Answer :
Final answer:
A triple beam balance and an electronic balance are both used to measure the mass of an object, but they differ in how they do it. A triple beam balance is a mechanical balance that works by comparing the unknown mass to a set of known masses on three beams. On the other hand, an electronic balance measures mass using a load cell and a digital display.
Explanation:
A triple beam balance and an electronic balance are both used to measure the mass of an object, but they differ in how they do it.
A triple beam balance is a mechanical balance that works by comparing the unknown mass to a set of known masses on three beams. The user adjusts the position of the weights on each beam until the pointer is centered, indicating that the masses are equal. The mass of the unknown object is then read from the position of the weights. In contrast, an electronic balance measures mass using a load cell and a digital display. It uses a strain gauge to convert the force exerted by the object into an electrical signal, which is then displayed as the mass.
