Answer:0.853
Explanation:
Given
Reliability of A is 0.90
Reliability of B is 0.80
Reliability of C is 0.99
B has a backup with reliability of 0.8
i.e. B has a component in parallel to it.
A,B& C is series.
B actual reliability is
Thus 
is given by
For many solids dissolved in liquid water, the solubility increases with temperature. The increase in kinetic energy that comes with higher temperatures allows the solvent molecules to more effectively break apart the solute molecules that are held together by intermolecular attractions.
Answer:
Explanation:
60000 kJ / h = 60000 x 1000 / (60 x 60 )
= 16667 J /s
a)
where 
and 
are heat supplied and heat given from outside source .
Here = 16667 J/s
= 15.684
16667 / W = 15.684
W= minimum power supplied = 1062.7 W.
b )
If 
=19.87
= 838.8 W .
Sum of the first ten digits is:
7+3+4+5+4+1+7+8+0 = 39
39, when divided by 9 give you the remainder of 3
9 x4, is 36
36 +3 equals 39
(39 = 9 x 4 + 3)
So X= 0
