Does higher frequency mean better sound? The answer to this question is clearly no. You might suspect, that the higher the frequency, the louder we perceive a noise, but frequency does not tell us how loud a sound is. Intensity or loudness is the amount of energy of a vibration and is measured in decibels […]
Does viscosity depend on nature of liquid?
Does viscosity depend on nature of liquid? The viscosity is calculated in terms of the coefficient of viscosity. The value of this coefficient constant for a liquid depends on its liquid’s nature. What is the viscosity coefficient of liquid? Enter your search terms: The ratio of the shearing stress to the velocity gradient is a […]
How hard is 30 HRC?
Does a chemical reaction occur when boiling water?
Does a chemical reaction occur when boiling water? Answer and Explanation: No, boiling water is NOT a chemical reaction, but it is a physical change. When water, H2 O, is in liquid form, it can be heated to a boil. Is Steam a chemical reaction? A physical reaction causes the matter to shift shape or […]
What color dissipates heat the fastest?
What color dissipates heat the fastest? black What material stays cool in the heat? Since then, they and other researchers have made a host of materials, including films, spray paints and treated wood, that stay cool in the heat. These materials all rely on enhancing a natural heat-shedding effect known as passive radiative cooling. What […]
Is monoculture good or bad?
Is monoculture good or bad? Higher Revenues. By growing monoculture plants, farmers usually benefit from higher profits. For example, cultivating a single kind of crop that is best suited to development in specific climate conditions, allows the farmer to get better yields and, therefore, get higher income. Is monoculture farming sustainable? And the approach to […]
How is flux calculated?
How is flux calculated? The total of the electric flux out of a closed surface is equal to the charge enclosed divided by the permittivity. The electric flux through an area is defined as the electric field multiplied by the area of the surface projected in a plane perpendicular to the field. How does the […]
Which best describes the type of bond shown?
Which best describes the type of bond shown? Answer : The correct option is, (D) an covalent bond between the atoms. What produces an ionic bond? Ionic bond, also called electrovalent bond, type of linkage formed from the electrostatic attraction between oppositely charged ions in a chemical compound. Such a bond forms when the valence […]
Which soil is known as black soil?
Which soil is known as black soil? black soils known locally as regur. After those the alluvial soil is the third most-common type. Also significant are the desert soils of Rajasthan, the saline soils in Gujarat, southern Rajasthan, and some coastal areas, and the mountain soils of the Himalayas. The type of soil is determined […]
What happens to capacitance if distance is increased?
What happens to capacitance if distance is increased? Capacitance is directly proportional to the electrostatic force field between the plates. This field is stronger when the plates are closer together. Therefore, as the distance between the plates decreases, capacitance increases. Therefore, as the dielectric constant increases, capacitance increases. Is capacitance proportional to distance? Capacitance (C) […]
