In Java, a multi-dimensional array is nothing but an array of arrays.2D array − A two-dimensional array in Java is represented as an array of one-dimensional arrays of the same type. Mostly, it is used to represent a table of values with rows and columns −Int[][] myArray = {{10, 20, 30}, {11, 21, 31}, {12, 22, 32} }In short, a two-dimensional array contains one-dimensional arrays of elements. It is represented by two indices where the first index denotes the position of the array and the second index represents the position of the element within that particular array − Example ...

Introduction Multiplication is a mathematical operation or process of combining the total number of items or values by using repeated addition. It is used in all sections of mathematical problem solutions be it Algebra, Arithmetic, Trigonometry, Coordinate Geometry, Calculus and etc. Multiplicand and Multipliers When we apply multiplication then, the Multiplicand is the number which is being multiplied and the Multiplier is the number which is multiplying the first number. For example: In this multiplication 20 is the Multiplicand and 25 is the Multiplier. Multiplication Tricks A single-digit number can be easily multiplied. But the multiplication of ... Read More
Introduction In engineering, we come across various systems where the process depends on more than one variable. In this case, the optimization and designing of the system need the involvement of multiple variables. In this direction, multivariable calculus plays an important role. It has various applications starting from economics to science. In this tutorial, we will learn about multivariable calculus and its various operations (such as limits, continuity, partial derivatives, and integration) with solved examples. What is meant by Multivariable Calculus Multivariable calculus is an extended topic of calculus that includes multiple variable functions. ... Read More
Introduction The solutions of the quadratic equation ax2+bx+c=0 serve as the quadratic equation's roots. They are the values of the variable x that the equation requires. The x-coordinates of the x-intercepts of a quadratic function are the roots of the function. A quadratic equation can only have a maximum of two roots because its degree is 2. The nature of these roots of the quadratic equation is solely dependent on the value of the determining factor which is called a discriminant of the quadratic equation about which we will be discussing in this tutorial. Quadratic Equation ... Read More
Introduction In non-terminating decimals, the numbers after the decimal point tend to be endless. In the non-terminating repeating decimals, a sequence of numbers after the decimal point is recurring in a specific pattern. These types of numbers are called Rational numbers. They are in $\mathrm{\frac{p}{q}}$ where q ≠ 0. In non-terminating decimals we will be discussing irrational numbers which cannot be represented in fractions. Whereas, if the non-terminating decimals have recurring patterns then it is said these decimals can be converted into fractions. In this tutorial, we will learn about non-terminating repeating decimals and how to ... Read More
Introduction Dispersion force arises because of the fluctuation in the polarizability. It is a temporary effect. The noble gases that don't form any chemical bonds are attracted to each other and condense to liquid form at low temperatures. So, atoms also have a type of attraction. Fritz London, an Austrian physicist in 1930 introduced a theory that states that when two molecules approach each other the flow of electrons or the movement of electrons in one molecule will interfere with the electron movement in the other molecule. And they are by resulting in an attractive force. For a better understanding ... Read More
Introduction Einsteinium-253, which has a half-life of 20.5 days, was created after several uranium atoms captured numerous neutrons and underwent a sequence of capture and decay steps. Since 𝐸𝑠 is artificial, neither does it exist in nature nor on the earth's surface. It is created in small amounts through thermonuclear bomb explosions or artificially induced spontaneous transmutations of specific radioactive elements. On 1 November 1952, the thermonuclear explosion, which occurred on a Pacific atoll, left behind debris that contained the element Einsteinium. A neighbouring atoll's fallout material was shipped to Berkeley, California, for analysis. Stanley Thompson, Gregory Choppin, Albert Ghiorso, ... Read More
Introduction By combining the words "electrolyte" and "conduction" or "conductors, " the phrase "electrolytic conductance" is created. It is crucial to first realize what each of these terms means. A material that generates electricity when dissolved in a polar solvent like water is known as an electrolyte. These electrolytes cannot conduct electricity in a solid state; they must be watery or molten. Electrolysis is the process of dissolving these compounds in a solvent while an electric current is flowing. "Conductance" or "conductor" is the second most crucial word for electrolytic conductance. To gain an understanding of more complex subjects like ... Read More
Introduction Stearic acid is present in the fats of animals and plants and used in food products that help treat or reduce eczema symptoms, skin inflammation and help retain the skin's moisture. Cosmetics products including stearic acid must be used after consulting a skin doctor or dermatologist to avoid the side effects like irritation, rashes, or severe cream burn on skin. What is Stearic acid? The saturated long-chain fatty acid is made up of 18 backbone of carbon and is referred to as stearic acid. The acid can be found in several types of fats of plants and animals. Stearic ... Read More
Introduction “Strontium” is a chemical element that is symbolised by “Sr” and it has an “atomic number 38”. An “alkali earth metal” has a unique “silver white-yellowish” appearance. It is quite strongly chemically reactive. It is naturally non-radioactive and it creates a “dark oxide layer” upon exposure to the air. Physically and chemically, this element is quite similar to “calcium and barium” What is “Strontium”? “Strontium” mostly exists naturally in “rocks coal and oil” as a “non-radioactive element”. 99% of “strontium” is found in the bones of human body. It exists in the form of four stable isotopes in ... Read More
