• A. decreasing order
• B. increasing order
• C. either increasing or decreasing order
• D. at random

Answer 1

Answer: (A)

decreasing order

When we are near to getting the actual weight in a beam balance, standard weights should be tried in decreasing order.

Meanwhile, let us look at the precautions in using a beam balance:
1. The weight should be replaced into the weight box after weighing.
2. Wet and hot objects should not be kept on the plan.
3. When near the actual weight ,weights should be tried in decreasing order.
4. The beam should be lowered before adding or removing weights from the pan.
5. The lever should be turned gently ,in order to prevent the knife edges from chipping.
