Answer:
Conservation of mechanical energy
Explanation:
Law of Conservation of Mechanical Energy: The total amount of mechanical energy, in a closed system in the absence of dissipative forces (e.g. friction, air resistance), remains constant.
In the absence of air resistance, the mechanical energy of an object moving through the air in the Earth's gravitational field, remains constant (is conserved) while the opposite is the case when there is air resistance involved.
Answer: C) show only those costs that a manager can control.
Explanation:
Responsibility report is the accounting document that is provided to the management stages in an organization. This report shows all the amount of all the expense of the service and product along with extra added product and performance reports that is supervised and controlled by manager.
Other options are incorrect because general accounting guidelines, variable amount and preparation at top most level of manger is not followed by responsibility report.Thus, the correct option is option(c).
Answer:
The correct answer is B. They are a collection of minerals or a body of glass.
Explanation:
The study of rocks needs the observation of their characteristics; its characteristics depend on the properties of the minerals that compose it, its relative amounts and the way in which these were joined to originate the rock. Texture is the external appearance of any rock. It depends on the shape, size and internal arrangement of mineral crystals. Each of these characteristics maintains its specific properties (chemical and physical) in the rock as a whole.
In a rock we can distinguish two types of minerals:
Essential minerals. They are the ones that constitute the nature of the rock and give it its characteristics and properties for being in greater proportion. The lack of one of them would result in the formation of a different rock with different properties.
Accessory minerals These are minerals that appear occasionally in very low proportions within the typical composition of a particular rock. Its presence does not alter the basic characteristics of the rock.
Most of the research on adolescents has
been carried out with white, middle class samples.
To add, research on
adolescence<span> uses both
quantitative and qualitative methodologies applied to their cognitive,
physical, emotional, and social development and behavior. A popular research that
tackles this can be found in the book, <span>Journal of Research on Adolescence.</span></span>
