Ultrasound with a frequency of 4.40 MHz can be used to produce images of the human body. If the speed of sound in the body is the same as in salt water, 1.30 km/s, what is the length of a 4.40-MHz pressure wave in the body

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
