technician a says that oat coolants are based on propylene glycol. technician b says that hoat stands for hybrid organic acid technology. which technician is correct?
Technician A and B both are correct. An internal combustion engine and one or more electric motors, which utilise energy stored in batteries, work together to power hybrid electric cars.
The battery of a hybrid electric car cannot be charged by plugging it in. Instead, the internal combustion engine and regenerative braking are used to charge the battery. Instead of the usual 3.0-4.20V/cell, the battery operates at 30-80% state-of-charge (SoC), or around 3.5-4.0V/cell for Li-ion. When the gasoline engine isn't running, hot coolant is typically kept in an insulated coolant storage tank to heat the passenger compartment. Additionally, the air conditioner compressor will be electric so that it operates even when the gasoline engine is off; servicing this will call for special oil.

Because its gain is always negative, the inverting operational amplifier is essentially a constant or fixed-gain amplifier that produces a negative output voltage.
This extremely high gain, though, is of little use to us because it makes the amplifier unstable and difficult to control because even the smallest input signals—a few microvolts (V)—would be enough to cause the output voltage to saturate and swing toward one of the voltage supply rails, causing the output to become completely uncontrollable.
An appropriate resistor connected across the amplifier from the output terminal back to the inverting input terminal can be used to reduce and regulate the overall gain of the amplifier because the open loop DC gain of an operational amplifier is extremely high. The result is what is commonly known as negative feedback.

Also state the values of the internal shear force and bending moment at x = 1.4 m and x = 4.9 m. (Answer: At x = 1.4 m, V = 8.51 kN and M = -23.5 kN m and at x = 4.9 m, V = 2.93 kN and M = -2.77 kN m] Note: The best way to handle this is the integration method. Remember there is a reaction moment at the wall at A. That moment acts like an applied moment and that means there is an initial bending moment which is opposite in sign than the applied moment. In other words, the bending moment shifts immediately upward from 0 at x = 0 if the reaction moment at the wall is CW and downward if is CCW. w 1 w = k1x – k2x2 1.8 kN/m 1 4.1 m -2.9 m

The diagram of bending and shearing forces shows the moments and shearing forces acting on any part of the beam. The layout of reinforcement is dependent on the size and sign (or direction) of diagrams in order to withstand these active forces. For instance, shear reinforcement or stirrups are tightly spaced on the region of the beam where shear force is greater.

How to calculate volume of water ?Each millilitre of water has a capacity of one cubic centimetre (1cm3). Some atoms have different sizes and masses. The order in which specific atoms appear on the periodic table depends on how many protons are present in an atom's nucleus. Even though an atom is smaller than another atom, it may nonetheless have more mass. How much water is within a container depends on its shape and how much of it is there. To determine the volume of a square or rectangular vessel, you need to know its length, width, and depth.A cross sectional area of 2800 sq m rose 6 m,
Thus 2800 x 6 = 16800 cubic m of seawater was un displaced
Surface density varies by location and temperature.
A standard figure is 1023.6 kg / cubic m. or 102.36 times denser than pure fresh water.
Therefore the 16800 cubic m of sea water displaced weighed more than the same volume of fresh water.

Over-expanded cycles are engine cycles when the effective compression ratio is less than the effective expansion ratio (see the explanation of the effective compression ratio under Engine Fundamentals). In current practice, either early (EIVC) or late (LIVC) intake valve shutting is used to perform over-expanded cycles.
Temperature lowering at the end of the compression stroke is the main result of EIVC and LIVC. A longer expansion ratio and increased efficiency are produced by using greater geometric compression ratios, which are made possible by the lower temperature.
In honor of their respective inventors, Ralph Miller and James Atkinson, over-expanded cycles are also sometimes referred to as Miller or Atkinson cycles. These words are not consistently used in the literature.

What is a toolpath?The single most crucial element in CNC milling is called a toolpath, which is the data that the milling machine uses to direct the drill bit through the material.
The way that toolpaths function is like a vector; they have a direction, a size, and a position in space. The direction and location of the milling bit in space are directly reflected by these. Toolpaths come in two flavors: 2D and 3D.
An equivalent of a cookie cutter operation, 2D toolpaths for cutting from 2D "sheet" material only operate in the X and Y directions.
In comparison to 3D objects, 2D cuts can be machined much more quickly.
Because the machine only works from the top down, it is very limited in the variety of 3D forms it can fabricate. 3D toolpaths work in the X, Y, and Z directions and are for sculpting and excavating a material, which is a laborious process because each layer must be removed.

This problem provides practice using a while True loop.Write a function named twoWords that gets and returns two words from a user. The first word is of a specified length, and the second word begins with a specified letter. The function twoWords takes two parameters:i. an integer, length, that is the length of the first word andii. a character, firstLetter, that is the first letter of the second word. The second word may begin with either an upper or lower case instance of firstLetter. The function twoWords should return the two words in a list. Use a while True loop and a break statement in the implementation of twoWords.The following is an example of the execution of twoWords:print(twoWords(4, 'B')) A 4-letter word please :twoA 4-letter word please: oneA 4-letter word please : fourA word beginning with B please : appleA word beginning with B please: pearA word beginning with B please: banana['four', 'banana']
The first letter of the second word may appear in either capital or lowercase. The two words in a list should be returned by the function twoWords.
The goal is to create a value-returning function that takes a morse code argument and returns its English translation. We mapped the morse code into the english alphabet, and I created a dict that contains every letter of the morse alphabet. We're going to use morse letters, thus I'm calling this the encoding dict.
Each morse letter corresponds to an english letter to form a function. We're going to name our function translate, and we're going to pass it the input string. I'll give it a longer name. Again, feel free to issue this dictation. It is contained within this function. I'm going to break up Morris' incoming message into its words because we know there are three blanks.

Draw parallels between cyber operations components in defense sector and another section (e.g. finance, health, etc.). Argue why cyber operations should not be allowed in non-military sectors
We show that despite the fact that cyber operations haven't yet been very effective in producing clear results or escalatory, recent policy adjustments and strategy announcements have been.
These modifications are based on the hazardous misconception that attacking is a quick and efficient approach to stop other countries from hacking the United States. New regulations for approving offensive preemptive cyber tactics run the risk of going over the line and altering the rules of the game. Political conflict and coercive diplomacy have historically taken place in cyberspace. A cyber policy with an offensive posture is risky, ineffective, and undermines online norms. Cyber strategy and policy must begin with a thorough understanding of the field, not with hypothetical scenarios.

if the system is released, use conservation of energy to determine the speed of mb just before it strikes the ground. assume the pulley bearing is frictionless
The calculated speed is 3.8 m/s. The system's gravitational potential energy and kinetic energy combined will always remain constant.
So: E=50.0 kg*2.5 m*9.8 m/s2
= 1225 kg*m2/s2
= 1225 J
Since m1 will be lifted when m2 falls, m1 will experience some gravitational potential energy.
E=27.0 kg*2.5m*9.8 m/s2
= 661.5 kg*m2/s2
= 661.5 J E
= 1225 J - 661.5 J
= 563.5 J
Therefore, the system will have 563.5 Joules of kinetic energy when m2 hits the ground. sqrt(E/39.7 kg)
= v sqrt(563.5 J/39.7 kg)
= v sqrt(14.19395466 m2/s2)
= v 3.767486518 m/s
= v E
= 39.7 kg v2 E/39.7 kg
= v2
Since that is the lowest precision datum available, round to 2 significant figures to arrive at a speed of 3.8 m/s.

The most common units for measuring clock speed are MHz (megahertz, or millions of pulses per second) or GHz (gigahertz, or billions of pulses per second)
Explain about the clock rate of the computer?Your CPU's clock speed, which is expressed in GHz, counts the cycles it completes per second (gigahertz). Technically speaking, a "cycle" is a pulse timed by an internal oscillator, but for our purposes, they serve as a fundamental concept that clarifies the pace of a CPU.
Generally speaking, a gaming processor should have a clock speed between 3.5 GHz and 4.0 GHz, but high single-thread performance is more crucial. In other words, your CPU is capable of comprehending and finishing a single task.
A processor's clock speed is how quickly it completes all of its processing cycles in a second. It also goes by the name of clock rate.
