The relative humidity is 100%.
To find the answer, we have to know about the relative humidity.
<h3>What is the relative humidity?</h3>
- The amount of water vapor in the air is referred to as humidity.
- The gaseous and invisible condition of water is called water vapor.
- Humidity can be expressed in a variety of ways, including absolute humidity, relative humidity, mixing ratio, and dew point temperature.
- Relative humidity can be expressed as,
![Rel.Humidity=\frac{P_{vapor}}{P_{sat}}*100](https://tex.z-dn.net/?f=Rel.Humidity%3D%5Cfrac%7BP_%7Bvapor%7D%7D%7BP_%7Bsat%7D%7D%2A100)
- Here, it is given that, the vapor pressure is the same as the saturation vapor pressure, thus,
![Rel.Humidity=\frac{P_{sat}}{P_{sat}}*100=100](https://tex.z-dn.net/?f=Rel.Humidity%3D%5Cfrac%7BP_%7Bsat%7D%7D%7BP_%7Bsat%7D%7D%2A100%3D100)
Thus, we can conclude that, the relative humidity is 100%.

For the first question, make a question that is quantifiable
or can be counted. This can be anything, as long as its quantifiable, like "How many species of trees are in this certain area?" While for the second it can be a question that can is more
qualitative and are more open-ended questions, example, “What are the
contaminants present in this water sample”
Answer:
Okay I might be wrong and sorry if i am either its 12 or 0.402
Explanation:
* I recommend the second one cause its more logical
Be aware I might be wrong
Refer to the figure shown below.
W = 217/2 = 108.5 N, the weight of one half of the board.
N = W = 108.5 N, the normal reaction at B or C.
R = frictional force at B or C preventing the board from sliding.
The vertical dashed line through A is a line of symmetry.
By definition,
R = μN = 108.5μ N
where
μ = the static coefficient of friction between the board and the ground.
From geometry,
h = 2a tan(30°) = 1.1547a
Take moments about A for the member AB.
2aN - Rh -Wa = 0
2a(108.5) - 108.5μ(1.1547a) - 108.5 a = 0
217 - 125.285μ - 108.5 = 0
125.285μ = 108.5
μ = 0.866
This is the minimum required static coefficient of friction
Answer: 0.866
