The answer is 75 because 50+60+115=225 divided by 3 is 75
Answer:
π/3
Step-by-step explanation:
We have to find the principal value of
arc sin means sin inverse. The sin inverse is a one to one function with its range between
The principal value of the arc sin will lie within the above given range.
value of sin (60) or sin() is .
lies between
So, from here we can say that the Principal Value of Arc sin(square root of 3/2) is π/3
It should be a right angle (90º).
Answer:
100 psia
Step-by-step explanation:
Applying,
Pressure law,
P/T = P'/T'................. Equation 1
Where P = initial pressure, P' = Final pressure, T = initial temperature, P' = Final temperature.
make P' the subject of the equation
P' = PT'/T............ Equation 2
From the question,
Given: P = 50 psia, T = 300°R = (300×5/9)K = 166.66 K, T' = 600°R = (600×5/9)K = 333.33 K
Substitute these values into equation 2
P' = (50×333.33)/166.66
P' ≈ 100 psia
P ≈ 100 psia
