Question 7 of 36 > >> Question 7 2 points Save Answer An aircraft moves through stationary air, producing just enough lift force to balance the weight of the aircraft. The weight of the aircraft is then increased by 10%. How much must the speed of the aircraft be increased (as a percentage) to provide just enough lift for this new weight? Give your answer to 2 decimal places. Assume that the aircraft remains at the same angle relative to its motion and that the Lift Coefficient and density are constant.

Question 9 of 36 > >> Question 9 2 points Save Answer Aluminium can be a good material for pressure vessels that require high-strength and corrosion resistance. Solution hardening is often used to modify the strength of aluminium by adding other elements, such as magnesium. If the concentration of magnesium is increased, which of the following most accurately describes the change in strength of the new aluminium alloy? O Strength increases for small concentrations but subsequently decreases when the concentration gets higher. O Strength increases in direct proportion to the increase in concentration of magnesium. O Strength increases as magnesium is added and at an increasing rate as the concentration is increased further. O Strength increases as magnesium is added but at a lower and lower rate as the concentration increases further. ...A Moving to another question will save this response. Question 9 of 36 > >>
