The reason why the colorimetric CO₂ detector does not turn yellow is because; The endotracheal tube is not in the trachea and as such the patient is not exhaling CO₂
<h3>Usage of Colorimeter Detector</h3>
The colorimetric CO₂ detector is simply a device that shows the existence of exhaled CO₂
Now, the colorimetric CO₂ detector has a pH-sensitive filter that could change color when it gets into contact with the CO₂ exhaled by the patient.
Thus, when the patient is not exhaling CO₂ , the pH filter will turn to purple and when the patient is exhaling CO₂ , the pH filter turns yellow.
The complete question is;
You are resuscitating a critically ill newborn whose heart rate is 20 bpm. The baby has been intubated and the endotracheal tube insertion depth is correct. You can see chest movement with PPV and hear bilateral breath sounds, but the colorimetric CO₂ detector does not turn yellow. What is the likely reason for this?

The work done by gravity and work done by air resistance are respectively; Negative, Negative.
<h3>Work done by gravity and air resistance</h3>
The work done by both gravity and air resistance are both negative.
The reason is because as the ball is hit in the upward direction, it is moving against the forces of gravity and as such air resistance will be acting in the downward direction on the baseball.
Thus, we can conclude that the work done by the force of gravity and air resistance is in an opposite direction to the movement of the baseball and this implies negative work done.

Answer:
B.
Fashion blog
Explanation:
From the list of options, the only reliable source would be a Fashion Blog. A website by an unknown author is never a reliable source. An article published 20 years ago would not be considered reliable since the information is completely outdated, styles and rules change every couple of years and therefore that information would not apply in today's world. A government agency does not bother with fashion in the workplace. Therefore, a fashion blog would be the only option. A fashion blog deals with all forms of fashion including workplace fashion and best clothes for such occasions.
