Which of the following describes braking from a brake chamber containing a power spring?

A spring released and air-applied parking brake

A spring applied and air-released parking brake

A spring released and air-applied service brake

A spring applied and air-released service brake

Answers

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.

A spring applied and air-released service brake is the one that describes braking from a brake chamber containing a power spring.

Thus, the correct option is D.

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

Answers

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

a=4r/√3

=(2×55.85 g.[tex]mol^{-1}[/tex])/(4×0.124×[tex]10^{-7}[/tex]/√3)×6.022×[tex]10^{23}[/tex]

ρ=7.8 g/cm³.

Hence, we get the density as 7.8g/cm³.

Hello,
Can someone solve this short exercise please. Only the calculation parts (a and c)

Answers

a) From the the given data:

The 2020 GDP / capita for Ni is 1.94

The 2020 GDP / capita for United States is 63.23

The equivalent CO2 emissions per equivalent US$ of GDP for Ni/geria

is 1.265

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 capita

GDP 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 GDP

Equivalent 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/geria

Given 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

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?

Answers

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.

(5 points) Knowing that the ammeter must be connected in series with the circuit and the voltmeter must be connected in parallel, what does this tells you about the internal resistance of each device?

Answers

Answer:

This tells us that the internal resistance of the ammeter is very low because we would not want to impede the flow of current when trying to measure current. The internal resistance of the voltmeter must be high because it is added in parallel with the circuit and if added in series, it would cause resistance and alter the voltage reading.

If you want to revise a sketch or a feature when using a 3D CAD program, how do you make a correction without using the undo function

Answers

Answer:

See explanation

Explanation:

Truthfully, this answer can vary depending on the CAD program you are choosing to use. Generally, you go to your model tree (this has been on the left hand side of the screen in all of the CAD software I have used) and click the sketch or feature to edit. In some programs this is a left click and in others this is a right click. When the feature is correctly selected a menu should appear with the option to edit feature/sketch/definition/etc. Select this option and you should be able to edit what you wanted to.
