Answer:
(a)False (b)False (c)False (d)False (e)False
Explanation:
a) Continuous time signal can also be digital. e.g continuous time square waveform (see first picture)
b) A discrete time signal can also be analog. e.g discrete time exponential function can take any value (see second picture)
c) When both energy and power of signal are infinite, it is neither power signal nor energy signal e.g ramp signals, 
signal
d)A signal of infinite length can also have finite energy. e. g
e)Step waveform u(t) is a power signal but also causal
The answer here is letter C. The optimal solution. The optimal solution is the one that affects how certain things changes with sensitivity analysis. The optimal solution is a feasibility solution where the objective function of it is to reach the minimum and maximum value.
Answer: The number of moles of 
produced are, 0.287 moles.
Explanation : Given,
Mass of 
= 14.9 g
Molar mass of = 32 g/mol
First we have to calculate the moles of
Now we have to calculate the moles of
The balanced chemical equation is:
From the reaction, we conclude that
As, 13 mole of react to give 8 moles of
So, 0.466 mole of react to give 
mole of
Therefore, the number of moles of produced are, 0.287 moles.
Answer:
27.99 dm³
Explanation:
Applying
PV = nRT................ Equation 1
Where P = Pressure, V = Volume, n = number of mole, R = molar gas constant, T = Temperature.
From the question, we were aksed to find V.
Therefore we make V the subject of the equation
V = nRT/P................ Equation 2
Given: n = 1.31 moles, T = 37°C = 310K, P = 904 mmHg = (904×0.001316) = 1.1897 atm
Constant: R = 0.082 atm.dm³/K.mol
Substitute these values into equation 2
V = (1.31×310×0.082)/(1.1897)
V = 27.99 dm³
