Answer :
Final answer:
The total mass of the object being measured in a triple beam balance, as per the weights given, is 25.5 grams.
Explanation:
The mass of the object being measured in the triple beam balance is calculated by summing up the readings on the three beams. On a triple beam balance, the mass is determined by moving three different sliding weights. As per your description, the large slider is at 0 g, the medium slider is at 20 g, and the small slider is at 5.5 g. Therefore, add these weights together to find the mass.
So, 0 g (from the large slider) + 20 g (from the medium slider) + 5.5 g (from the small slider) = 25.5 g.
Therefore, the mass of the object as measured by the triple beam balance is 25.5 grams.
