The 2013 Rolls Royce Ghost Alpine has a top speed of 155 miles per hour. Calculate the speed in centimeters per second.

Answers

AutoChina Shanghai 2013 also plays host to the world debut of the latest Bespoke Collection from the world’s pinnacle super-luxury marque.

The Alpine Trial Centenary Collection celebrates an extraordinary moment in Rolls-Royce and automotive history. A century ago this June, four Rolls-Royce Silver Ghosts embarked on the Austrian Alpine Trials, the most arduous test of automotive endurance of the time.

In performing without fault over 1820 gruelling miles of near impassable mountain terrain, the Rolls-Royce works team and privateer entrant James Radley helped cement the marque’s reputation for peerless reliability and mechanical excellence, a reputation the company proudly retains today. In doing so establishing the legend of Rolls-Royce as maker of the ‘Best Car in the World’.

This limited edition of Rolls-Royce Ghosts feature exquisitely crafted design cues that pay tribute to these extraordinary motor cars. The exterior paint hue, for example takes close inspiration from Radley’s Silver Ghost, a car that stands side-by-side with the 2013 model in Shanghai.

what are three limitations of current cloaking technology.
Get this correct I'll give you 40 points.​

Answers

Explanation:

1.undetectable to electromagnetic waves

2.hiding an object from an illumination containing diffre t wave lengths become difficult as the object sizes grow.

3. reduce the scattering by two orders.

Electromagnetic waves are unable to detect it. With increasing item sizes, it becomes more challenging to conceal an object from an illumination with various wave lengths. two orders down on the scattering.

What is current cloaking technology?

Current clocking technology is defined as a hypothetical or made-up stealth technology that makes things like people or spaceships completely or partially invisible to certain electromagnetic (EM) spectrum wavelengths. In a specific frequency band, this gadget renders an object "invisible" to electromagnetic radiation. Obviously, cloaks that operate in the visible spectrum have the most fascinating potential uses.

These metamaterials, according to the researchers, can shield a medium-sized antenna from radio waves over a wide range of bandwidths, resulting in clearer communications. However, as visible light wavelengths are far shorter than radio waves, it is practically difficult to conceal huge things from them, such as the human body. The issue with present designs is that they can only handle a certain amount of bandwidth. Even this "perfect" 3D cloak that was previously exhibited could only conceal items from microwaves.

Thus, electromagnetic waves are unable to detect it. With increasing item sizes, it becomes more challenging to conceal an object from an illumination with various wave lengths. two orders down on the scattering.

Hello!

In this case, according to the stoichiometry of the reaction, it is possible to evidence the 1:1 mole ratio between lead (II) ions and lead (II) sulfate precipitate; that is why we can compute the mass of lead (II) in the polluted water as shown below:

How to make 0.01 Molar solution in 30 ml of water

Answers

Answer:

You see the concentration decreased ten fold, from 1 M to 0.1 M.

You can simply increase the volume by ten times.

For example

If you have 250 mL of 1 molar HCl, you can add distilled water upto 2500 mL. Now the concentration is 0.1 molar.

If you want to use the serial dilution method, you can use the C1V1=C2V2 equation.

C1 = starting concentration.

C2 = final concentration.

V is for volume.

So let's say you have 500 mL of 1 M HCl and you only want 50 mL of 0.1 M HCl.

1 M x V1 = 0.1 M x 50 mL

V1 = 5 mL

So you take 5 mL of the original (stock) solution and dilute it up to 50 mL. Then you have 50 mL of 0.1 M HCl.

A sample containing solid sodium benzoate mixed with sodium chloride is dissolved in 50.0 mL of .5 M HCl, giving an acidic solution (benzoic acid mixed with HCl ). This mixture is then titrated with .393 M NaOH. After the addition of 46.50 mL of the solution, the pH is found to be 8.2. At this point, the addition of one more drop ( .02 mL) of NaOH raises the pH to 9.3 . Calculate the mass of sodium benzoate (NaC6H5COO) in the original sample.

Why do particles with different masses have the same kinetic energy when at the same temperature?

Answers

Answer: Because Kinetic energy depends on temperature and not mass

Explanation:

Average kinetic energy is defined as the average of the kinetic energies of all the particles present in a system. It is determined by the equation:

[tex]K.E=\frac{3RT}{2}[/tex]

where K.E = Kinetic energy

R= gas constant

T= temperature in kelvin

It is visible that kinetic energy is dependent on the temperature of the system and not on the mass of the system. Thus particles with different masses have the same kinetic energy when at the same temperature

The pressure 15.0 m under water is 248 kPa.
What is this pressure in torr

Answers

Answer:

1860 torr

Explanation:

In order to convert from kPa to torr, we are going to use the following conversion factor:

1 kPa = 7.5 torr

Now we multiply 248 kPa with this factor so that the kPa units cancel each other and only the torr units remain:

248 kPa * [tex]\frac{7.5torr}{1kPa}[/tex] = 1860 torr

This means that the answer is 1860 torr.

He then observes the temperature of the water fall from 20.0°C to 15.0°C over the course of 4.3 minutes. Use this data, and any information you need from the ALEKS Data resource, to answer the questions below about this reaction:

NH4NO3(s) → NH4+(aq) + NO3^- (aq)

Required:
a. Is this reaction exothermic, endothermic, or neither?
b. If you said the reaction was exothermic or endothermic, calculate the amount of heat that was released or absorbed by the reaction in this case.

Answers

Answer:

a. Endothermic

b. 6586J are absorbed.

Explanation:

a. When the reaction occurs, the temperature is decreasing from 20.0°C to 15.0°C, that means the reaction is absorbing heat and is endothermic.

b. To find the heat absorbed we must use:

Q = -m*ΔT*C

Where Q is change in heat,

m is the mass of solution (300g + 14.8g = 314.8g)

ΔT is change in temperature (15.0°C - 20.0° = -5.0°C)

And C is specific heat of the solution (4.184J/g°C assuming is the same heat than the heat of pure water).

Replacing:

Q = -314.8g*-5.0°C*4.184J/g°C

Q =

6586J are absorbed
