Answer:

(a)  0.912 atm = 693.12 torr

(b)  0.685 bar = 68.5 kpa

(c)  655 mm Hg = 0.8618 atm

(d)  1.323x10⁵ Pa = 1.305 atm

(e)  2.50 atm = 36.74 psi

Explanation:

(a) 0.912 atm to torr

We know that 1 atmospheric pressure (Atm) is equal to 760 torr (mm Hg)

so 0.912*760 = 693.12 torr

(b) 0.685 bar to kilopascals

We know that 1 bar is equal to 100 kpa

so  0.685*100 = 68.5 kpa

(c) 655 mm Hg to atmospheres

We know that 1 atmospheric pressure (Atm) is equal to 760 torr (mm Hg)

so 655/760 = 0.8618 atm

(d) 1.323x10⁵ Pa to atmospheres

We know that 1 atm is equal to 101,325 Pascals

so  1.323x10⁵/101,325 = 1.305 atm

(e) 2.50 atm to psi

We know that 1 atm is equal to 14.696 pound-force per square inch (psi)

so 2.50*14.696 = 36.74 psi

Answer:

(a) 693.12 torr

(b) 68.5 kilopascals

(c) 0.862 atmosphere

(d) 1.306 atmospheres

(e) 36.74 psi

Explanation:

(a) 0.912 atm = 0.912 atm × 760 torr/1 atm = 693.12 torr

(b) 0.685 bar = 0.685 bar × 100 kPa/1 bar = 68.5 kPa

(c) 655 mmHg = 655 mmHg × 1 atm/760 mmHg = 0.862 atm

(d) 1.323×10^5 Pa = 1.323×10^5 Pa × 1 atm/1.01325×10^5 Pa = 1.306 atm

(e) 2.50 atm = 2.50 atm × 14.696 psi/1 atm = 36.74 psi

The chemical equation below shows the reaction of methane (CH4) and oxygen gas (O2) to form carbon dioxide (CO2) and water (H2O)
Nuetrik [128]
<h2>Answer </h2>

Option C - Carbon Dioxide and Water

<u>Explanation </u>

The chemical equation reaction of methane (CH4) and oxygen gas (O2) to form carbon dioxide (CO2) and water (H2O).

CH4 + 2O2 → CO2 + 2H2O.

In this equation, carbon dioxide and water are products. Products are substances which are formed after a chemical reaction so in this case carbon dioxide and water are formed as a result after a chemical reaction. Therefore, these are products of reaction of methane and oxygen gas.

A rotating object has an angular acceleration of α = 0 rad/s2. Which one or more of the following three statements is consistent
Murrr4er [49]

Answer:

A,B and C

Explanation:

Statement A  

At all times, angular velocity is \omega = 0\,{\rm{rad/s}  

Angular acceleration is the rate of change in angular velocity with respect to time.  

Angular velocity and angular acceleration are related by  

{\omega _{\rm{f}}} = {\omega _{\rm{i}}} + \alpha t

Which when re-arranged becomes  

\alpha = \frac{{{\omega _{\rm{f}}} - {\omega _{\rm{i}}}}}{t}

There’s no change in angular velocity anytime when the angular velocity is \omega = 0\,{\rm{rad/s}}

The equation can be modified as follows:  

\begin{array}{c}\\\alpha = \frac{{0\,{\rm{rad/s}} - 0\,{\rm{rad/s}}}}{t}\\\\ = 0\\\end{array}

Therefore, the angular acceleration becomes zero hence statement A is valid.  

Statement B  

Angular acceleration is the rate of change in angular velocity with respect to time.  

Angular velocity and angular acceleration are related by  

{\omega _{\rm{f}}} = {\omega _{\rm{i}}} + \alpha t

Which when re-arranged becomes  

\alpha = \frac{{{\omega _{\rm{f}}} - {\omega _{\rm{i}}}}}{t}

There’s no change in angular velocity anytime when the angular velocity is \omega = 10\,{\rm{rad/s}}.The final and initial velocities remain the same.  

The equation can be modified as follows:  

\begin{array}{c}\\\alpha = \frac{{10\,{\rm{rad/s}} - 10\,{\rm{rad/s}}}}{t}\\\\ = 0\\\end{array}

Therefore, the angular acceleration becomes zero and statement B is valid  

Statement C  

Angular velocity is defined as the change in the angular position with respect to time.  

Angular velocity and angular displacement are related by  

\theta = \omega t

Which can also be modified as:  

{\theta _{\rm{f}}} - {\theta _{\rm{i}}}

Note that the final position is {\theta _{\rm{f}}}and initial position is {\theta _{\rm{i}}}

Modifying the equation to find the angular velocity we obtain  

\omega = \frac{{{\theta _{\rm{f}}} - {\theta _{\rm{i}}}}}{t}

When the angular displacement has the same value at all times, the equation becomes  

\begin{array}{c}\\\omega = \frac{{{\theta _{\rm{i}}} - {\theta _{\rm{i}}}}}{t}\\\\ = 0\\\end{array}

The angular velocity becomes zero.  

Angular acceleration and angular velocity are related by  

{\omega _{\rm{f}}} = {\omega _{\rm{i}}} + \alpha t

The expression above can be rearranged as follows:  

\alpha = \frac{{{\omega _{\rm{f}}} - {\omega _{\rm{i}}}}}{t}

At all times, the angular velocity is \omega = 0\,{\rm{rad/s}} hence initial and final velocities remain the same  

We obtain  

\begin{array}{c}\\\alpha = \frac{{0\,{\rm{rad/s}} - 0\,{\rm{rad/s}}}}{t}\\\\ = 0\\\end{array}

Therefore, the angular acceleration becomes zero and statement C is valid.  

Therefore, statements A,B and C are consistent .

In order to change the color of light, you must change___?
Bogdan [553]
In order to change the colour of the light, you would need to change both the wavelength and frequency of light, as light in the visible spectrum, have their own unique wavelengths that they occur in along with the measure of frequency, which measures the number of cycles or turns a wave can occur from trough to trough or crest to crest within a given period of time.
