Answer:
plz mark as brainliest
Explanation:
This must be set to read 0.00 g. The triple beam balance has a little knob under the pan which you screw in or out to set the empty balance to read exactly 0.00 g. So, in weighing an object directly on the pan, you must first Zero the balance. Only if the balance is properly zeroed, will it weigh the object correctly
It has a beam which is supported by a fulcrum. On one side is a pan on which the object is placed. On the other side, the beam is split into three parallel beams , each supporting one weight. In measuring the weight of an object, rather than adding additional weights, each of the three weights can be slid along the beam to increase their lever arm.
It works just like a tetter-totter. If you have two people of unequal weight, the heavier person sits closer to the fulcrum to decrease their lever arm.
here is your answer
Answer:
To prove that a Beam Balance is a perfect balance:
1. The beam of the beam balance must be in horizontal position.
2. The needle near the fulcrum must be pointing to the balance sign.
3. The pans of the beam balance must be at equal height from ground.
Explanation:
If all conditions are fulfiled, the beam balance is perfectly balanced.
