Faster air movement over an airfoil creates a _________ pressure field, which in turn allows lift.
a
Higher
b
Lower
Hai
Your answer will be A.
If you lower the Air Pressure your Object will Float Down ward. The Air Pressure allows it to Fly.
The pressure field created by faster air movement over an airfoil is; A: higher
What is pressure field?When the air hits the front of the wing, the air will flow in a steeper curve upward, than the bottom wing flow which will lead to the creation of a vacuum on top of the wing that pulls more air towards the top of the wing.
Finally, this air above does the same thing but it will move faster as a result of the vacuum pulling it in, and as such the vacuum now lifts the wing. Thus, Faster air movement over an airfoil creates a higher pressure field.

An automobile having a mass of 1100 kg initially moves along a level highway at 120 km/h relative to the highway. It then climbs a hill whose crest is 80 m above the level highway and parks at a rest area located there. Use a reference with kinetic and potential energy each equal to zero for the stationary highway before the hill. Let g = 9.81 m/s^2.
For the automobile, determine its change in kinetic energy and its change in potential energy, both in kJ. For the automobile, determine its change in kinetic energy, in kJ.
a. -8594
b. -663.1
c. -6.63x10^5
d. 663.1
Answer:
[tex]-6111.11\ \text{kJ}[/tex]
[tex]863.28\ \text{kJ}[/tex]
Explanation:
m = Mass of automobile = 1100 kg
v = Velocity of car = 120 km/h = [tex]\dfrac{120}{3.6}\ \text{m/s}[/tex]
h = Height of hill = 80 m
g = Acceleration due to gravity = [tex]9.81\ \text{m/s}^2[/tex]
Change in kinetic energy
[tex]KE=\dfrac{1}{2}m(u^2-v^2)\\\Rightarrow KE=\dfrac{1}{2}\times 1100\times (0-(\dfrac{120}{3.6})^2)\\\Rightarrow KE=-611111.11\ \text{J}[/tex]
Change in kinetic energy is [tex]-6111.11\ \text{kJ}[/tex]
Change in potential energy is given by
[tex]PE=mgh\\\Rightarrow PE=1100\times 9.81\times 80\\\Rightarrow PE=863280\ \text{J}[/tex]
The change in potential energy is [tex]863.28\ \text{kJ}[/tex].
A communications system transmits a message. The probability that the message will be received is p. To be confident that a message is received at least once, the system transmits it n times. If a message is received, the receiver turns off and does not turn back on.
a. Assuming all transmissions are independent, what is the PMF of K, the number of times the pager receives the same message?
b. Assume p=0.8. What is the minimum value of n that produces a probability of 0.95 of receiving the message at least once?
Answer:
Follows are the solution to the given points:
Explanation:
In point a:
In the PMF of K, that pager receives its same message number of times, that is [tex]=\tiny \binom{n}{k}p^{k} (1-p)^{n-k}[/tex]
In point b:
The possibility of getting number of cultural at least once in x:
[tex]\to 1-P(\text{not receiving it at all})\\\\\to 1-(0.2)x\\\\\to 1-(0.2)x>0.95\\\\\to (0.2)x<0.05 \\\\[/tex]

Merchandise without an expiration date like electronics, tools and home goods typically have a longer
Answer:
Shelf life.
Explanation:
In Business, an inventory is a term used to describe a list of finished goods, goods still in the production line and raw materials that would be used for the manufacturing of more goods in a bid to meet the unending consumer demands.
Simply stated, an inventory can be classified into three (3) main categories; finished goods, work in progress, and raw materials.
An inventory is recorded as a current asset on the balance sheet because it's primarily the most important source of revenue for a business entity.
Also, the three (3) main cost concept associated with an inventory are;
1. First In First Out (FIFO).
2. Last In First Out (LIFO).
3. Weighted average cost.
Shelf life can be defined as a measure of the length of time that a particular product could be kept or stored without it getting bad or becoming unsuitable for use by the consumers. Thus, the shelf life of a product is largely dependent on its expiration date.
Hence, merchandise without an expiration date like electronics, tools and home goods typically have a longer shelf life.

Current is defined as the flow of electrical charge carriers, which are often electrons or electron-deficient atoms. The correct option is B.
What is current?Current is defined as the flow of electrical charge carriers, which are often electrons or electron-deficient atoms. The capital letter 'I' is a typical sign for current. The ampere, denoted by A, is the standard unit.
The relationship between current(I), resistance(R), and voltage(V) is written as:
V = IR
Given circuit has a total resistance of 10 ohms and 30 volts. Therefore, the total current that can be drawn from the circuit is,
30 volts = I × 10 ohms
I = 30/10 amp
I = 3 A
Hence, the correct option is B.

Under conditions for which the same room temperature is maintained by a heating or cooling system, it is not uncommon for a person to feel chilled in the winter but comfortable in the summer. Consider a room whose air temperature is maintained at 24ºC throughout the year, while the walls of the room are nominally at 26°C and 16°C in the summer and winter, respectively. The exposed surface of a person in the room may be assumed to be at a temperature of 32°C throughout the year and to have an emissivity of 0.90. The coefficient associated with heat transfer by natural convection between the person and the room air is approximately 2 W/m2·K.
Answer:
Hello your question is incomplete below is the missing part of your question
Determine Heat flux due to convection
answer : 16 w/m^2
Explanation:
Room temperature = 24°c
Room temperature during summer = 26°c
Room temperature during winter = 16°c
surface temp of person = 32°C
emissivity = 0.90
coefficient ( h ) = 2 W/m2.K
Determine Heat flux due to convection
Q" = h ( Δ T ) = coefficient * ( surface temp of person - room temperature )
= 2 * ( 32 - 24 ) = 16 w/m^2
