Consider the ising ferromagnet, given by the spin hamiltonian h--jσσσ; - η σσ,. (ij) i-1 where j> 0, ai= t1 , and the first sum is over nearest neighbors on a simple triangular lattice. use the real-space renormalization-group scheme of niemeyer and van leeuwen, up to first-order terms, as dis- cussed in the last section, to obtain the thermal and magnetic critical exponents. consider the ising ferromagnet, given by the hamiltonian n m= -jσσ.σ; -η σσ, i=1 (ij) where j> 0, oi = ±1, and the first sum is over nearest-neighbor sites on a square lattice. choose a unit cell consisting of five spins, as indicated in figure 14.9. use the real-space renormalization-group scheme of niemeyer and van leeuwen to write a set of recursion relations up to first-order terms in the interactions. obtain the values of the thermal and magnetic critical exponents.

Did the proton move into a region of higher potential or lower potential? did the proton move into a region of higher potential or lower potential? because the proton is a negative charge and it accelerates as it travels, it must be moving from a region of higher potential to a region of lower potential.because the proton is a negative charge and it accelerates as it travels, it must be moving from a region of lower potential to a region of higher potential.because the proton is a positive charge and it slows down as it travels, it must be moving from a region of higher potential to a region of lower potential.because the proton is a positive charge and it slows down as it travels, it must be moving from a region of lower potential to a region of higher potential.request answerpart bwhat was the potential difference that stopped the proton? express your answer with the appropriate units.î”v î” v = nothingnothingrequest answerpart cwhat was the initial kinetic energy of the proton, in electron volts? express your answer in electron volts.ki k i = nothing ev request answerprovide feedback

Anybody wanna ? (picture included? )
