Answer:
The solution code is written in Python 3
- import random
- import string
-
- def simulate_several_key_strikes(l):
- char_set = string.ascii_lowercase
- return ''.join(random.choice(char_set) for i in range(l))
-
- print (simulate_several_key_strikes(10))
Explanation:
The program is aimed to generate random characters and the number of characters generated is dependent on user input. Hence, we will need to import the random module (Line 1). We also import string module so that we can make use of its associated method to generate English letters (Line 2)
Next, we create the function simulate_several_key_strikes that takes one single parameter, l, as input. Within the function body, we use ascii_lowercase method to generate the lowercase letter set and assign it to char_set variable (Line 5). We use random.choice method to randomly pick one of the letter in char_set and join it with an empty string (Line 6). Please note there is a for-loop that will repeatedly generate l-number of character and eventually return it as output.
We test the function by passing 10 as input parameter and we shall get a sample output as follows:

Answer:
the Telephone
Explanation:
Before the invention of electromagnetic telephones, mechanical acoustic devices existed for transmitting speech and music over a greater distance greater than that of normal direct speech. The earliest mechanical telephones were based on sound transmission through pipes or other physical media.The acoustic tin can telephone, or "lovers' phone", has been known for centuries. It connects two diaphragms with a taut string or wire, which transmits sound by mechanical vibrations from one to the other along the wire (and not by a modulated electric current). The classic example is the children's toy made by connecting the bottoms of two paper cups, metal cans, or plastic bottles with tautly held string.Some of the earliest known experiments were conducted by the British physicist and polymath Robert Hooke from 1664 to 1685. An acoustic string phone made in 1667 is attributed to him.For a few years in the late 1800s, acoustic telephones were marketed commercially as a competitor to the electrical telephone. When the Bell telephone patents expired and many new telephone manufacturers began competing, acoustic telephone makers quickly went out of business. Their maximum range was very limited. An example of one such company was the Pulsion Telephone Supply Company created by Lemuel Mellett in Massachusetts, which designed its version in 1888 and deployed it on railroad right-of-ways.Additionally, speaking tubes have long been common, especially within buildings and aboard ships, and they are still in use today. The telephone emerged from the making and successive improvements of the electrical telegraph. In 1804, Spanish polymath and scientist Francisco Salva Campillo constructed an electrochemical telegraph.The first working telegraph was built by the English inventor Francis Ronalds in 1816 and used static electricity. An electromagnetic telegraph was created by Baron Schilling in 1832. Carl Friedrich Gauss and Wilhelm Weber built another electromagnetic telegraph in 1833 in Göttingen.At the University of Gottingen, the two have been working together in the field of magnetism. They built the first telegraph to connect the observatory and the Institute of physics, which was able to send eight words per minute.
