A small, rigid object carries positive and negative 5.00 nC charges. It is oriented so that the positive charge has coordinates (-1.20 mm, 1.20 mm) and the negative charge is at the point (1.70 mm, -1.30 mm). (a) Find the electric dipole moment of the object. 1.45E-1 C · m î + C · m ĵ (b) The object is placed in an electric field $\vec{E} = (7.80 \times 10^3 \hat{i} - 4.90 \times 10^3 \hat{j})$ N/C. Find the torque acting on the object. N · m $\hat{k}$ (c) Find the potential energy of the object-field system when the object is in this orientation. 1.74E-7 J (d) Assuming the orientation of the object can change, find the difference between the maximum and the minimum potential energies of the system. 3.53E-7 J

What is the basic premise of situation strength theory? The strength of a situation determines whether our personality traits help or hinder us. When behavioural norms and standards are set and rigid, then people express themselves less freely. This means that personality is a bigger driver of behaviour in less structured settings. When behavioural norms and standards are set and rigid, then people rebel by expressing themselves more freely. This means that personality is a bigger driver of behaviour in highly structured settings. Our personality changes from one situation to the next; context is very important.

Two steel bars ($E_s = 200 \text{ GPa}$ and $\alpha_s = 11.7 \times 10^{-6}/^\circ C$) are used to reinforce a brass bar ($E_b = 105 \text{ GPa}$ and $\alpha_b = 20.9 \times 10^{-6}/^\circ C$). When the steel bars were fabricated, the distance between the centers of the holes that were to fit on the pins was made 0.5 mm smaller than the 2 m needed. The steel bars were then placed in an oven to increase their length so that they would just fit on the pins. Following fabrication, the temperature in the steel bars dropped back to room temperature. Determine the maximum load $P$ that may be applied to the brass bar if the allowable stress in the steel bars is 28.5 MPa and the allowable stress in the brass bar is 25 MPa The maximum load $P$ that may be applied to the brass bar is ____ kN
