Introduction The Earth is the only planet in the solar system to support life and a major reason behind that is the air on this planet. Air is a mixture of gasses that surrounds the earth and contains oxygen, which is necessary for breathing. This blanket of air also acts as a protective shield against […]
Introduction Various optical systems, including lenses, mirrors, and spherical mirrors, reflect or diverge light to create various kinds of images. Rules of reflection and laws of refraction are the two fundamental laws that govern picture generation. In the creation of images, these laws are crucial. Different-sized pictures are created at various positions when light is […]
Introduction Let’s start with a fascinating experiment that you may have witnessed in your daily life. Insert a pencil or pen into a beaker of water. When you look at the pencil from outside the beaker, what do you notice? It will show up where it shouldn’t be, as you’ll discover. As a result of […]
Introduction An accelerometer is a tool used to measure the acceleration of a body. We are able to monitor and analyse both linear and angular acceleration using the accelerometer’s sensor. This function is used by us in many aspects of daily life and is a requirement for many fundamental systems and gadgets. An accelerometer, which […]
Introduction A conductor’s ability to resist the flow of electric current through it is known as resistance. Resistors are parts that are used to stop the flow of electrons. Due to the attraction between positive particles and negative electrons, the positive conductor particles obstruct the passage of electrons. The flow of electricity is resistant as […]
Introduction Fossil fuels are hydrocarbon (compounds of carbon and hydrogen)-containing substances that form naturally (in nature) on the earth’s surface (earth’s crust). They are made up of the remains of dead (not alive) plants (flora) and animals (fauna) that are extracted (absorbed) and buried under the soil before being burned as fuel. Coal, petroleum, and […]
Introduction Transport is a crucial component of plant physiology and involves moving organic nutrients and water throughout the plant body. Food is produced by photosynthesis in the leaves which is transported to other parts of the plant and water is absorbed from the soil through the roots and then to various aerial regions of the […]
Introduction Evolution is an intricate and slow process. Various organisms constantly adapt by changing their morphological and anatomical characteristics in response to the change in the environmental conditions of their habitat. They make minor changes in their genetic composition to adapt to their surroundings and thrive in their niche. These, minor alterations in their genes […]
Introduction Environmental changes are natural and will continue to occur from time to time. Change can be abrupt or gradual, like climate change and global warming. Because of the changing environment, some creatures become extinct while certain species can thrive with very minor alterations. These modifications are passed down across generations, enabling the species to […]
