When sulphur burns it turns to sulphur dioxide
Answer:
The flow area at the location where the Mach number is 0.9 is 25.24 cm²
Explanation:
Here we have for isentropic flow;
Where:
A = Area of flow = 36 cm²
M = Mach number at section of = 1.8
k = Specific heat ratio = 1.4
A* = Area at the throat
Therefore, plugging the values we get
Therefore, A* = 36/1.439 = 25.01769 cm²
Where the Mach number is 0.9, we have
Therefore A = 25.020× 1.009 = 25.24 cm²
The flow area at the location where the Mach number is 0.9 = 25.24 cm².
Answer:
m = 0.59 kg.
Explanation:
First, we need to find the relation between the frequency and mass on a spring.
The Hooke's law states that
And Newton's Second Law also states that
Combining two equations yields
The term that determines the proportionality between acceleration and position is defined as angular frequency, ω.
And given that ω = 2πf
the relation between frequency and mass becomes
.
Let's apply this to the variables in the question.
I would say, none of them is correct.
Because W= F.d, Here it is read: Work equals Force dot distance. It is a dot product not a cross product.
But for this question, if you have to choose something. Choose W=Fxd.
Hope this helps.
