An Olympic-size swimming pool is used in the Olympic Games, where the race course is 50 meters (164.0 ft) in length. "In swimming a lap is the same as a length. By definition, a lap means a complete trip around a race track, in swimming, the pool is the race track. Therefore if you swim from one end to the other, you’ve completed the track and thus you’ve completed one lap or one length." (Source: What Is A Lap In Swimming? Lap Vs Length)
Write the function meters_to_laps() that takes a number of meters as an argument and returns the number of laps. Complete the program to output the number of laps.
Output each floating-point value with two digits after the decimal point, which can be achieved as follows:
print('{:.2f}'.format(your_value))
Ex: If the input is:
150
the output is:
3.00
Ex: If the input is:
80
the output is:
1.60
Your program must define and call the following function:
def meters_to_laps (length)
Answer:
In Python:
def meters_to_laps(length):
lap = length/50
print('{:.2f}'.format(lap))
Explanation:
This line defines the function
def meters_to_laps(length):
This calculates the number of laps
lap = length/50
This prints the calculated number of laps
print('{:.2f}'.format(lap))
To call the function from main, use:
meters_to_laps(150)

Online, it is easy to think of communication as “computer to computer” rather than “person to person”. Thus, option D is correct.
What is communication?It is possible to describe communication as the act of passing the information between one person or group of people to the next. Communicating facilitates easy understanding of what a different person is trying to say or convey. There are two forms of communication: both verbal and nonverbal.
With the help of communication the person can tell and feature tthe data between the person and an group. In this, that data is given to the people and the data is not given to the person but it is rather given to the person. As this data is been transferred from one computer to another and then it reaches the people.
Therefore, option D is the correct option.

Answer:
Follows are the code to the given question:
#include <stdio.h>//header file
int main()//main method
{
int count=0;//defining an integer variable
for(count=0;count<3;count++)//use for loop to count values
{
printf("%d\n",count);//print count values
}
return 0;
}
Output:
0

2
Explanation:
In this code, it declares the integer variable "count" which has a value of "0" and in the next step declares a loop, using the count variable to regulate count values, which is less than 3, and increases the count value, and prints its values. This variable is the count value.
The count variable holds a value of 0, and use a for loop that checks its value is less than 3, and print its value, that's why it will print the value that is 0,1, and 2.
Explanation historical development of computer
Answer:
Brief History Of Computer. The computer as we know it today had its beginning with a 19th century English mathematics professor name Charles Babbage. ... Other developments continued until in 1946 the first general– purpose digital computer, the Electronic Numerical Integrator and Computer (ENIAC) was built.
Explanation:
Computers and electronics play an enormous role in today's society, impacting everything from communication and medicine to science.
Although computers are typically viewed as a modern invention involving electronics, computing predates the use of electrical devices. The ancient abacus was perhaps the first digital computing device. Analog computing dates back several millennia as primitive computing devices were used as early as the ancient Greeks and Romans, the most known complex of which being the Antikythera mechanism. Later devices such as the castle clock (1206), slide rule (c. 1624) and Babbage's Difference Engine (1822) are other examples of early mechanical analog computers.
The introduction of electric power in the 19th century led to the rise of electrical and hybrid electro-mechanical devices to carry out both digital (Hollerith punch-card machine) and analog (Bush’s differential analyzer) calculation. Telephone switching came to be based on this technology, which led to the development of machines that we would recognize as early computers.
The presentation of the Edison Effect in 1885 provided the theoretical background for electronic devices. Originally in the form of vacuum tubes, electronic components were rapidly integrated into electric devices, revolutionizing radio and later television. It was in computers however, where the full impact of electronics was felt. Analog computers used to calculate ballistics were crucial to the outcome of World War II, and the Colossus and the ENIAC, the two earliest electronic digital computers, were developed during the war.
With the invention of solid-state electronics, the transistor and ultimately the integrated circuit, computers would become much smaller and eventually affordable for the average consumer. Today “computers” are present in nearly every aspect of everyday life, from watches to automobiles.
The history of computers is one that began far back 2000 years ago in the city of Babylonia where there was the use of abacus and it has grown to now the use of digital computer as it start in 1642.
What is the history of computer?The history of computers is one that is more than 200 years but in the 19th century, there was the invention of mechanical calculating machines.
Note that the The 1st generation of computers was said to have existed from the year 1940 to 1955 and now it has grown to a whole new level.
