Introduction There can be many types of motion exerted by a body like translational motion, rotational motion, circular motion, uniform motion, etc. In rotational motion, rigid bodies which have a definite size and definite shape are considered. The particles present in a body about a fixed axis move in a circular path. So to understand the concept of rotational motion you must know about circular motion. Here the terms are included in angular form. What is Rotational Motion? If a force is applied to any object at the corner side of it(not on the centre of mass), then we see ... Read More

Introduction The world around us is filled with interesting objects. Some are very heavy and some are very light. Some objects swiftly let the electricity and heat pass through them, and some resist. Some materials attract objects of iron. These are called magnetic materials. We all have played with a piece of magnet in childhood. Refrigerator magnets were very popular among kids. An object which can create a magnetic field is known as a magnet. Initially, the natural magnets were known as lodestones. They can be compared to the electric charge. As the electric charge creates the electric field and ... Read More

Introduction Electricity is one of the most used things by humans. It is transported from the powerhouse through the wires to the various houses and industrial locations. Electric current has two main types - Direct current and Alternating current. Alternating current mainly flows in the wires which see around us. Electricity has given new dimensions to power systems and technology, however, it can be dangerous also. Spark in electrical wires can lead to a fire. If touched directly, live wires can also give shocks. Keeping these things in mind, for the safety of humans and the powerhouses we used several ... Read More

Introduction In our day-to-day life we observe various phenomena like after the rain a rainbow is formed in the sky, splitting of white light into seven colors, and when water falls on petrol it also shows different colors. These all phenomena are related to the optical phenomenon of light. In this tutorial, we will discuss the two important phenomena i.e. diffraction and interference. In classical physics, the term diffraction is firstly explained by using the Huygen-Fresnal principle. After this various Scientists make different attempts to explain these terms in their way. It finds applications in the study of biological ... Read More

Introduction Energy and work are measured in joules. By applying a force of one newton over a distance of one meter, an object is made to work (or to be energized). One joule is produced when an object is subjected to a force of 1 N and moves 1 m. Newton meters are used to measure it. The exact equivalent of heat is produced each time mechanical force is applied. The heat generated in any electrical component varies directly to the squared current, the resistance, and the duration of the current's flow, as per Joule's law of heating. What ... Read More

Introduction You must have come across the term energy quite often while studying any branch of science. And even without much scientific information, you must have an understanding of what energy is. A person without scientific information may think of energy as some sort of property that allows objects to function. For example, energy makes our cars' engines go, and energy can illuminate light bulbs. However, the scientific view of energy is a little more complex and far more widespread than one might be inclined to think. What is Energy? The scientific definition of energy may be stated as follows: ... Read More

Introduction John Dalton believed that an atom is the smallest microscopic particle contained in a substance. John Dalton does not study microscopic particles in solids. Instead, he mostly studied the particles of gases. Even though J.J. Thomson explained the neutral nature of atoms, he was unable to explain the concept of the nucleus in the atom. In 1909, Ernest Rutherford introduced a new theory of nuclear power. Ernest Rutherford, a British physicist, was involved in the study of atoms through radioactive probes using alpha particles. Rutherford’s atomic model is modified by Niels Bohr. The stability of the atom ... Read More

Check a Subarray is Formed by Consecutive Integers from a Given Array in Java

Updated on 30-Jan-2023 16:49:28
In Java, Array is an object. It is a non-primitive data type which stores values of similar data type. As per the problem statement we have to check if a sub array is formed by consecutive integers from a given array of integers. The sub array refers to some segment of the array from an array. Here it has been told to check the subarray formed by consecutive integers elements i.e., the array elements are a set of continuous numbers where we can get one after another element. Let’s explore the article to see how it can be done by ... Read More
