g Part A – Rectangular Electrodes Draw 6 to 9 electric field lines: starting at the positive electrode and stopping at the negative electrode, draw the electric field lines in such a way that they always intersect equipotential lines at right angles. The electric field lines should be drawn through the region between and the regions immediately above and below the electrodes. Use arrows along the electric field lines to show the direction of the electric field. Determine the magnitude of the electric field along the segment between the electrodes by using Equation 2-5 and the boundary conditions that the potential is either 0.0 V or 15.0 V at the negative or the positive electrode respectively. Find the average of the electric field values – this will be the average value of E that exists between the electrodes. Calculate the (sample) standard deviation, σ. Report the value of the electric field as:

Air is held within a frictionless piston-cylinder container, which is oriented vertically. the mass of the piston is 0.45 kg and the cross-sectional area is 0.0030 m2. initially (state 1) the pressure of the gas is sufficient to support the weight of the piston as well as the force exerted by the atmospheric pressure ( 101.32 kpa). the volume occupied by the air within the cylinder in state 1 is 1.00 liter. one end of a spring (with spring constant k = 1000 n/m) is attached to the top of the piston, while the other end of the spring is attached to a stage that can move vertically. initially the spring is undeflected and therefore exerts no force. then the stage is then moved quasistatically downward a distance of 10.0 cm, at which point the system reaches state 2. the piston-cylinder is not insulated; rather it remains in diathermal contact with the surroundings, which are at a constant temperature of 300 k. what is the change of pressure within the container?

Asolid round steel rod 6.25 mm in diameter and 375 mm long is rigidly bonded to the end of solid square brass rod 25 mm on a side and 300 mm long. the geometric axes of the bare are along the same line. an axial tensile force of 5.4 kn is applied at the extreme ends of the assembly. for steel e = 200 gpa and for brass e = 90 gpa. determine the total elongation for the assembly.
