A. 1/2 times B. 1/3 times C. 1/78 times D. 1/58 times The Coulomb force between two charges in a medium is given by Coulomb’s law, which states that the force is inversely proportional to the dielectric constant (relative permittivity) of the medium. Water has a high dielectric constant, which significantly reduces the Coulomb force … Read more
A. The speed of sound B. The speed of other object C. The speed of light D. The speed of air resistance The correct answer to the question: “Mach is the unit of measurement in stating the speed of a moving object in relation to__________?” is “The speed of sound”.
A. Isochoric B. Isobaric C. adiabatic D. Isothermal The term “adiabatic” refers to a process in which no heat is transferred into or out of the system. This means that the system is thermally isolated from its surroundings, resulting in no heat exchange. A. Isochoric: An isochoric process is a thermodynamic process in which volume … Read more
