Answer:
-50.22kJ
Explanation:
Given:
Initial state Temperature =300k
Pressure 1= 150kPa
Pressure 2 = 800kPa
Volume 1 = 0.2m^3
Work done = Pressure 1 × Volume 1 × (inverse of pressure 1 ÷ pressure 2)
= 150kPa × 0.2m^3 × (inv 150 kPa ÷800 kPa)
= - 50.22kJ
Idk what that means i’m sorry
Explanation:
Hello,
Here i am using vectors
\vec{AB}=\vec{DC}=3\vec{i}+3\vec{j}AB=DC=3i+3j
==> AB//DC and AD//BC (definition of a translation)
The quadrilater ABCD is a parallelogram:
so
1) his diagonals have the same length;
2) his diagonals are cutting in the middle.
(these are proprieties of a parallelogram)
Answer:
a. 60V
b. 77.46V
c. 600 W
d. there would be no effect when this is done
Explanation:
a.
to get value of average output
Vo = VsD
Vs = 100V
D = 0.6
Vo = 100 V * 0.6
Vo = 60V
Therefore 60V is the value of average voltage
b.
The rms voltage:
= Vs√D
= 100 x √0.6
= 100 x 0.7746
= 77.46V
the rms voltage is Therefore 77.46V
c.
value of average power:
= (RMS)²/R
R = 10
when we put into formula above,
= (77.46)²/10
= 6000.05/10
= 600.005 W
= 600W
d.
If switching frequency is changes to be 2khz it would actually have no effect on the average voltage, average power or rms voltage.
