Choose the options below that are true for the entropy of a substance. Select all that apply: Heavier atoms possess greater entropy at a given temperature than lighter atoms. The weight of an atom has no effect on entropy. Molecules with greater numbers of atoms are associated with lower entropy. The entropy of a substance is influenced by the structure of the particles that comprise the substance.

An average person generates heat at a rate of 84 W while resting. Assuming one-quarter of this heat is lost from the head and disregarding radiation, determine the average surface temperature of the head when it is not covered and is subjected to winds at 10°C and 29 km/h. The head can be approximated as a 0.2-m-diameter sphere. Assume a surface temperature of 15ºC for evaluation of μs. The properties of air at 1 atm pressure and the free stream temperature of 10°C are k

1. What is the linear distance traveled in one revolution of a 9 in diameter wheel?
2. An industrial water shutoff valve is designed to operate with 15 Ib of effort force. The valve will encounter 155 Ib of resistance force applied to a 0.85 in diameter axle. What is the actual mechanial advantage of the sytem?
3. If the diameter of the wheel is 10.5 inches, what is the efficiency of the wheel and axle system?
4. A block and tackle system with 8 supporting strands is used to lift materials in a manufacturing facility. The motor being used to wind the cable in the pulley system can provide 200 Ib of force. What is the ideal mechanical advantage of the pulley system?
5. Ideally what is the maximum weight of materials that can be lifted?

EMB agar is a medium used in the identification and isolation of pathogenic bacteria. It contains digested meat proteins as a source of organic nutrients. Two indicator dyes, eosin and methylene blue, inhibit the growth of gram-positive bacteria and distinguish between lactose fermenting and nonlactose fermenting organisms. Lactose fermenters form metallic green or deep purple colonies, whereas the nonlactose fermenters form completely colorless colonies. EMB agar is an example of which of the following? A selective medium, a differential medium, and a complex medium
