Answer:
a. State the functions of the followingsa. Commutator:
the commutator reverses the current direction with each turn serving as a mechanical rectifier to convert the alternating current from the windings to unidirectional direct current in the external load circuit.
b. Armature core
Armature core is a physical structure made up of silicon steel stampings. The core is laminated to keep iron losses low. Armature winding is the main current carrying winding where we either provide(electric supply to motor) or extract e.m.f(collect electric power from generator).
c. Field system
The field winding basically form an electromagnet, that produces field flux within which the rotor armature of the DC motor rotates, and results in the effective flux cutting
d. Brushes
The function of brushes is that the brushes conduct current between stationary wires and moving parts of the electric Generator.
e. Armature winding
The winding wound on the core is given current through a DC supply. This current-carrying winding as under the influence of the magnetic field develops a force that develops a rotational torque. This torque enables the machine to rotate.

Find the mean deviation of the set of numbers
(a) 12, 6, 7, 3, 15, 10, 18,5
Answer:
4.25
Explanation:
The mean deviation is how far, on average, all values are from the middle. To do that, we subtract each element from the mean of the elements, take their absolute values, and then divide by the number of elements in the set. Here's the formula: [tex]\sum\frac{|x-\mu|}{n}[/tex]
Here the mean is 9.5, the count n = 8, so the mean deviation is 4.25

Explanation:
Over 30 day period, a lake surface area is 1260 acres. The inflow is 36 cfs, thee outflow is 30 cfs. Seepage loss is 1.5 in. The total precipitation is 4.0 in. Evaporation loss is 6.0 in. Determine the water level change (inch) for the lake during this period.
Answer:
-0.1 inches
Explanation:
The net inflow is ...
36 cfs -30 cfs = 6 cfs
The number of seconds in 30 days is ...
(3600 s/h)(24 h/da)(30 da) = 2,592,000 . . . . seconds/(30 days)
Then the volume of inflow is ...
(6 ft^3/s)(2,592,000 s) = 15,552,000 ft^3
The number of square feet in 1260 acres is ...
(1260 ac)(43560 ft^/ac) = 54,885,600 ft^2
So, the increase in depth due to the inflow is ...
(15,552,000 ft^3)/(54,885,600 ft^2) ≈ 0.283353 ft ≈ 3.4002 in
__
The net change in water level is then ...
inflow - seepage + precipitation - evaporation
3.4 in -1.5 in +4.0 in -6.0 in = -0.1 in
The water level change in the period is -0.1 inch.
Two students are discussing weathering and erosion factors. Leah says that both weathering and erosion involve wind, water, and ice. Justin says that only weathering involves ice, and that erosion involves plants and animals. Who is correct?
A. Justin, because plants cause erosion too.
B. Justin, because erosion does not involve ice.
C. Leah, because she forgot to mention plants and animals.
D. Leah, because glaciers are ice that cause erosion too.
Answer: Justin is false and it is both bottom because plants and animals are helpless to erosion and we cause it by deforestation and weather does too
Explanation:
Justin, because plants cause erosion too factors. This was the statement are the correct. Thus, option (a) is correct.
What is erosion?The geological process through which earthen elements are worn down and transferred by wind and water or water is known as erosion. The migration of nanoparticles away from their origins is referred to as erosion. Erosion is the loss of dirt, rock, or dissolved substances by surface processes.
According to the two students are the different in the studies. There was the based on the Leah are the said on the different in the concept and the Justin said into the different in the concept are the perception of the topic are the different. Justin was the correct because plants are the cause of erosion too factors.
As a result, the Justin, because plants cause erosion too factors. Therefore., option (a) is correct.

PDC Bank is working on creating an AI application that enables customers to send SMS to the AI application to allow banking activities from their registered ID. Jane, the project engineer, has taken bank customer data from the last few years from the server and is using it to train the ML to recognize and authenticate actual users and to ensure unauthorized users are barred from entering the application. Suppose the AI application has been compromised, and the reason has been identified as compromised data being used to improve the ML accuracy. What kind of attack is the PDC Bank application subjected to?
The kind of attack that the PDC Bank application is subjected to due to compromised data is: Adversarial artificial intelligence
Adversarial artificial intelligence is a form of attack on a neural network where a wrong algorithm is entered into the system to deceive the end user.
The aim of this machine learning method is to deceive the end user.
This is what happens to the PDC Bank when its data was compromised in the course of improving the machine learning accuracy.

Describe two fundamental reasons why flexural strength should depend on porosity
Answer: The elastic modulus and flexural strength are found to decrease with increased porosity. Fractography studies have been undertaken to identify the role of the pores on the fracture path. The deflection and cracking behavior of concrete structure depend on the flexural tensile strength of concrete. Many factors have been shown to influence the flexural tensile strength of concrete, particularly the level of stress, size, age and confinement to concrete flexure member, etc.
