Stepping voltages down to lower values is a common design challenge. A straight-forward solution to this is a voltage divider such as the circuit below. This designsynthesis has one degree-of-freedom. A measure (metric) of the effectiveness of the designis the efficiency of the circuit, defined as

Athermometer is removed from a room where the temperature is 70° f and is taken outside, where the air temperature is 10° f. after one-half minute the thermometer reads 60° f. what is the reading of the thermometer at t = 1 min? (round your answer to two decimal places.) ° f how long will it take for the thermometer to reach 30° f? (round your answer to two decimal places.)

Aspecimen of oil having an initial volume of 580cm^3 is subjected to a pressure increase of 4.0 mpa, and the volume is found to decrease by 0.40 cm^3. (a) what is the bulk modulus of the material? (b) what is the compressibility of the material?

Which form of cell division creates the sperm and egg, resulting in half of the chromosomes as the other cells?
