a computer disk should it be a ruler liter container or simple balance?
A balance will give you it's mass.

How do you find the density of a rectangular solid if the only instrument you have with you is a ruler?
To find the density of a rectangular solid with just a ruler, you would need to measure the length, width, and height with the ruler. Then, calculate the volume by multiplying the three measurements together. Finally, divide the mass of the rectangular solid by the volume to find the density.

How do you find the density of a perfect cube with a balance and a ruler?
To find the density you need the mass and volume and then, density = mass/volume. Given a ruler, you can easily measure an edge of the cube. If that is x units, then the volume is x3 cubic units. However, it is not clear how you find a mass with just a balance. You need some standard weights, but these do not appear to be provided. You are stuck and cannot answer the question.
How can you find center of mass of solid hemisphere?
To find the center of mass of a solid hemisphere, you can divide it into elementary components, such as disks or cylindrical shells, and integrate their individual masses over the hemisphere's volume. By dividing the mass-weighted points by the total mass, you can determine the coordinates of the center of mass in three dimensions.
Is a meter used to measure the mass of a bicycle?
No, a meter is not used to measure the mass of a bicycle. Mass is typically measured in units such as kilograms or pounds using a scale or balance. A meter is a unit of length, not mass.
