Both Technician A and B are correct because While raising the coolant's boiling point, it lowers the coolant's freezing point.
In order to help control engine temperature, antifreeze is a tinted liquid that you add to your radiator along with water. Ethylene glycol, which lowers water's freezing point and increases its boiling point, is a key component of the substance. By doing this, you can avoid having your radiator's water freeze, boil, or evaporate. At 212°F, water begins to steam. The boiling point of conventional ethylene glycol antifreeze is raised to 223°F by combining it with water in a 50-50 ratio; this temperature is close to that of an engine. Antifreeze is an additive that lowers a liquid's freezing point that is made of water. A mixture of antifreeze is used to lower the freezing point for cold environments and raise the boiling point for higher coolant temperatures.

What is resistance ?
Electrical resistance, or resistance to electricity, is a force that opposes the flow of current. It acts as a gauge for the difficulty of current flow in this way. Ohms () are used to express resistance values. Electrical will flow from to low when two terminals have an electron difference. That flow is countered by resistance. The current decreases as resistance increases. On the other hand, the current increases as the resistance decreases.

This is not the right conclusion, no. Temperature is one of many factors that might induce warping, but this is not the only one. Warping can also be influenced by other elements like humidity.
What is temperature ?
The physical concept of temperature indicates in numerical form how hot or cold something is. A thermometer is used to determine temperature.

A rocket launches with a constant acceleration of a all the way to outer space, straight up. You are not sure what a is, but it is relative small (between 2 ft/s2 and 10 ft/s?). Ignore compressibility effects. The atmosphere follows a standard temperature and pressure profile (so you can compute the density ratio directly from 0). a. As a function of a, at what altitude will the rocket experience maximum dynamic pressure q? b. What is that pressure as a function of a? c. How does the answer vary with acceleration?
The abbreviation "Maximum dynamic pressure" is Max Q. It occurs when the rocket or spacecraft is under "maximum mechanical stress" during the launch.
Which simply means that the rocket is experiencing significant physical pressure as a result of traveling through the atmosphere's air at a very high speed. After the rocket has been launched for around 60 seconds and has reached an altitude of 11 km, Max Q occurs. Max Q for the Space Shuttle happens at a similar altitude, about. The maximum dynamic pressure, or Max Q, is reached when the dynamic pressure reaches its greatest level due to the increasing velocity.

A wide range of Zener voltages, some of which are even variable, are used in the manufacture of Zener diodes. The reverse conduction occurs in some Zener diodes with sharp, highly dopped p - n junctions and low Zener voltages; in these cases, the Zener effect, named after Clarence Zener, is caused by electron quantum tunneling in the small gap between the p and n regions.
Avalanche breakdown also occurs during the operation of diodes with higher Zener voltages, which have a more gradual junction.

Consider a unity-feedback control system with the open-loop transfer function G(s) = K/ (s(s^2+s+4)
A) Determine the value of the gain K such that the phase margin is 50∘?
B) What is the gain margin for this case?
A) The phase margin is given by PM = -tan-1 (ωc/ζ) - 180
where ωc is the critical frequency and ζ is the damping ratio.
For a phase margin of 50°, we have
-tan-1 (ωc/ζ) = -130°
or
ωc/ζ = tan 130°
Now, the damping ratio is given by
ζ = -log(GM)/(√π2 + log2(GM))
where GM is the gain margin.
Substituting for ζ in the above equation, we get
ωc = tan 130° × -log(GM)/(√π2 + log2(GM))
Solving for GM, we get
GM = exp(-tan 130° × √π2 + log2(GM))
Now, we can calculate the gain K from the open-loop transfer function G(s) = K/ (s(s2 + s + 4))
K = GM × (s2 + s + 4)
Substituting for GM, we get
K = exp(-tan 130° × √π2 + log2(GM)) × (s2 + s + 4)
Hence, the value of the gain K such that the phase margin is 50° is given by
K = exp(-tan 130° × √π2 + log2(GM)) × (s2 + s + 4).

Explanation:
1. Consider the supply contract problem scenario that we discussed in class (and in Chapter 4). That is, the seller (supplier) is MTO; the seller pays a fixed cost of $100,000 to produce, and its per unit production cost is $35; the buyer pays the seller $80 per item purchased, and sells the items, for which there is a demand, for $125; the residual price is $20. As discussed, the globally optimal solution which maximizes the combined expected profit, is for the buyer to purchase Q* = 16,000 items. This results in a combined expected profit of $1,014,500. Suppose that the buyer and seller do not share any information beyond that given in the following contract: Suppose that the buyer and seller have a revenue sharing contract with Chew being the new cost per unit for the buyer in exchange for x% revenue sharing. Suppose Chew = CM = 35. Does there exist a value of x that will both: yield both the maximum combined expected profit and equally split it between the buyer and the seller? If so, determine this value of x. If not, explain why no such value exists.
No, there is not a value of x that will yield both the maximum combined expected profit and equally split it between the buyer and the seller. This is because the maximum combined expected profit ($1,014,500) is not evenly divisible by two. Therefore, the buyer and seller cannot split the expected profit equally. The theory at play here is the game theory.
What are the basics of game theory in economics?The study of an intuitive decision in which the outcome for each respondent or "player" is influenced by the actions of everyone else is known as game theory.

Explain on a structural basis the differences in the glass transition temperature of polyethylene ( =-140°C), polyvinylchloride (T-87 C), and polysityrene (Tg= 100 c)
The "glass transition" temperature is the point at which it happens. For instance, low-density polyethylene has a glass transition temperature, or Tg, of about 100°C.
He claims that the fact that the Tg of PVC/CF composite is higher (86.7 °C) than the Tg of pure PVC (76.8 °C) indicates that there is a physical interaction between the polymer and the CF surface, which reduces chain mobility and free volume and increases Tg. Pressure and free volume. Increased surrounding pressure causes a decrease in free volume, which ultimately results in increased Tg. The glass transitioning temperature of polymers is also significantly influenced by other elements such as branching, alkyl chain length, bond interaction, flexibility of the polymer chain, film thickness, etc.
