please answer i dont understand and dont know the answer​

Answer:

The engine consists of a fixed cylinder and a moving piston. The expanding combustion gases push the piston, which in turn rotates the crankshaft. ... After the piston compresses the fuel-air mixture, the spark ignites it, causing combustion. The expansion of the combustion gases pushes the piston during the power stroke.

Answer:

an internal combustion engine works by combination air fuel and spark all at the right time as well as compression to cause an explosion and push the piston back down and spin the crank shaft wich goes to output

Answer:

The correct answer is "299.88 mm".

Explanation:

The given values are:

Length,

[tex]l_o=300 \ mm[/tex]

Load,

[tex]P=50 \ kN[/tex]

i.e.,

   [tex]=50\times 10^3 \ N[/tex]

[tex]E=200 \ GN/m^2[/tex]

   [tex]=2\times 10^5 \ M/mm^2[/tex]

Now,

Stress,

⇒  [tex]\sigma=\frac{P}{A}[/tex]

On substituting the values, we get

⇒     [tex]=\frac{50\times 10^3}{25\times 25}[/tex]

⇒     [tex]=80 \ N/mm^2[/tex]

The change in length will be:

⇒  [tex]\Delta l=\frac{Pl}{AE}[/tex]

On substituting the values, we get

⇒       [tex]=\frac{50\times 10^3\times 300}{25\times 25\times 2\times 10^5}[/tex]

⇒       [tex]=\frac{15000\times 10^3}{1250\times 10^5}[/tex]

⇒       [tex]=0.12 \ mm[/tex]

hence,

⇒  [tex]L=l_o-\Delta l[/tex]

        [tex]=300-0.12[/tex]

        [tex]=299.88 \ mm[/tex]

Answer: Active solar heating

Explanation:

Active solar heating is a design which is used for the purpose of storage of solar heat for household purposes. The solar heat is used for heat up the liquid and the energy is transferred to the interior space of the house for later use. It distributes the heat throughout the building. Passive solar heating used for heating and cooling of the building but not reliable for storage purposes. Photoelectric heating convert the incident solar heat into electrical energy. Cell heating is a technology in which the thermal energy in a cell is converted into mechanical energy and it is used in machines.

Answer:

your answerbis both technician a and b

Both Technicians A and B because manifold absolute pressure (MAP) sensor can determine the load on the engine.

The manifold absolute pressure sensor (MAP sensor) serves as one that works with intake air pressure which helps to set out the air and fuel quantities required for the ignition cylinders.

Therefore, the MAP sensor voltage will be higher at high altitudes and determine the load on the engine.

Answer:

Iron is manufactured in a blast furnace. First, iron ore is mixed with coke and heated to form an iron-rich clinker called 'sinter'. Sintering is an important part of the overall process as it reduces waste and provides an efficient raw material for iron making. Coke is produced from carefully selected grades of coal.

Copper is typically extracted from oxide and sulfide ores that contain between 0.5 and 2.0% copper. ... Regardless of the ore type, mined copper ore must first be concentrated to remove gangue or unwanted materials embedded in the ore. The first step in this process is crushing and powdering ore in a ball or rod mill.

Explanationl

Given :

Force, [tex]\vec{F}= (2\hat{i} + 5\hat{j})\ kN[/tex].

Force is acting at point A( 2 m, 3 m ) and B( 3 m, 5 m )

To Find :

The work done by force F .

Solution :

Displacement vector between point A and B is :

[tex]\vec{d} = (3-2)\hat{i} + (5-3)\hat{j}\\\\\vec{d} = \hat{i} + 2\hat{j}[/tex]

Now, we know work done is given by :

[tex]W = \vec{F}.\vec{d}\\\\W= (2\hat{i} + 5\hat{j}).(\hat{i}+\hat{2j})\\\\W = (2\times 1) +( 5\times 2) \ kJ\\\\W = 12 \ kJ[/tex]

W = 12000 J

Therefore, work done by force is 12000 J .

The advantage to using a rosebud tip is that it expands the flame temperature over a wider area vs using a #0 size tip.

Explanation:

Hope this helped Mark BRAINLIEST!!

The advantage to using a rosebud tip is that it expands the flame temperature over a wider area vs using a #0 size tip.

The degree to which an object is hot or cold is measured by its temperature.

Temperature is what we refer to when we talk about how something feels warm. We can determine how much heat or energy an object contains by measuring its temperature, which is typically expressed in degrees Fahrenheit or degrees Celsius.

The heat we feel on our hands and faces is produced by highly active molecules in a boiling cup of water that are moving very quickly throughout the liquid. The energy content of colder objects is lower. These molecules have far less activity.

Therefore, The advantage to using a rosebud tip is that it expands the flame temperature over a wider area vs using a #0 size tip.
