Final answer:
The mass of the object being measured on the triple beam balance, as determined by summing the positions of all sliders, is 25.5 grams.
Explanation:
A triple beam balance is a tool used to measure the mass of objects precisely. It has three sliding weights (also known as riders or beams) that you adjust until the bar balances. Each beam contributes to the total mass measured.
In your triple beam balance, the large slider is at 0g, the medium slider is at 20g, and the small slider is at 5.5g. To find the total mass of the object, you simply combine the mass from each beam. That is, 0g (from the large slider) + 20g (from the medium slider) + 5.5g (from the small slider).
So, the object being measured on the triple beam balance has a total mass of 25.5g.
