2) If an object weighs 2500 N on earth, what is the weight of the object on a planet - the mass of the earth and 6 times the radius?

How do I solve for Problem 12.1? This problem is in a chapter called "Molecules," and it is part of a portion called Systems with two or more Atoms.

1. Write down all the possible Burgers vectors of perfect dislocations in an FCC metal. 2. For an a/2[1 dislocation line moving on a (11-1) plane in an FCC crystal, what are the line directions (in Miller indices) if the dislocation is of (i) pure screw and (ii) pure edge character? For an a/2[1 dislocation line moving on a (11-1) plane in an FCC crystal, what are the line directions (in Miller indices) if the dislocation is of (i) pure screw and (ii) pure edge character?

Below is the LCAO for the sp3 hybrid orbital. What is the value for the c²? (The answer mus be a number, not a fraction) Ya = C($25 +02p₂ +$2p, + $2p:) 2Px

P9E.11 (a) For a linear conjugated polyene with each of N carbon atoms contributing an electron in a 2p orbital, the energies E, of the resulting A molecular orbitals are given by: E, =a+2B cos- N+1 k=1, 2,.,N Use this expression to make a reasonable empirical estimate of the resonance integral B for the homologous series consisting of ethene, butadiene, hexatriene, and octatetraene given that t-n ultraviolet absorptions from the HOMO to the LUMO occur at 61 500, 46 080, 39 750, and 32 900 cm", respectively. (b) Calculate the T-electron delocalization energy, Egdo:= E, - n(a+ B), of octatetraene, where E, is the total T-electron binding energy and n is the total number of T-electrons. (c) In the context of this Hückel model, the molecular orbitals are written as linear combinations of the carbon 2p orbitals. The coefficient of the jth atomic orbital in the kth molecular orbital is given by: cN sin j=1,2.N jkn j=1, 2,.,N Evaluate the coefficients of each of the six 2p orbitals in each…

A K* and a CI- ion are separated by 0.52 nm. Find the Coulomb component of the binding energy at that distance. Give your answer in electron-volts. (Please include the appropriate sign.) A positive binding energy would mean the ions are unbound and a negative binding energy means they are bound. Note: For this homework problem, round your answer to 2 decimal places.

Q.1. The metals Cu and Pb have diamagnetic susceptibilities -9.63×10-6 and -1.58x10-5, respectively. Furthermore, Pb is a superconductor with T=7.2 K and Bo=800 G. Compare the magnetic energies of Cu and Pb in an external field of 500 G at 7.5 K and 0.1 K; assume the long-wire geometry with the field parallel to the wire. What is the principal difference in the free energy of the Pb sample at the two temperatures and in the presence of the field?
