Answer:

Explanation:

A. Polarization is simple for most antennas to determine. It is only on the same level as the antenna components. A vertically polarised antenna (that is one with vertical elements) is better received and a horizontal antenna is equally provided with horizontally polarised signals.

B. The left-hand circular polarization is named if the electric chambers vector rotates counter-clockwise as far as they are from the antenna.

The right-hand circular polarisation is named as the electric field vector rotates counter-clockwise as far as it gets from the antenna.

It then goes without stating the polarisation on the right hand is orthogonal to the left.

C. signals of the same frequency can be transmitted together in an non-interfering manner as long as their polarizations are orthogonal to one another. This too a correct statement.

Answer:

#here is code in python.

#read number of shares

num_share = int(input("Enter number of shares:"))

#read purchase price

buy_p = float(input("Enter purchase price:"))

#read sell price

sell_p = float(input("Enter sale price:"))

#total buying cost

buy_cost=buy_p*1.03*num_share

#total selling cost

sell_cost=sell_p*0.97*num_share

#if net profit

if(sell_cost>buy_cost):

print("After the transaction, you made " +str(sell_cost-buy_cost)+ " dollars.")

#if net loss

else:

print("After the transaction, you lost " +str(buy_cost-sell_cost)+ " dollars.")

Explanation:

Read the total number of shares from user.Then read buying price of a share and selling price of a share.Then calculate total buying cost including commission.Calculate total selling cost excluding the commission.If total buying cost is greater than total selling cost the print the profit else print the loss in the transaction.

Output:

Enter number of shares:10

Enter purchase price:10

Enter sale price:10

After the transaction, you lost 6.0 dollars.

<h3>What is a SELECT query?</h3>

A select query is known to be a kind of a database object that depicts the information that is shown in Datasheet view.

Note that A query does not save data, it shows data that is saved in tables. The SELECT statement is known to be one that is often used to select data from what we call a database.

Hence, The data returned is said to be saved in a result table, known to be the result-set.

Based on the above, the SQL SELECT built-in function COUNT none of the above options.
