At 400 K and 200 K, correspondingly, the heat engine's maximum efficiency is 50%.
What is the heat engine efficiency formula?
efficacy is WQH=1TC/TH. The efficiency of a Carnot engine with a hot reservoir of boiling water and a cold reservoir of freezing cold water, for instance, will be 1(273/373)=0.27, or little over 25% of the heat energy is transformed into usable work. Of course, these temperatures are in degrees Kelvin.
Due to that,
The hot reservoir's temperature is 400 K.
Cold reservoir temperature is 200 K.
We must determine the most effective solution.
Efficiency =WQH=1-TC/TH
is the formula for the heat engine's efficiency.
Add up all the numbers, and use efficiency = 1 - (200/400).
Efficiency is equal to 50% or 0.5.
hence, The heat engine has a 50% efficiency.

Create a new int pointer called first that holds the first address of the array numbers.
This is an example in C++ language that demonstrates how to create a pointer called "first" to hold the first address of an array called "numbers", and how to print this same array elements using pointer "first".
Coding Part in C++ Programming Language:
#include <iostream>
using namespace std;
int main() {
int numbers_xyz[] = {1, 2, 3, 4, 5};
int* first = &numbers_xyz[0];
for (int mx = 0; mx < 5; mx++) {
cout << *(first + mx) << endl;
}
return 0;
}
This program creates an array numbers with 5 elements, then creates a pointer first that holds the address of the first element in the array (numbers[0]).
The program then uses a for loop to iterate over the elements of the array and print them out, using the pointer first to access each element. The * operator is used to dereference the pointer and obtain the value stored at the memory location pointed to by the pointer.

A student has recorded a 30 second digital sound track using a sample rate of 44 000Hz. 8 bits have been used to store each sample taken.
Calculate the file size in kilobytes of the digital sound track.
The file size in kilobytes of the digital sound track is 10,560 kilobits.
What is digital sound track?Music that has either been digitally recorded or transformed. The term "digital music" is frequently used to refer to music in MP3 and other compressed music forms obtained over the Internet, even though the compact disc (CD) was the first digital music format.
Both the literary term "diegesis" and the adjective "diegetic" are used to categorize film music and movie soundtracks. The context in which a piece of music is utilized determines whether it is one or the other.
Because we divided the result by 8, the calculated file size will be in bytes, the sampling frequency will be in hertz, the bit depth will be in number of bits, and the length will be in seconds.
We know that,
File size = (sampling frequency x bit depth x length)
File size = 44 000 x 30 x 8
File size = 10560,000 bits = 10,560 kilobits

What does "average angular velocity" mean?
The ratio of the change in time to the change in the angular coordinate, expressed in radians, is known as the average angular velocity. A vector pointing in the direction of the rotational axis is the angular velocity.
The answer to the question is,
that the ball's angular velocity is given by,
ω = Δθ/Δt
The ball makes 2 revolutions in 0.95 seconds, and each revolution results in a change in angular position, thus = 2. Consequently,

It is False, python does not format all floating-point numbers to two decimal places when outputting with the print statement. Use the string formatting operator (%) if that's what you want to accomplish.
Python does not automatically format floating-point integers to two decimal places when using the print statement.
In Python, there are four alternative techniques to format strings:
• Using the formatting operator %.
• Using the format() string function for formatting.
• Formatting using f-strings, a type of string literal.
• String Template Class formatting.
String formatting is the process of dynamically adding items to a string and presenting it.
A new string formatting method introduced in Python 3 was later backported to Python 2.7. The %-operator special syntax is eliminated by this "new style" string formatting, which also regularises the syntax for string formatting. A string object can now be formatted by invoking the function.format().
Formatted string literals, sometimes known as "f-strings," are a new string formatting technique introduced in Python 3.6. You can now use embedded Python expressions inside of string constants thanks to this new method of formatting strings.
Template strings are a further tool for formatting strings in Python.
