3-102 One of the common procedures in fitness programs is to determine the fat-to-muscle ratio of the body. This is based on the principle that the muscle tissue is denser than the fat tissue, and, thus, the higher the average density of the body, the higher is the fraction of muscle tissue. The average density of the body can be determined by weighing the person in air and also while submerged in water in a tank. Treating all tissues and bones (other than fat) as muscle with an equivalent density of? muscle. Obtain a relation for the volume fraction of body fat xfat

100 kg of R-134a at 200 kPa are contained in a piston-cylinder device whose volume is 12.322 m3. The piston is now moved until the volume is one-half its original size. This is done such that the pressure of the R-134a does not change. Determine the final temperature and the change in the total internal energy of the R-134a.

Select all of the statements that are true for using the Digital Multi-meter: Group of answer choices For voltage and resistance measurements the test leads are placed in the same connections, common (or - ) and V (also Ω). There is a no difference between the DC and AC Voltage setting. To measure resistance the dial must be set to Ω. To measure DC voltage the dial must be set to V DC. It's OK to measure resistance with the circuit powered. You will get the correct measurement for resistance if the resistor is measured in a circuit.
