Answer :
Final answer:
The mass of an object is determined using a beam balance by placing the object on one side of the balance and adding known weights to the other side until equilibrium is reached. The total weight added to reach equilibrium equals the mass of the object.
Explanation:
The mass of an object can be determined using a beam balance through a process known as mechanical weighing. First, the object is placed on one side of the balance. After that, known masses are added to the other side until equilibrium is achieved (when the beam is level). The mass of the object is equal to the total mass added to the other side of the balance.
For instance, if you have an object on one side, and you've added weights of 20g, 50g, and 30g on the other side until equilibrium is reached, then the mass of the object is 100g (20g + 50g + 30g).
