The value is 
Explanation:
From the question we are told that
The saturation density of air is 
The temperature for this saturation density to occur 
The relative humidity at this temperature is 
Generally the relative humidity is mathematically represented as

Here H represents humidity
=> 
=> 
=> 
Answer:
75
Explanation:
i am not sure but if 200N boy is being held back then the force that's holding him back must be equal to or greater than his weight. if 125N is already exerted then the tension will be:

Answer:
the velocity of the water flow is 7.92 m/s
Explanation:
The computation of the velocity of the water flow is as follows
Here we use the Bernouli equation
As we know that

= 7.92 m/s
Hence, the velocity of the water flow is 7.92 m/s
We simply applied the above formula so that the correct value could come
And, the same is to be considered
