A) In the case of the Boundary Thickness Layer we use the given formula,
We know as well that,
Re = Número de Reynolds = 
Where,
U = velocity
= kinematic viscosity
For water, kinematic viscosity, 
So, 
B) For flat plate boundary layer. Given the Critical Reynolds Number.= 5*10^5 we know that is equal to Re above.
Thus,
C. Wall shear stress,
For water, dynamic viscosity, 
= 2.344*10^-5 lbf-s/ft^2

Answer:
C) The upward force of air resistance is greater with the note card causing it to reach the ground slower.
Answer:
The answer is 30 degrees.
Explanation:
The angle between the index and pinky fingers is 15 degrees.
Twice this angle is 2×15=30degrees.
A large force is required to accelerate the mass of the bicycle and rider. Once the desired constant velocity is reached, a much smaller force is sufficient to overcome the ever-present frictional forces.
