Answer:
A. -0.003
B. 0.02
Explanation:
<u>Step 1:</u> identify the given parameters
Giving the following parameters
Wing area (S)= 1.5 m²
Wing chord (C) = 0.45 m
Velocity (V) = 100 m/s
moment about center of gravity(Mcg) = -12.4 N-m
at another angle of attack, L = 3675 N and Mcg = 20.67 N-m
<u>Step 2:</u> calculate the value of the moment coefficient about the aerodynamic center (Cmcg)
= 6125 N/m²
= -0.003
at zero lift
<u>Step 3</u>: calculate coefficient of lift
Cl = L/q*s
Cl = 3675/6125*1.5 = 0.4
<u>Step 4:</u> calculate the location of the aerodynamic center
New moment coefficient about the aerodynamic center (Cmcg):
= 0.005
=0.02
the location of the aerodynamic center = 0.02
Answer:
Option (B) increases only
Explanation:
An isolated system, in thermodynamics is defined as the system which does not allow the exchange of both the energy and mass in between the system and the surrounding.
In any practical thermodynamic process, the entropy of an isolated system increases only as the system can neither exchange energy nor mass but can generate the randomness in the molecules inside the system thus increasing its entropy up to the equilibrium point at which it reaches its maximum point.
The separation and purification process is used for DEVELOPING VACCINES. The development of vaccines must follow strict guidelines.
A vaccine is a biological preparation used to protect against harmful diseases (e.g., viruses) in a simple and safe manner.
Vaccine purification is a strict process consisting of clarification, concentration and chromatography in order to separate the extract that contains the active principle of the vaccine.
The techniques used for vaccine filtration include membrane filtration, depth filtration and centrifugation.
