Physics
A particle, which is constrained to move along the x-axis, is subjected to a force in the same direction which varies with the distance x of the particle from the origin as F(x) = -kx + ax³. Here k and a are positive constants. For , the functional form of the potential energy U (x) of the particle is
Chemistry
The standard oxidation potentials, E⁰, for the half reactions are as Zn = Zn²⁺ + 2e^-; E⁰ = +0.76V Fe = Fe²⁺+2e; E⁰ = +0.41V The EMF for the cell oxidation: (a) –0.35V (b) +0.35V (c) +1.17V (d) –1.17V
