At the initial state: v1 = vf = 0.001053 m

/kg, h1 = hf = 467.11 kJ/kg, and s1 = sf = 1.4336 kJ/kgK.
The mass of the water is: m = V/v1 = 0.005/0.001053 = 4.7483 kg.
To find the final state, we will use the First Law:
Q12 = m(h2 - h1) for closed system undergoing a constant pressure process.
h2 = 1Q2/m + h1 = 2200/4.7483 + 467.11 = 930.43 kJ/kg.
At P2 = P1 = 150 kPa, this is a saturated mixture.
hf = 467.11 kJ/kg, hfg = 2226.5 kJ/kg, sf = 1.4336 kJ/kgK, and sfg = 5.7897 kJ/kgK
s2 = sf + sfg (h2 – hf )/hfg = 1.4336 + 5.7897(930.43 – 467.11)/2226.5 = 2.6384 kJ/kgK.
The entropy change of water is:
Delta Ssys= m(s2 – s1) = 4.7483(2.6384 – 1.4336) = 5.72 kJ/K.
Hey there!
They answer is option C music would make it harder to focus on the road.
Hope this helps.
Probably the earth traveling around the sun
Answer:it has risen
Explanation:
It has risen due to the burning of fossil fuels which produces a lot of green house gases.and it has also risen due to deforestation,no enough plants to consume the green house gas(carbon dioxide)
Answer:
The percentage of legal quarters that will be rejected is 1.954 %.
Explanation:
Here we are required to find
P(X<5.48 or X>5.82)
We have μ = 5.67 and σ = 0.07 where the range is between 5.48 and 5.82 we each z-score given by
Therefore for 5.48 we have 
= -2.714
and for 5.82 we have 
= 2.143
Therefore we have the area of interest on the normal distribution chart given by
P(Z<-2.714) + P(Z > 2.143) = P(Z<-2.714) + (1 - P(Z < 2.143))
+ 0.00336 + 1 - 0.98382 = 0.01954
= 0.01954 × 100 = 1.954 %
Therefore 1.954 percentage of legal quarters will be rejected.
