What is the object marked?

To find the density of an irregular object one has to find the [blank_start]mass[blank_end] and the [blank_start]volume[blank_end] of the irregular object. The mass of the object is found using [blank_start]an electronic balance[blank_end] while the volume of the irregular object is found using a [blank_start]measuring cylinder[blank_end]. To find the volume of the irregular solid, one has to first insert a [blank_start]known volume[blank_end] of water and gently inserting the irregular object without splashing. The new volume is recorded and this is the highest volume. The initial (smallest) volume is [blank_start]subtracted[blank_end] from the final (highest) volume. This will equal the volume of the irregular object alone. The equation [blank_start]density=mass/volume[blank_end] is then used to find the density of the object.

The ruler was clamped a small distance behind the spring, making sure that the ruler and spring hang off the desk properly. 3. The distance between the two pointers recorded. This showed the [blank_start]un-extended length[blank_end] of the starting position of the spring. 4. The [blank_start]masses[blank_end] were gradually added and the new readings recorded, the ending position was marked. 5. The [blank_start]extension[blank_end] was found by subtracting the starting position from the ending position. 6. The results were tabulated and the force calculated
