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: Yes
Explanation:
While handling and managing offices, means a lot of different tasks, including files,overseeing supplies, running the mailroom and worker productivity, the space planner work is to specifically focus on managing the space within your office building. When it comes to all room within each wing of each floor, the space planner's work is to layout and optimize the design in order to maximize productivity and also keep the employees happy.
Work of the space ePlanner includes all those in listed above in the question.
Answer:
- |z*| = r , ∠(z*) = -∅
- |z²| = r² , ∠(z²) = 2∅
- |jz| = r , ∠(jz) = ∅
- |zz*| = r² , ∠(zz*) = 0
- |z/z*| = 1 , ∠(z/z*) = 2∅
- |1/z| = r ⁻¹ , ∠(1/z) = -∅

1.) The * mean you take the conjugate of the value. This means you change the sign of the imaginary part, so if it's positive, turn it negative and vice versa.
2.) The magnitude with an exponent can have the exponent moved outside the magnitude. |zⁿ| = |z|ⁿ
The angle multiplies with its exponent instead. ∠zⁿ = n∠z
3.) This part is just testing if you can convert the number using the eulers formula and convert back.
The magnitude could be found using the distance formula. √(R² + I²)
The angle could be found using tan⁻¹(Imaginary/Real).
4.) Magnitude of a product could be split up. |zv| = |z|·|v|
Angle of a product could be splitted up and added. ∠(zv) = ∠z + ∠v
5.) Simplify it first using some algebra and use the euler's identity to identify the magnitude and angle. It takes in a form like this:
A is your magnitude, ∅ is your angle.
6.) Same rule as part 2
Answer:
Explanation:
For an isolated system (one that does not exchange matter of energy with its surroundings) entropy tends to raise.
The entire universe might be considered as an isolated system, and thus the entropy of the universe tends to rise and it never lowers.
Note that this is for isolated systems, not any systems.
A certain system might have its entropy go down, but for that it must exchange energy with its surroundings, and the entropy of the surroundings will raise. The change of entropy of the surroundings plus the change of entropy of the system (remember their signs) will always be positive.
Answer:
k = 0.1118 per min
Explanation:
Assume;
Initial number of bacteria = N0
Number of bacteria IN 'T' time = Nt
So,
k = 0.1118 per min
