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.

Answer:
then back into the room
Explanation:
If you leave the door open, heat is merely recycled from the room into the refrigerator, then back into the room. A net room temperature increase would result from the heat of the motor that would be constantly running to move energy around in a circle.

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.

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.

An airline ticket counter forecasts that 220 people per hour will need to check in. It takes an average of 2 minutes to service a customer. Assume that arrivals are poisson distributed and service times exponentially distributed and that customers wait in a single queue for the first available agent.
a) If we want the average time a customer spends in the queue and in service to be 10 minutes or less, how many ticket agents should be on duty?
b) There airline wants to minimize the cost of idle ticket agents and the cost of customers waiting in the queue. The salary of a ticket agent is £12 per hour and the cost of a customer waiting in the queue is £5 per customer per hour. How many ticket agents should be on duty?
A) Number of agents required to achieve a wait time of 10 minutes or less = 8 agents
B) The number of agents required on duty to reduce cost = 9 agents
Given data :
Arrival rate of customers ( β ) = 220 per hour
Service rate ( mu ) = 60 minutes / 2 minutes = 30 customer per hour
utilization ( rho ) = 220 / 30 ≈ 7
at least 8 server personnel are required for stability of the queue
A) Determine the number of agents required to achieve a wait time of 10 minutes or less per customer
waiting time = 10 - 2 = 8 minutes
number of customers waiting ( ∝ ) = 7 and required server = 8
assuming Lq = 5.2266
Hence the waiting time in line = Lq / arrival rate
= 5.2266 / 220 = 0.0238 hour
= 0.0238 * 60 = 1.428 minutes
Since the waiting time ( 1.428 minutes ) is less than the original waiting time ( 2 minutes ) the number of agents that will achieve a wait time of 10 minutes or less is = 8 agents
B) Determine the number of ticket agents that should be on duty to minimize cost
salary of ticket agent = £12 per hour
cost of customer waiting in queue = £5 per hour per customer
i) When 8 agents are used
waiting time of customers = 0.0238 * 220 = 5.236
waiting cost for customers = 5.236 * 5 = £26.18
employee cost = 8 * 12 = £96
∴ Total cost = 96 + 26.18
= £ 122.18
ii) When 9 agents are used
waiting time for customers = 0.0074 * 220 = 1.628
Wq = 1.6367 / 220 = 0.0074
waiting cost for customers = 1.6367 * 5 = £ 8.1835
assuming Lq = 1.6367
employee cost = 9 * 12 = £ 108
∴ Total cost = 108 + 8.1835 = £ 116.18
From the calculations in ( i ) and ( ii ) the Ideal number of ticket agents that should be on duty to minimize cost should be 9 agents.
Hence we can conclude that A) Number of agents required to achieve a wait time of 10 minutes or less = 8 agents and The number of agents required on duty to reduce cost = 9 agents.
