Answer:
//Function is written using C++ Programming Language
// Comments are used for explanatory purpose
// The main method is not included
using namespace std;
// Declare arraySum with two arguments. The first represents the array name while the other
// Represents the number of elements
int arraySum(int arr[], int n)
{
int total = 0; // declare and Initialise total to 0
// Iterate through the array to calculate sum
for (int i = 0; i < n; i++) {
total += arr[i];
}
return total;
}
Answer:

Explanation:
Given that

We know that
Rex=ρvx/μ
So


All other quantities are constant only x is a variable in the above equation .so lets take all other quantities as a constant C

We also know that
Nux=hx/K

m is the constant

This is local heat transfer coefficient
The average value of h given as


---------1
The value of local heat transfer coefficient at x=L

-----------2
From 1 and 2 we can say that

Answer:
Elevated stands place the hunter above ground level. They can be tree stands placed in or against trees, or freestanding structures. They have become increasingly popular in recent years with both firearm and bow hunters.
Explanation:
Answer:
(a) attached below
(b)

(c) 
(d)
Ω
(e)
and 
Explanation:
Given data:





(a) Draw the power triangle for each load and for the combined load.
°
°
≅ 

≅ 
The negative sign means that the load 2 is providing reactive power rather than consuming
Then the combined load will be


(b) Determine the power factor of the combined load and state whether lagging or leading.

or in the polar form
°

The relationship between Apparent power S and Current I is

Since there is conjugate of current I therefore, the angle will become negative and hence power factor will be lagging.
(c) Determine the magnitude of the line current from the source.
Current of the combined load can be found by


(d) Δ-connected capacitors are now installed in parallel with the combined load. What value of capacitive reactance is needed in each leg of the A to make the source power factor unity?Give your answer in Ω


Ω
(e) Compute the magnitude of the current in each capacitor and the line current from the source.
Current flowing in the capacitor is

Line current flowing from the source is
