Question
Which statement best summarizes Torricelli's explanation for the limit to which was possible to lift water using the pumps in use in sixteenth century Firenze? b. The attraction of the liquid for the walls of the cylinder draw the liquid up d. Suction is only sufficiently strong to draw any liquid to a height of 34 fee a. The weight of the air pushes the water up the cylinder until the weight the lifted water exactly matches that of the air. the tube until gravity overcomes the effect. The pumps were not sufficiently well enginecred. c. Tidal forces are particularly strong in cylindrical containers. e. A compound is 43.1%iron by mass. What mass of the compound contains 150 a. 212 lbs b. 348 lbs c. 294 lbs d. 361 lbs e. 64.7 lbs Dimethyl sulfate is 4.79% hydrogen, 25.4% sulfur, 19.0% carbon and 50.7% lbs of iron? oxygen. In synthesizing this compound, how much sulfur is needed to combine a. 1500 kg b. 6,670 kg.,0 kg d. 7,950 kg c. 283 kg with 1,500 kg of hydrogen? oncluded about the ratio of two quantities that are directly proportional? a. The ratio is a constant. The ratio is an irrational number c. The ratito becomes larger as the quantities become larger. is greater than one ratio beco The ratio becomes greater as the quantities become smaller. c.Explanation / Answer
Percentage of iron=43.1
Mass of iron=150 lb
Let mass of compound be m
0.431*m=150
m=150/0.431=348 lbs
Correct option is b
Mass of hydrogen=1500 kg
%age of hydrogen=4.79
%age of sulfur=25.4
Mass of sulfur required=1500*25.4/4.79=7954 kg
Correct option is d
The ratio is a constant. Correct option is a
