Q_1 From the Exhibit 4‚ U.S. Frasch Sulphur Industry Prices and Profitability‚ 1940-1967‚ we can get the information about the variations in the return on invested capital earned by the industry over the several decades. In sulphur industry‚ the return on invested capital was around 15% from 1940 to 1945. From 1946‚ rate of return began to increase dramatically‚ starting from 16.2 %( 1945)‚ and reached 33.8% in 1950. This high rate of return kept for couples of years (1951-1955)‚ ranging from 29%

through many physical changes. Children’s physical development is the outcome of countless orderly changes (McDevitt & Ormrod; 2010). There are certain age groups where children’s development will rapidly occur and then begin to slow down. Over the course of middle childhood children tend to show slow but steady gains in both height and weight (McDevitt & Ormrod; 2010). Throughout this essay we will look at the motor development of children in the middle childhood phase‚ the benefits physical activity
