The term biodiversity describes the great variety of life on Earth. Biodiversity refers to the variety of living things, including plants, animals, and microorganisms. We don't know for sure exactly how many different organisms there are on Earth. However, scientists estimate that there are about 8-14 million (80 to 140 lakh) different species of organisms on this Earth. Some believe that the number is higher. But whatever the number, most of these organisms are unknown to us. Only 1.2 million (12 lakh) species have been identified and described so far, most of which are insects. This means that billions of other organisms are still mysterious and unknown to us. Origin of Biodiversity The unique characteristics of all sp

Electromagnetic Induction and Alternating Current

Electromagnetic Induction and Alternating Current Notes for Class 11 - 12 Learning Outcomes Electromagnetic Induction Generating Electricity with Magnet Induced Electromotive Force Faraday's Laws of Electromagnetic Induction Lenz's Law Lenz's Law and Conservation of Energy Self Induction and Mutual Induction Generating of Alternating Current Root Mean Square Value, Peak Value and Current Electromagnetic Induction The process of inducing temporary electromotive force or electricity by means of a moving magnet or current-conducting coil in a closed circuit is called electromagnetic induction. Electromagnetic induction is a phenomenon discovered by Michael Faraday in the 19th century, which explains the relationship between electricity and magnetism. It refers to the production of an electrical voltage or current in a conductor as a result of a changing magnetic field in its vicinity. This process is the basis of many important technological applications, including electric ge

The Importance of Information and Communication Technology

The Importance of Information and Communication Technology Information and Communication Technology (ICT) refers to the use of technology to manage and exchange information. In the modern world, ICT has become an indispensable tool for individuals, businesses, and organizations alike. Its impact on society has been significant, leading to the creation of new opportunities, improved efficiency, and increased connectivity. One of the key benefits of ICT is the increase in efficiency that it has brought about. With the help of technology, information can be processed, analyzed, and shared more quickly and accurately than ever before. This has led to improved productivity and a more streamlined workflow. For example, businesses are now able to automate repetitive tasks and focus on more important tasks, leading to more efficient use of time and resources. Additionally, ICT has enabled the creation of virtual work environments, which has allowed individuals to work remotely and busines

When you open the gas cylinder used for cooking, which action takes place first diffusion or effusion?

When you open the gas cylinder used for cooking, which action takes place first diffusion or effusion? The pressures of the ingredients of body spray inside and outside of the container are not the same. The pressure is greater inside the container. When the molecules of the gas come out through small pores into a low-pressure zone from a high-pressure zone, effusion happens. Due to the application of pressure, the molecules present in body spray come out through the small pores. The spontaneous movement is blocked by the pore of the container. The bigger the pore size, the more spontaneous the movement is. When the condition becomes absolutely pressure-less, it becomes diffusion. So in the case of a body spray, first effusion takes place, then diffusion happens. When you open a gas cylinder used for cooking, effusion takes place first. Effusion refers to the process of a gas molecule escaping through a small opening, such as a hole in a container, into a surrounding environment wi

Information and Communication Technology Questions and Answer What is Global Village? The term "global village" refers to the idea that the world has become interconnected and interdependent as a result of advances in communication technology, transportation, and globalization. This term implies that the world has become a smaller place, where people can communicate and interact with each other in real time, regardless of geographical distance. The term was popularized by Canadian media theorist Marshall McLuhan in the 1960s, and it has since been used to describe the growing interconnectedness of the world through the Internet, social media, and other digital technologies. The global village concept has both positive and negative implications. On the positive side, it promotes communication, collaboration, and cultural exchange on a global scale. On the negative side, it also exacerbates economic and social inequalities, as well as environmental degradation, as countries a

Why is the value of g is different in polar, equinoctial and the tropical regions?

Why is the value of g is different in polar, equinoctial, and tropical regions? As the earth is not perfectly round, the polar regions are a bit compressed, therefore the radius of the earth R is not constant. Hence the value of g is not the same at all places on earth. The value of g is different in different places on earth. The value of g is highest in the polar region and it is 9.83217 ms -2 . In the equinoctial region, it is 9.78039 ms -2  and in the tropical region, it is 9.78918 ms -2 . Its value at sea level altitude of 45 degrees is accepted as the standard value. The standard value of g is 9.80665 ms -2 . For convenience, the standard value of g is taken to be 9.8 ms -2  or 9.81 ms -2 .

What is an induction stove?

Image
What is an induction stove? In an induction stove, a cooking vessel is placed on top of a coil of copper wire with an alternating electric current passing through it. The resulting oscillating magnetic field wirelessly induces an electrical current in the vessel. This large eddy current flowing through the resistance of the vessel results in resistive heating. How does induction cooking work? The flow of an alternating current (AC) creates an electromagnetic field on an induction stovetop that excites the molecules in pots and pans that aren’t good conductors, like iron or steel. When these metal molecules are excited, they heat up quickly. They also cool down quickly. You won’t see the stovetop glow red like you might a standard electric stovetop. And when the molecular connection between cookware and the stovetop is broken, the heat stops being produced. You may like What is a generator? What is the function of a generator?

What is photosynthesis?

What is photosynthesis? Photosynthesis is the process by which green plants, algae, and some bacteria convert light energy from the sun into chemical energy stored in the form of organic compounds, such as glucose. This process involves the use of light energy, water, and carbon dioxide to produce oxygen and carbohydrates. In plants, photosynthesis takes place in specialized organelles called chloroplasts, which contain chlorophyll, the pigment that gives plants their green color. Chlorophyll absorbs light energy from the sun, which is used to convert carbon dioxide and water into glucose and oxygen. The overall chemical equation for photosynthesis is: 6CO2 + 6H2O + light energy → C6H12O6 + 6O2 This process is essential for life on Earth, as it provides the basis for the food chain and is responsible for producing the oxygen we breathe. Additionally, photosynthesis plays an important role in regulating the Earth's climate by removing carbon dioxide from the atmosphere and releasing
