Answer:

char

Explanation:

The character data type written as char holds any single character, numbers and non-printing characters. In java and most programming languages, the value of the character must be placed within single quotes. for example

char c = 'd'

char c = '9'

char c = '\t'

Are all valid declarations of a variable c as char and assigned d, then 9 and then used with a non-printing character (tab ) with the escape sequence.

<h2>Answer:</h2>

char

<h2>Explanation:</h2>

In Java and some other programming languages, the data type used to hold a single character including numbers and non-printing characters is char.

Examples of single characters (numbers) that can be held by a char data type are;

(i) 065 - which represent an ASCII code for character 'A' (without quotes)

(ii) 097 which represent an ASCII code for character 'a' (without quotes)

Examples of single characters (non-printing) that can be held by a char data type are;

(i) Non-breaking space

(ii) Tab character

Examples of other single characters that can be held by a char data type are;

(i) 'd' - character d (without quotes)

(ii) 'M' - character m (without quotes)

trapecia [35]

Answer:

5 Letters

Explanation:

So we need 12 distinct codes made of a single letter or a pair of letters.

What would be the least number of letters?

Lets try with 3 letters A, B and C

The possible combinations are: A, B, C, AB, AC, BC

These are 6 codes and we need 12 so lets try more A, B, C and D

The possible combinations are: A, B, C, D, AB, AC, AD, BC, BD, CD

These are 10 codes and we need 12 so lets try more A, B, C, D and E

The possible combinations are:

A, B, C, D, E, AB, AC, AD, AE, BC, BD, BE, CD, CE, DE

Finally we got 15 distinct codes which are more than 12 so the least number of letters needed are 5.

Using formula:

Four letters = 4C1 + 4C2 = 4 + 6 = 10

Five letters = 5C1 + 5C2 = 5 + 10 = 15

Explain benefits and disadvantages of using BNC over F-Type connectors on coaxial cables

Leokris [45]

Answer:

The benefits and disadvantages of using BNC over F-Type connectors on coaxial cables are;

The <em>benefits </em>of the BNC includes;

1) Easy connect and disconnect for a more rapid connection unlike the F-Type connector which is a screw connector

2) Reduction on stress on the termination of the coaxial cable

3) Appropriate in systems that see frequent reconfiguration unlike te F-Type connector that is permanently attached

4) Prevent unwanted disconnection ensuring image consistency by locking into place

5) Can extend to 300 ft.

The <em>disadvantages</em> of the BNC connectors are;

1) A separate power supply for the cable is required

2) Is used only for video transmission

3) Cannot be used for audio

4) The center wire is not easily visible like those of the F-Type connector which serves as a pin

5) The BNC connector is not watertight like the F-Type connectors

6) There are no provision for properly and securely attaching the cable to the camera for field work such that it can be easily disconnected while in use unlike the F-Type connectors

7) It is not as easy to manufacture like the F-Type connector and it is more expensive

8) The installation of the BNC connector on a coaxial cable is more intricate and the center cable is hidden from view after the BNC is attached thereby making it not possible to see if there is an error in installation which is unlike the F-type connector that takes less than 30 seconds to be attached to a cable

9) The F-Type connector provides more cost savings during installation than the BNC connector

Explanation:

The BNC connector is a type of bayonet connector used more frequently on CCTV systems. The benefits of the BNC includes;

The F-Type connectors are usable on SATV, CATV, and Digital TV where they are used together with RG6 or RG11 cables

The shipping charges per 500 miles are not prorated. For example, if a 2-pound package is shipped 550 miles, the charges would b

Sedbober [7]

Answer:

The solution code is written in Python:

COST_PER_500MI = 1.1
weight = float(input("Enter weight of package: "))
total_cost = weight * COST_PER_500MI
print("The shipping charges is $" + str(round(total_cost,2)))

Explanation:

Based on the information given in the question, we presume the cost per 500 miles is $1.10 per pound ($2.20 / 2 pound).

Create a variable COST_PER_500MI to hold the value of cost per 500 miles (Line 1). Next, prompt user input the weight and assign it to variable weight (Line 3). Calculate the shipping charge and display it using print function (Line 4-5).
