technician a says that gasoline engines have spark plugs to ignite the air-fuel mixture.technician b says that diesel engines use compression to ignite the air-fuel mixture. who iscorrect?
It is right to state that Technician B is correct. A piston compresses the air in the cylinder, causing it to become very hot. The diesel is then atomized in the injectors and sprayed into the heated air as a mist. The heated air ignites the gasoline quickly, creating ignition.
What is compression in Engines?As the fuel injectors drive air and fuel into the combustion chamber, compression occurs in the internal combustion cylinders.
The mixture ignites, and the piston is driven by the expansion of the burning gases in the cylinders, converting the energy from combustion into mechanical energy that propels the vehicle.

Explanation:
(5 points) Some strands of Christmas tree lights are sometimes wired in series. What happens to the other lights if one of the series bulbs is removed? Other lights are sometimes wired in parallel. What happens when one of these parallel bulbs is removed? Explain why
Answer:
Series: All the lights go out
Parallel: Nothing happens
Explanation:
Often referred to as ‘daisy-chained’ or ‘looped’ the current in a series circuit follows one path from start-to-finish with the Anode (positive) of the second LED connected to the Cathode (negative) of the first. The image to the right shows an example: To wire a series circuit like the one shown, the positive output from the driver connects to the positive of the first LED and from that LED a connection is made from the negative to the positive of the second LED and so on, until the last LED in the circuit. Finally, the last LED connection goes from the negative of the LED to the negative output of the constant current driver, creating a continuous loop or daisy chain. When one goes out, the whole strand of light stops working with it.
Parallel circuit (when lights are wired in parallel):
Where a series circuit receives the same current to each LED, a parallel circuit receives the same voltage to each LED and the total current to each LED is the total current output of the driver divided by the number of parallel LEDs.
In a parallel circuit all the positive connections are tied together and back to the positive output of the LED driver and all the negative connections are tied together and back to the negative output of the driver. Lets take a look at this in the image to the right. Using the example shown with a 1000mA output driver, each LED would receive 333mA; the total output of the driver (1000mA) divided by the number of parallel strings (3).
In written specifications, under the heading Painting and Finishing, which of the following would not be appropriate?
A. Surfaces to be included (interior and exterior).
B. Specific cations of materials to be used.
C. Application method and number of coats.
D. Number of painters to be used on the job.
E. Guarantee of quality and performance.
F. Completion date.
Answer:
F. Completion date.
Explanation:
The completion date cannot be determined exactly before the job; it is also irrelevant to Painting and Finishing.

The equivalent CO2 emissions per equivalent US$ of GDP for United States is 0.218
c) From the typical trend predictions, the equivalent CO2 emission per equivalent US$ for the year 2035 is 513.59 T g C / yr
How to find the GDP per capitaGDP per capita is solved by gross domestic product GDP divided by population
GDP per capita for Ni/geria
= 400 / 206
= 1.94
GDP per capita for United States
= 20930 / 331
= 63.23
How to find equivalent CO2 emissions per equivalent US$ of GDPEquivalent CO2 emissions per equivalent US$ of GDP is gotten by
= CO2 emissions / GDP
Ni/geria
= 506 / 400
= 1.265
United States
= 4570 / 20930
= 0.218
How to compute equivalent CO2 emission per equivalent US$ for the year 2035 for Ni/geriaGiven that CO2 increment per year is 0.1% / yr. From 2020 to 2035 is 15 years and this shows increment of 15 * 0.1 = 1.5%
At 2020 it was 506 Tg C / yr with 1.5% increment we have
= 506 * 1.5%
= 7.59
The increment is 506 + 7.59 = 513.59 Tg C / yr
Therefore the equivalent CO2 emission per equivalent US$ for the year 2035 is 513.59 Tg C / yr

thermal-hydraulic study of the lbe-cooled fuel assembly in the myrrha reactor: experiments and simulations
For many cutting-edge systems based on fast neutrons, heavy liquid metals (HLMs), such as lead-bismuth eutectic (LBE) and pure lead, are popular candidate coolants.
LBE is employed, in instance, in Mol (Belgiumgroundbreaking )'s MYRRHA fast reactor, which can run in either critical mode or as a sub-critical accelerator-driven system. Key thermal-hydraulic features of these systems, such as the proper cooling of fuel components, must be evaluated with a heavy emphasis on safety.
This flow scenario presents a challenge for computational fluid dynamics (CFD) models, such as those used to relate the turbulent transport of momentum and heat, due to the complicated geometry and low Prandtl number of the LBE (Pr 0.025). Therefore, accurate experimental information is required for validation.

iron(Fe) has a bcc crystal structure, an atomic radius of 0.124nm, and an atomic weight of 55.85g/mol. what is the theoretical density
Iron has a BCC crystal structure, an atomic radius of 0.124 nm and atomic weight of 55.85g/mol, so the theoretical density will be 7.8 g/cm³.
What is Atomic Radius?In a molecule, an atomic radius is equal to half the distance between neighboring atoms of the same element.
When we travel down a group, the atomic radius increases, and when we move in a period from left to right, it decreases. The valence electrons being in the same outermost shell at various times explains this. Moving from left to right, the atomic number rises during the same time interval, increasing the effective nuclear charge. Elemental atomic radius decreases as attractive forces rise.
The given values in the question are :
Radius=0.124 nm and,
Atomic weight=55.85 g/mol
For BCC, Z=2
r=0.124 nm=0.124×[tex]10^{-9}[/tex] m
=0.124×[tex]10^{-9}[/tex]×10² cm
ρ= (Z×M)/a³ N₀

The one that describes braking from a brake chamber containing a power spring is a spring applied and air-released service brake. The correct option is D.
What is spring brake?Spring brakes, unlike service brakes, are not air applied. They apply when air pressure is released from the brake chamber and release when air pressure is restored. Spring brakes and service brakes use different types of brake chambers.
The braking power of spring brakes is determined by how well the brakes are adjusted. If the brakes are not properly adjusted, neither the regular nor the emergency/parking brakes will function properly.
