Explanation:
Plant drought tolerant species with low water needs. Plant trees in your yard, and retain trees on slopes and near waterways to contribute to improved water quality. Apply a 3-4” layer of mulch under the drip line of trees and throughout landscape beds to retain soil moisture and reduce watering needs.
Answer:
Beam balance is an apparatus used to measure mass of different objects by comparing it with a known mass. It consists of a horizontal beam with a support at its centre and depends on the gravitational pull on it.
Beam balance
The beam balance is used for calibrating masses in the range between 10 mg and 1 Kg. The measurement resolution and accuracy achieved depends on the quality and sharpness of the knife edge that the pivot is formed from. For high measurement resolution, friction at the pivot must be as close to zero as possible, and hence a very sharp and clean knife-edge pivot is demanded. The two halves of the beam on either side of the pivot are normally of equal length and are measured from the knife edge. Any bluntness, dirt, or corrosion in the pivot can cause these two lengths to become unequal, causing consequent measurement errors. Similar comments apply about the knife edges on the beam that the two pans are hung from. It is also important that all knife edges are parallel, otherwise displacement of the point of application of the force over the line of the knife edge can cause further measurement errors. This last form of error also occurs if the mass is not placed centrally on the pan.
