The figure shows a plot of potential energy U versus position x of a 0.250 kg particle that can travel only along an x axis under the influence of a conservative force. The graph has these values: UA = 9.00 J, UC = 20.0 J and UD = 24.0 J. The particle is released at the point where U forms a “potential hill” of “height” UB = 12.0 J, with kinetic energy 8.00 J. What is the speed of the particle at (a)x = 3.50 m and (b)x = 6.50 m? What is the position of the turning point on (c) the right side and (d) the left side?

The figure shows an approximate plot of stress versus strain for a spider-web thread, out to the point of breaking at a strain of 2.05. The vertical axis scale is set by a = 0.130 GN/m2,b = 0.460 GN/m2, and c = 0.840 GN/m2. Assume that the thread has an initial length of 0.780 cm, an initial cross-sectional area of 8.00 × 10-12 m2, and (during stretching) a constant volume. The strain on the thread is the ratio of the...

The Lennard-Jones potential energy, U(x), is a function of "x" the distance between a pair of molecules. It is frequently called the van der Walls potential between molecules for dipole-dipole interactions. The potential is U(x) = C12/ x^12 - C6/x^6             [1] Here we assume for water molecules: C12 = 9.5 x 104" J•m12 C6 = 1 x 10-76 J•m6. (a) What is the separation distance (Xs) between two water molecules where the applied force (F) to pull the molecules apart...

The Lennard-Jones potential energy, U(x), is a function of “x” the separation distance between a pair of atoms in a molecule. It is frequently called the van der Walls potential between atoms for dipole-dipole interactions. The potential is U(x) = C12/ x12 - C6/x6,                                                                    [1] Where C12 = 1.51 x 10-134 J∙m12 C6 = 1.01 x 10-77 J∙m6.
