The experiment examines the electric filed on the surface of plates covered uniformly with low-conducting coating. Each plate has imbedded over the coating a pair of high conducting shapes (electrodes). You will experiment with three configurations: two circles, a circle and a segment, and two parallel segments. Required:
Give a list of the three configurations in descending order of electric field uniformity in the area between the electrodes, i. e. first is the configuration with most uniform electric field, last is the one with least uniform electric field.

In a load, the load is paralel to the shaft. n a. angular n b. thrust n c radial n d. none of the above

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?
