Exp 2- 25.00 mL of an unknow liquid were measured three times. The mass of each of the 25.00 mL samples were 36.137, 36.241, 36.098 g. Calculate the density of each sample and average value of the density. - 1.) 36.137 g/ 25.00 mL= 1.445 g/mL 2.) 36.241 g/ 25.00 mL= 1.450 g/mL 3.) 36.098 g/ 25.00 mL= 1.444 g/mL Average 1.445+ 1.450 + 1.444= 4.339 4.339/3= 1.446 g/mL Exp 2- Consider a stone column 3.00 ft in diameter and 10.00 ft high. What is its mass in pounds if the density is 3.50 g/...

NIFE AERO QUESTIONS AND ANSWERS RATED A+ What is a vector? direction and magnitude What is air density? Total mass of air particles per unit volume. m/v What is a moment? Force that is moved some distance. What are the requirements for an airplane to be in equilibrium flight? Sum of all forces and all moments around the center of gravity are equal to 0 Can equilibrium flight be achieved in a turn? No. Acceleration is occurring.

ASPE CPD Study Questions AH Latest Version Graded A+ What is specific gravity in relation to water? Specific gravity is a dimensionless number that compares the density of a substance to the density of water, helping to determine how heavy a substance is relative to water. How is specific gravity measured? Specific gravity is measured using a hydrometer, which floats in a liquid, providing a reading based on how deep it sinks. Why is specific gravity important in water quality te...

NIFE Aero Latest Version with Certified Solutions Define Vector A quantity that expresses both magnitude and direction. A vector quantity is represented by an arrow that displays direction and has a length proportional to magnitude Moment Force applied at some distance from an axis or fulcrum F x d (Distance: from the point of rotation that is perpendicular to force, "moment arm") Equilibrium Flight When the sum of all FORCE and all MOMENTS around the COG are equal to zero ...

T/F: Current exists in an ideal capacitor only when its voltage is changing True T/F: In a series capacitor circuit, the largest value of capacitance will have the smallest amount of voltage dropped across it. True T/F: In a series capacitor circuit, the largest value of capacitance will have the largest share of total charge on its plates False T/F: Magnetic lines of force never cross one another True T/F: Current flowing through a conductor creates a magnetic fi...
