Two thin converging lenses A and B have focal lengths fA and fB, respectively. Lens A has a shorter focal length than Lens B. A collimated laser beam travels down an optical axis from left to right. How must the two lenses be arranged on the optical axis so that the laser beam emerges from the pair of lenses collimated with an increased diameter

An air-standard stirling cycle operates with a maximum pressure of 600 psia and a minimum pressure of 10 psia. the maximum volume of the air is 10 times the minimum volume. the temperature during the heat rejection process is 100°f. calculate the specific heat added to and rejected by this cycle, as well as the net specific work produced by the cycle. use constant specific heats at room temperature. the properties of air at room temperature are r

Ahypothesis is? close agreement by competent observers of observations of the same phenomena. a guess that has been tested over and over again and always found to be true. an educated guess that has yet to be proven by experiment. the long side of a right triangle. a synthesis of a large collection of information that includes guesses.
