Determine the ratio of the resistivity of pure water to silver?
kondor19780726 [428]

Answer:

3 \cdot 10^{11} : 1

Explanation:

Silver is a generally excellent conductor, this implies its resistivity is low (from table, we can check the exact worth i.e \rho_s = 1.6 \cdot 10^{-8} \Omega m)

Pure water, rather, is an extremely awful conductor, this implies its resistivity is exceptionally high, of order of k \Omega \cdot m (10^3 \Omega m )

Indeed, even without knowing the exact estimation of the pure water resistivity, we can appraise the proportion between the pure water resistivity and the silver resistivity by looking at the two orders of magnitude:

r= \frac{10^3 \Omega m}{10^{-8} \Omega m}  \sim 10^{11}

Therefore, we can say that the correct answer is

3 \cdot 10^{11} : 1

The field of physics which deals with the study of probability waves that describe the motion and dynamics of particles with mas
goldenfox [79]

Answer:

Option B. quantum mechanics

Explanation:

Quantum Mechanics, at atomic and sub-atomic levels deal with the study of how particles at this level behave and how the matter and energy interacts.

It also explains the properties of atoms, molecules and the particles constituting these.

The wave- particle duality of quantum mechanics that says that matter or every quantum of it exhibits wave as well as particle nature.

This theory was incorporated with its mathematical description given by Schrodinger was also incorporated in the theory for eave-particle duality and The probability for the existence of particle was determined.
