Answer :
Final answer:
The weight of the object being measured using the triple beam balance is determined by adding up the weights indicated on each beam. In this case, the object has a weight of 121 grams.
Explanation:
In the scenario mentioned, the student is using a triple beam balance which is a type of mechanical balance used for measuring masses. Each beam on the balance represents a different measure of mass. In this case, the masses shown on each beam are 100g, 20g, and 1g. To find the total weight of the object being measured, simply sum up the weights indicated on each beam.
So, the weight of the object will be 100g + 20g + 1g = 121g. Therefore, the object the student is weighing has a mass of 121 grams.
