Indicate whether the statement is true or false.
An on-line manufacturing work cell performs a series of four quality control tests on a manufactured product. Design a logic system that will simultaneously examine the results of all four tests and decide into which of the three output containers the piece will drop. A, B, C, and D are identified as four tests or inputs to the logic system. Bins #1, #2, and #3 are classified as outputs. If the product passes two OR three tests, Bin #1 will receive the part. If it passes one of the tests, Bin #2 will be open. Bin #3 accepts perfect units only.

A parallel plate capacitance transducer uses plates of area 500 mm which are separated by a distance of 0.2mm.
(i) Calculate the value of capacitance when the dielectric is air having a permittivity of 
.
(ii) A linear displacement reduces the gap length to 0.18mm. Calculate the change in capacitance.
(iii) Calculate the ratio of per unit change of capacitance to per unit change in displacement.
(iv) Suppose a sheet of mica 0.01mm thick is inserted in the gap. Calculate the value of original capacitance and change in capacitance for the same displacement. The dielectric constant of mica is 8 [C = A/d].
