12. How will the temperature change in a room with an open refrigerator door, once equilibrium is established
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.

Label the following statements as either T (true) or F (false).
1) For Propane (C3H8) burning with theoretical amount of air, the air-fule ratio on the mole basis is 5.
2) The enthalpy of any substance at the standard reference state is 0.
3) 180% of theoretical air is equivalent to 80% of excess air.
4) The conservation of mass principle requires that the total number of moles on each side of a chemical reaction is equal.
5) The adiabatic flame temperature of methane (CH4) burning with pure oxygen and theoretical amount of air is the same, all other conditions being the same.

A person has driven a car 180 m in 40 seconds. What is the car’s speed?
Answer:
4.5 m/s = 16.2 km/h
Explanation:
The speed is the ratio of distance to time:
speed = (180 m)/(40 s) = 4.5 m/s
A fully charged battery with 6 cells should indicate
Answer:
Battery Voltage
Voltage refers to the amount of electrical potential your battery holds. The standard automotive battery in today's vehicles is a 12-volt battery. Each battery has six cells, each with 2.1 volts at full charge. A car battery is considered fully charged at 12.6 volts or higher.

Help! Please explain also. Thank you
Answer:
17A) 52mm
17B) 132mm
17C) 67mm
18.) 34
Explanation:
For 17)
Each distance is determined by the total distances surrounding it. For example, 17A is 73mm - 21mm, which is 52mm.
For 18)
Set up the problem as an algebraic expression:
a + b + c + d = 115
Since you know 3 of the values, you can plug them in and subtract them from 115, which turns into 34.

Answer:
manager and supervisor
Explanation:
An unknown relative passes away and bequeaths upon you a small tract of land in Amherst. You decide to build a two-story storage facility to make the best of your bequest. But your self-storage dream is in jeopardy due to a 10 meter thick layer of soft clay (N<4) on the site. You put on your best geotechnical engineer hat, hire a driller to pull up some samples, and send them off to a lab for a consolidation test. The report indicates that the clay is a dark grey, slightly sweet, kaolinite blend with a cy = 1x10-7 mº/s, single-drained, and an ultimate settlement of 0.73 meters. It does not make financial sense to install deep foundations, so you are interested in how long it will take to consolidate the clay layer using a passive load.
How long will it take for settlements of 25, 50, and 65 cm to occur?
If you need to build within the next 12 months and have at least 65cm of settlement to be viable, does it make sense to proceed?
Answer: It does make sense, because I've been involved in these careers and have a long family line of them. And other questions?

Explanation:
Trues
a. State the functions of the followings
a. Commutator
b. Armature core
c. Field system
d. Brushes
e. Armature winding
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.

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.

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.

Lateral runout can be felt in the steering wheel even when the vehicle is
Select one:
a. At slower speeds
b. Just starting to move away from a stop
C. Just coming to a stop
d. Stopped
Lateral runout is felt in the steering wheel even at slower speeds. It leads to riding vibration and therefore poor ride quality.
Lateral runout refers to the side-to-side movement of the car's rotor as it rotates, which is caused by the off-center deviation of the rotor.
Lateral runout leads to riding vibration and therefore it is associated with poor ride quality.
Lateral runout can be properly quantified by using a dial indicator, which is a precision device used to measure linear displacements.

Explanation:
We assume the T flip-flop changes state on the rising edge of the clock input.
The first stage is connected to the clock. The second stage clock is connected to the inverse of the Q output of the first stage, so that when the first stage Q makes a 1 to 0 transition, the second stage changes state.
