Using Bernoulli's equation Calculate the percentage increase in the speed of the air on the upper surface of the wings relative to the lower surface, if aircraft mass is 3.3×10^5kg, Total wing area is 500m^2 ,Flight level speed of 9600km/h and density of air is 1.2kgm^-3??​

Copper has free electrons per cubic meter. a 71.0-cm length of 12-gauge copper wire that is 2.05 mm in diameter carries 4.85 a of current. (a) how much time does it take for an electron to travel the length of the wire? (b) repeat part (a) for 6-gauge copper wire (diameter 4.12 mm) of the same length that carries the same current. (c) generally speaking, how does changing the diameter of a wire that carries a given amount of current affect the drift velocity of the electrons in the wire?
