a) According to the right-hand rule, the direction of the magnetic fields of the 3 wires are shown: We find the magnetic fields B1, B2 and B3: 퐵1=퐵2= 푢0 푖 = 푢0 푖 = 4∗3.14×10−7 ∗(3.65) =ퟒퟐ.ퟔퟔퟎ풖푻 2휋푟 2휋( 2푎) 2 ∗ 3.14 ∗( 2(0.0121)) 퐵3= 푢0 푖 = 푢0 푖 = 4∗3.14×10−7 ∗(3.65) =ퟐퟎ.ퟏퟏퟎ풖푻 2휋푟 2휋(3푎) 2 ∗ 3.14 ∗(3∗(0.0121)) The x components of the B1 and B2 cancel each other; therefore the net magnetic field will be downward and we have (the negative sign is because the direction is downward): 퐵=− 퐵1cos 45 +…

In the organic disordered materials, the charge transport is occurred by variable range hopping (VRH) of charge carriers between strongly localized states [22-25, 30, 58-61]. The VRH model proposed by Vissenberg and Matters model that considers the hopping percolation of thermally activated carriers between localized states is the most model used for describing charge transport in the disordered organic semiconductors and modeling the electrical characteristics OTFTs [27, 58]. Indeed, the…

where the proton of the beta- plus is found in the radionuclide. The nucleus then makes neutrons which then give out positrons which are beta- plus particles. When the neutron transforms into a proton, the proton stays back in the nucleus and the electron that is formed moves away with a lot energy. As the beta –plus particle emits the nucleus, it results in the nucleus changing and gaining one extra proton and losing one neutron. The atom that can be used in beta – plus is carbon 11. The other…

STEPS IN BALANCING REDOX EQUATIONS 1) Assign the Oxidation Numbers The Oxidation Number (ON) of an element is its charge. It is the number of electrons an element contains. This would be our basis on whether the element gained or lost electrons in chemical reactions. We can say that an element is in its Oxidation State when the element already has a specific ON. Unlike with our previous examples, not all equations would already reveal the ON of each element. In actuality, equations would…

Superfluid helium or He II is a macroscopic quantum fluid that exhibits extraordinary properties. %By applying the limit of low flow velocities, The behavior of the fluid can be understood using a Landau - Tisza model, where He II is considered to be a two-component fluid with independent velocity fields: the inviscid superfluid of density $\rho_s$, and the normal fluid of density $\rho_n$, where the total density $\rho$ = $\rho_s$ + $\rho_n$ \cite{Tisza,Landau}. The superfluid has neither…

Ionization is effected by a high energy beam of electrons (Reusch, 2013). When high energy electrons collides with a molecule, one of the molecular electrons will be knocked away, leaving behind a molecular cation (Anon., n.d.). Residual energy from the collision may cause the molecular cation to fragment into neutral pieces and smaller fragment cations…

5.1: Physical configuration and coordinate system The objective of the present chapter is to analyze the Soret and Dufour effects on unsteady MHD flow past an oscillating vertical plate by taking into account of viscous dissipation. MATHEMATICAL FORMULATION The plate is…

Ligands have one electron pair to donate to a metal atom and are called complex agents. • Metal atoms are Lewis acids because they can accept pairs of electrons from Lewis bases. • Within a ligand, the atom that is directly bonded to the metal atom/ion is called the donor atom. • A coordinate covalent bond is a covalent bond in which one atom (i.e., the donor atom) gives both electrons. This type of bonding is different from a normal covalent bond in which each atom supplies one electron. • If…

observation cannot be explained by using Hooge’s relationship. 1.2.2 The McWhorter Model According to this model, fluctuations in the surface density of electrons, which results into fluctuation in conductivity, arise from exchange of electrons between the surface layer and traps lying in the oxide layer covering the surface. The transfer of electrons took place via tunneling. Since the tunneling probability decreases exponentially with separation between surface and trap, so does the…

negative magnetic source was near it. From the classical physics of Newtonian physics, he figured that opposites attract and likes repel. Since the cathode rays followed the similar approach, hence they were determined to be negatively charged or electrons. Therefore, using previously held theories, further discoveries can be made and new theories can supersede…
