D) resistance welding process.
Answers
Answer: Fusion
Explanation:
It has a tendency to fuse stuff
The correct answer is Option B).
GMA (MIG) welding is a fusion welding process.
Given data:
GMA (Gas Metal Arc) welding, also known as MIG (Metal Inert Gas) welding, is a fusion welding process. In GMA/MIG welding, a consumable electrode wire is used to create an electric arc between the wire and the workpiece. The arc heats and melts the base metals, and a shielding gas, typically a mixture of argon and carbon dioxide, is used to protect the weld pool from atmospheric contamination.
During the welding process, the molten electrode wire and the base metal fuse together to form a solid weld joint. This fusion of the materials is characteristic of fusion welding processes, where the base metals are melted to create the weld.
Hence, GMA/MIG welding is considered a fusion welding process.

after a car is jump started, you must unclip the jumper cable clips______.
Answers
Answer:
The correct answer is;
In the reverse order you connected them
Explanation:
The process of jump starting a car is as follows;
1) Connect the positive or red clip to the dead battery
2) Connect the other end of the positive or red clip to the other end of the live battery in the donor car
3) Connect the negative or black clip to the negative terminal on the live battery
4) Connect the other end of the negative or black clip to the bare metal (without paint coating) on the donor car
5) Start and idle the donor car
6) Test to see if there is electric power in the dead car. If yes, then start the dead car
By disconnecting in the reverse other, that is by first removing the black or negative terminal from the dead vehicle chassis, prevents short circuiting the system with the rest of the metals parts in vehicle body when a metal makes contact while the positive terminal is removed and the negative terminal is still on the chassis.

Air is contained in a piston-cylinder device at 9 bar and 927˚C, and occupies a
volume of 0.8 m3. The air undergoes an isothermal process until the pressure is
reduced to 4.5 bar. The piston is now fixed in place and not allowed to move while
a heat transfer process takes place until the air reaches 27˚C. Assume the air to be
a perfect gas. Take cp=1.005 kJ/kg∙K and cv=0.718 kJ/kg∙K.
(a) Calculate the final volume and final pressure of the air.
(6 marks)
(b) Determine the change in internal energy of the air, the work done
by the air and the total heat transferred.
Answers
a) Note that the final volume of the air is also 1.6 m3, and the final pressure is 4.5 bar; and
b) the change in internal energy of the air is 0 kJ, the work done by the air is 0.966 kJ, and the total heat transferred is 487.7 kJ.
What is the rationale for the above response?To solve this problem, we can use the ideal gas law and the first law of thermodynamics.
(a) To determine the final volume and final pressure of the air, we can use the ideal gas law, which states that:
P1V1/T1 = P2V2/T2
where P1, V1, and T1 are the initial pressure, volume, and temperature, respectively, and P2, V2, and T2 are the final pressure, volume, and temperature, respectively.
We can first use this equation to determine the final volume of the air during the isothermal process:
P1V1/T1 = P2V2/T2
(9 bar)(0.8 m3)/(1200 K) = P2V2/(927 K)
V2 = (9/4.5) * (0.8 m3)
= 1.6 m3
Now, we can use the ideal gas law again to determine the final pressure of the air during the isothermal process:
P1V1/T1 = P2V2/T2
(9 bar)(0.8 m3)/(1200 K) = (P2)(1.6 m3)/(1200 K)
P2 = (9 bar)(0.8 m3)/(1.6 m3)
= 4.5 bar
During the subsequent heat transfer process, the piston is fixed in place, which means the volume of the air remains constant at 1.6 m3.
Therefore, the final volume of the air is also 1.6 m3, and the final pressure is 4.5 bar.
(b) To determine the change in internal energy of the air, the work done by the air, and the total heat transferred, we can use the first law of thermodynamics, which states that:
ΔU = Q - W
where ΔU is the change in internal energy, Q is the heat transferred, and W is the work done.
During the isothermal process, the temperature of the air remains constant at 927 K, which means the internal energy of the air does not change:
ΔU = 0
During the isothermal process, the work done by the air is:
W = -P1V1 ln(P2/P1)
= -(9 bar)(0.8 m3) ln(4.5/9)
= 0.966 kJ
During the subsequent heat transfer process, the air is heated from 927 K to 300 K, which means heat is transferred into the air:
Q = m cΔT = (P2V2/R) cΔT
= (4.5 bar)(1.6 m3)/(287 J/kg∙K) (1.005 kJ/kg∙K) (927 K - 300 K)
= 487.7 kJ
Therefore, the change in internal energy of the air is 0 kJ, the work done by the air is 0.966 kJ, and the total heat transferred is 487.7 kJ.

How is law of resistivity represented?The Law of resistivity can be mathematically represented as:
R = ρ × (L / A)
Where:
R is the electrical resistance of the conductor,
ρ (rho) is the resistivity of the material,
L is the length of the conductor, and
A is the cross-sectional area of the conductor.
The resistivity (ρ) is a characteristic property of a material that quantifies its ability to resist the flow of electric current. It depends on the nature of the material, its temperature, and sometimes its purity. Resistivity is measured in ohm-meters (Ω·m).

 A game consists of a 3-card hand. What are the chances of have a pair (same face-value) in a hand, given the first two cards are not a pair?
Answers
Answer:13
Explanation:
The probability of getting a pair (but NOT three of a kind) in three-card poker would be 3744/22100 = .1694+.
Obviously any of the three cards NOT in the pair is equally likely to have been dealt to you last. So in the 1/3 of cases where the non-paired card was dealt last, then your criteria were met: first you got a pair, then you got something outside the pair. 1/3 of the above value is 1248/22100 = 0.05647+.
How did I get the 3744/22100 figure?
13 (number of ranks the pair could be in) TIMES 6 (number of ways to have two of the four cards within the paired rank) TIMES 48 (number of ways to have one of the other cards outside the pair) DIVIDED BY 22100 (which is 52 choose 3, the number of unique three card poker hands.)

If humans can't physically evolve to ever have wings, could it be scientifically possible to engineer wings?
I know it won't potentially happen anytime soon, of course, but knowing that technology is constantly advancing and humans are constantly adapting to new environments, could at some point a form of wing that is neurologically controlled without need for human input, that could have a power input that constantly charges be possible?
I know humans are weighty and don't have the same bone/muscle/organ structure as a bird or bug, not by any means, but given hang gliders already give the ability to glide and there's wing-suits, it's proven humans can sustain in the air for considerable amounts of time. I know it's also due to how high up the starting point of gliding is, and gliding is a much different thing to actual flight.
How many years, do you suppose, that it'd take in order for technology to advance to have a battery that could charge enough to generate lift for the human form, and is light enough to not add too much more weight to the wing/body?
Of course deeper science is needed, but I figure it's worth contemplating and talking about as opposed to being outright shut down, right? Anything's worth theorizing to potentially have such a thing put into practice, anyway. Plus, I haven't seen a whole lot of research going into such a technology anymore, which is sad because it's been a near life-long dream to have wings and fly as a winged human.
I know it's just a dream, but I also know it could be possible. Definitely not in my lifetime, though. Also, I love seeing some of the arguments and theories for such a thing.
