Answer:
std::string x[n];
int mode1count = 0; // msft
int mode2count = 0; // appl
int mode3count = 0; // csco
int mode4count = 0; // imb
int i;
for(i = 0; i < n; ++i) // Set the array of strings
x[i] = modeList[i];
for(i = 0; i < n; ++i)
{
if(x[i] == "msft")
++mode1count;
else if(x[i] == "appl")
++mode2count;
else if(x[i] == "csco")
++mode3count;
else if(x[i] == "imb")
++mode4count;
}
Explanation:
It is important to ensure that there is adequate space and necessary punctuation when developing codes and programming to avoid getting error messages when running the codes. In this problem, the codes required are shown in the answer section. The codes are properly writing and arranged.
The answer would be -62 because 62 x 1 equals 62 so that would be the answer.
Answer:
Z= 0.868
Explanation:
Given that
P= 3 MPa
T = 160 K
We know that
P v= Z R T
P= Pressure
v = specific volume
R= gas constant
T = Absolute temperature
Z= Compressibility factor
Here specific volume of gas is not given so we assume that specific volume gas

We know that for oxygen gas constant
R = 0.259 KJ/kg.K
Now by putting the values
P v = Z R T
3000 x 0.012 = Z x 0.259 x 160
Z= 0.868
So Compressibility factor is 0.868.
Answer:
= 28800 Pa or 28.8 kPa
Explanation: To determine the pressure of a liquid in a rotating tank,it is used:
p =
- γfluid . z + c
where:
is the liquid's density
w is the angular velocity
r is the radius
γfluid.z is the pressure variation due to centrifugal force.
For this question, the difference between a point on the circumference and a point on the axis will be:
=
- γfluid.
- (
- γfluid.
)
=
- γfluid(
-
)
Since there is no variation in the z-axis, z = 0 and that the density of oil is 0.9.10³kg/m³:
= 

= 28800
The difference in pressure between two points, one on the circumference and the other on the axis is
= 28800 Pa or 28.8 kPa
Because of the skin depth effect, the current at high frequency tends to flow at very low depth from radius. Then at high frequency the effective cross section of the wire is narrower than at DC.
Fro example skin depth at 100 kHz is 0.206 mm (0.008”), a wire more thicker than AWG26 could be a waste of copper, better use a bunch of thin wire (Litz wire) to rise the Q factor.
