the evaluation in SI unit will be 
Explanation:
We have evaluate 
We know that 1 mm 
So 240 mm 
Newton can be written as 
So 
So the evaluation in SI unit will be
Answer:
For a Singular matrix, the determinant must be equivalent to 0.
Explanation:
A matrix is a rectangular array in which elements are arranged in rows and columns.
Each square matrix has a determinant. The determinant is a numerical idea that has a fundamental function in finding the arrangement just as investigation of direct conditions. For a Singular matrix, the determinant must be equivalent to 0.
Answer:so you can start by thinking about it and creating ideas that work well with it
Explanation:
Try u can do it
Answer:
A. Yes
B. Yes
Explanation:
We want to evaluate the validity of the given assertions.
1. The first statement is true
The sine rule stipulates that the ratio of a side and the sine of the angle facing the side is a constant for all sides of the triangle.
Hence, to use it, it’s either we have two sides and an angle and we are tasked with calculating the value of the non given side
Or
We have two angles and a side and we want to calculate the value of the side provided we have the angle facing this side in question.
For notation purposes;
We can express the it for a triangle having three sides a, b, c and angles A,B, C with each lower case letter being the side that faces its corresponding big letter angles
a/Sin A = b/Sin B = c/Sin C
2. The cosine rule looks like the Pythagoras’s theorem in notation but has a subtraction extension that multiplies two times the product of the other two sides and the cosine of the angle facing the side we want to calculate
So let’s say we want to calculate the side a in a triangle of sides a, b , c and we have the angle facing the side A
That would be;
a^2 = b^2 + c^2 -2bcCosA
So yes, the cosine rule can be used for the scenario above
Answer:
(a). max possible efficiency = 55.62%
(b). max power output = = 133.5 MW
Explanation:
From the question we were given the Maximum temperature in the system as
Tmax = 500°C
Minimum temperature in the system Tmin = 70°C
the Heat supplied to the boiler Qb = 240000 KJ/s
we use the temperature conversion factor from °C to K
given T(K) = T (°C) + 273
⇒ Tmax = 500 + 273 = 773 K
⇒ Tmin = 70 + 273 = 343 K
(a). we are to determine the maximum possible thermal efficiency;
(Πth)max = 1 - Tmin/Tmax
(Πth)max = 1 - 343/773 = 0.5562
(Πth)max = 55.62%
(b). to determine the maximum possible power output for the plant we have;
(Πth)max = Wmax/Qb
where Wmax rep the maximum power output
(Πth)max = 0.5562
Qb = 240000
∴ Wmax = 0.5562 × 240000 = 133505.6 Kw
Wmax = 133.5 MW
cheers i hope this helps
