A demographic transition model is used to help describe the relationship between the population of an area and the economyAs early as the 1920's, it was observed that was observed that in countries with high standards of Livingthe population grew at a slow rate while in countries with low standards of living, the population grew more rapidly. This observation resulted in the concept of demographic transition, which is a series of stages that a country goes through while changing from a non-industrial to an industrial country The decline in death rate and birth rate that occurs during the demographic transition may transform the age structure within a country. Consider the population pyramids seen hereExplain how can tell that stage is typical of the hunting gathering societies previously viewed in the demographic transition model ฮ There is a declining birth rate and death rate. B There is a high birth and death rate and short life expectancy There is a high birth rate and low death rate with little population growth D) The death rate is high for the younger segment of the population so few reach old age

Ajet plane has a sound level of 120 db at a distance of 60 m. what is the q23. sound level at a distance of 6.0 km? (60)2 (6000)? om solution 80db db, hint: 16x assume ultrasound waves travel through the body of an animal at 1540 q24. m/s. if a 30,000 hz signal were reflected off a portion of a heart which was moving toward the source at 3 m/s, what frequency signal would return to the stationary source? solution 30.117hz
