Answer:
Mohs hardness, rough measure of the resistance of a smooth surface to scratching or abrasion, expressed in terms of a scale devised (1812) by the German mineralogist Friedrich Mohs. The Mohs hardness of a mineral is determined by observing whether its surface is scratched by a substance of known or defined hardness.

To give numerical values to this physical property, minerals are ranked along the Mohs scale, which is composed of 10 minerals that have been given arbitrary hardness values. The minerals contained in the scale are shown in the Table; also shown are other materials that approximate the hardness of some of the minerals. As is indicated by the ranking in the scale, if a mineral is scratched by orthoclase but not by apatite, its Mohs hardness is between 5 and 6. In the determination procedure it is necessary to be certain that a scratch is actually made and not just a “chalk” mark that will rub off. If the species being tested is fine-grained, friable, or pulverulent, the test may only loosen grains without testing individual mineral surfaces; thus, certain textures or aggregate forms may hinder or prevent a true hardness determination. For this reason the Mohs test, while greatly facilitating the identification of minerals in the field, is not suitable for accurately gauging the hardness of industrial materials such as steel or ceramics. (For these materials a more precise measure is to be found in the Vickers hardness or Knoop hardness) Another disadvantage of the Mohs scale is that it is not linear; that is, each increment of one in the scale does not indicate a proportional increase in hardness. For instance, the progression from calcite to fluorite (from 3 to 4 on the Mohs scale) reflects an increase in hardness of approximately 25 percent; the progression from corundum to diamond, on the other hand (9 to 10 on the Mohs scale), reflects a hardness increase of more than 300 percent.
Answer:
(She yells out again) And I don’t want any back talk, you hear?
Explanation:
Kate's viewpoint that helps the audience understand that Eugene is disrespectful to her is seen in the above line:<em> (She yells out again) And I don’t want any back talk, you hear?</em>
From the interaction/dialogue between Kate, Blanche and Eugene, we discover that Eugene wasn't happy when he was told to put out the water glasses.
Blanche preferred to do it herself but Kate replied, <em>"Why? Is his arm broken? (She yells out again) And I don't want any back talk, you hear?"</em>
Then Eugene, <em>(Slams the ball into his glove angrily. Then he cups his hands, making a megaphone out of it and announces to the grandstands)</em>
Kate's statement that she doesn't want back talk actually reveal that Eugene is disrespectful; also, Eugene's angry disposition reveals that too.
