The essential assumption of airfoil being a flat plate with a zero angle of attack gives accurate results always.

The essential assumption of airfoil being a flat plate with a zero angle of attack gives accurate results always. Correct Answer False

This assumption is a first order approximation and the results become more accurate as the airfoil gets thinner and angle of attack approaches zero. It gives good results but the level of accuracy varies.

Mrs. Carson took a taxi to meet her three friends for lunch. They were waiting for her outside the restaurant when she pulled up in the car. She was so excited to see her friends that she left her tote bag in the taxi. As the taxi pulled away, she and her friends took notice of the license plate number so they would be able to identify the car when they called the taxi company.

#1 : The four women seem to agree that the plate starts out with the letter J.
#2 : Three of them agree that the plate ends with 12L.
#3 : Three of them think that the second letter is X, and a different three think that the third letter is K.

The four license plate numbers below represent what each of the four women thinks she saw. Which one is most likely the license plate number of the taxi?
