Java is a class-based, object-oriented, general-purpose programming language made to have fewer implementation dependencies. It is a computing platform for developing applications. As a result, Java is fast, safe, and dependable. In laptops, data centers, game consoles, scientific supercomputers, mobile phones, and other devices, it is frequently utilized for the development of Java applications.

The Java Platform is a set of programs that make it easier for programmers to create and run Java applications effectively. It has a compiler, an execution engine, and a collection of libraries. It consists of software and specifications for computers.

Answer: (read explanation)

Explanation:

Symmetry and rigid transformations are related in that symmetry is a type of rigid transformation. A rigid transformation is a type of transformation in geometry in which the shape of an object is preserved after the transformation is applied. This means that the distances between all points on the object remain the same, and the angles between those points are also unchanged.

Symmetry is a specific type of rigid transformation that involves a reflection, rotation, or translation of an object such that the resulting image is congruent to the original. In other words, symmetry is a type of transformation in which an object is mapped onto itself in a way that preserves its shape and size.

For example, if an object has rotational symmetry, it means that it can be rotated by a certain angle and the resulting image will be congruent to the original. If an object has reflectional symmetry, it means that it can be reflected across a certain line and the resulting image will be congruent to the original.

Overall, symmetry is a type of rigid transformation in which an object is mapped onto itself in a way that preserves its shape and size. This type of transformation is related to other types of rigid transformations, such as rotations and translations, which also preserve the shape and size of an object.

if the maximum load capacity (or buckling load) of column 1 (fixed-fixed) is 100 kn, the load capacity (or buckling load) of column 2 (fixed-free) will be = 1.56kN.

Buckling is simply the out-of-plane bending of a vertical compression member. The slenderness of the vertical compression member is typically to blame. This phenomenon is clearly explained by Euler, who has provided elaborate formulas to determine the actual amount of buckling in the compression member.

The compression member may be a column (long, short, or medium), a built-up steel member with a slender web, a readily available steel member with a slender web, etc. For various support situations, different buckling conditions exist. The terms "buckling load" and "crushing load" are interchangeable. We must fortify the slender member to prevent buckling.

[tex]p_3[/tex] = water density = 1000 kg/m^3

[tex]p_4[/tex] = mercury density = 13600 kg/m^3

Since the ethanol is exposed to air and the manometer also exposed to air, we can determine the height of mercury is equal by extra pressure by liquid. So,

[tex]p_4[/tex]*g*h = [tex]p_1[/tex]*g*0.1+[tex]p_2[/tex]*g*0.1+[tex]p_3[/tex]*g*0.2

we can eliminate the g or gravity.

13600h = 789*0.1+918*0.1+1000*0.2

13600h = 78.9+91.8+200

What is function?
Function is a block of code that performs a specific task. It is a sequence of statements that are written for a particular purpose and can be called upon when needed. Functions allow for code to be reused, making it easier to debug and maintain programs. They also help to reduce the amount of code needed in a program by allowing for code to be broken down into smaller, more manageable pieces. Functions can take parameters, which are pieces of data that are passed to the function when it is called. By passing parameters, the same function can be used with different data, making it more versatile. Functions can also return values, which are pieces of data that are sent back to the program once the function has completed its task. Functions can be written in any programming language, and are an important part of programming.
