we have
x<5
x>c
we know that
The solution is the intersection of both solution sets of the given inequalities.
The solutions of the compound inequality must be solutions of both inequalities.
The value of c could be 5 or any number greater than 5, such that there are no solutions to the compound inequality
Because
A number cannot be both less than 5 and greater than 5 at the same time
therefore
the answer is
for c_> there are no solutions to the compound inequality
Answer:
Output voltage equation is
Explanation:
Given:
dc gain dB
Input signal
Now convert gain,
DC gain at frequency is given by,
At zero frequency above equation is written as,
Now we write output voltage as input voltage,
Therefore, output voltage equation is

- The plot of the graph is given in attachment.
- The code covers the entire spectrum of the poly-tropic range ( 1.2 - 1.6 ) and 20 steps ( cases ) have been plotted and compared in the attached plot.
Answer:
Electroosmotic velocity will be equal to
Explanation:
We have given applied voltage v = 100 volt
Length of capillary L = 5 mm = 0.005 m
Zeta potential of the capillary surface
Dielectric constant of glass is between 5 to 10 here we are taking dielectric constant as
Viscosity of glass is
Electroosmotic velocity is given as
So Electroosmotic velocity will be equal to
Given:
Temperature of water, = =273 +(-6) =267 K
Temperature surrounding refrigerator, = =273 + 21 =294 K
Specific heat given for water, = 4.19 KJ/kg/K
Specific heat given for ice, = 2.1 KJ/kg/K
Latent heat of fusion, = 335KJ/kg
Solution:
Coefficient of Performance (COP) for refrigerator is given by:
Max =
= = 9.89
Coefficient of Performance (COP) for heat pump is given by:
Max = = 10.89
