The sun, eight planets, moons, numerous dwarf planets (or plutoids), an asteroid belt, comets, meteors, and other objects make up our solar system. Our solar system revolves around the sun, with the planets, their moons, a belt of asteroids, comets, and other rocks and gas orbiting the sun. How far are all the other planets from Earth? Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus, and Neptune are the eight planets that orbit the sun, in order of their distance from the Sun. Pluto, now categorized as a dwarf planet or plutoid, is another huge body. Between Mars and Jupiter is…

Astronomers categorize the planets in our Solar System into two groups: the inner planets and the outer planets. The inner planets are smaller and rockier since they are closer to the Sun. The outer planets are larger, farther away, and primarily formed of gas. Mercury, Venus, Earth, and Mars are the inner planets (in order of distance from the sun, nearest to farthest). The outer planets, Jupiter, Saturn, Uranus, and Neptune, appear after an asteroid belt. The Asteroid Belt, an area of thousands of asteroids orbiting the Sun between Mars and Jupiter, separates the Inner Planets from the Outer Planets.…

The unsung heroes of the modern era are magnets. Most individuals, on the other hand, have no idea what magnets are made of or how they work. The problem is that we only know that iron and nickel are attracted to magnets. Background Image: Unsplash Magnets, on the other hand, have a fascinating history and can be thought of as a physical manifestation of electromagnetic force. Magnets appear to be mysterious. Unseen forces draw magnetic materials together or push them apart with the flip of a single magnet. The attraction or repulsion is proportional to the strength of the magnets.…

An oxidizing agent is a chemical or element that receives electrons from a different species as part of a redox (oxidation-reduction) reaction. An oxidant is a chemical compound that easily transfers oxygen or other atoms in order to get an electron. An oxidizer is a component of a process that releases oxygen or acquires electrons or hydrogen. As it absorbs electrons, the oxidizer is decreased. The reactant, on the other hand, is oxidized by allowing its electrons to be acquired by the oxidizer. Oxygen is the eponymous example of an oxidizing agent. Oxidizing agents are also referred to as oxidizers…

The sun rises every morning, bringing light and warmth to the earth, and sets every evening. We rarely think about that brilliant object in the sky since it appears to be so usual. We wouldn’t exist if it weren’t for it! The Ultimate Source of Energy Nuclear fusion occurs deep into the core of our local star (yes, the sun is a star–a BIG star!). They generate a tremendous quantity of energy that travels at the speed of light (more than 186,000 miles per second). That energy travels 93 million miles to earth in under eight minutes. We use many…

A bond, also known as a chemical bond, is a connection between atoms in molecules or compounds, as well as between ions and molecules in crystals. A bond represents a permanent attraction between distinct atoms, molecules or ions. The attraction between two opposite electrical charges can explain the majority of bonding activity. An atom’s or ion’s electrons are drawn to their own positively charged nucleus (which contains protons), as well as the nuclei of neighbouring atoms. When chemical bonds are formed, species that participate in them are more stable, usually, because they have an imbalance of charge (more or fewer…

Candidates for a Physics PhD program are often graduates of previous degree programs in mathematics and science that offered a sufficient foundation of knowledge. Condensed matter physics, atomic physics, molecular physics, optical physics, geophysics, biophysics, high energy/particle physics, and astrophysics are some of the specialities available in physics PhD programs. Engineering, product development, consulting, teaching, and other fields might benefit from the theoretical training and abilities learned in a Physics PhD program. Although applied physics is the field of study that is designed for practical application, all Physics PhD topics are regarded as valuable contributions to our understanding of the…

When we go out in the summer to enjoy the pools and rivers, we must constantly double-check that all of our equipment and safety precautions are in place and operational. What is Specific Gravity? When we go to the river and board our boats, we make sure there are no leaks and that we are wearing our life jackets. We make sure that young children who are still learning to swim have their floaters on or swim with them in a swim ring to ensure that they do not sink. Why do both boats and swimming rings float? One of…

The meaning of velocity for an object is the rate at which the object’s position changes in relation to a frame of reference and time. It may sound difficult, but velocity simply refers to the rate at which something moves in a given direction. It is a vector quantity, which means that to define velocity, we need both magnitude (speed) and direction. It has the SI unit of meter per second (ms-1). When the amount or direction of a body’s velocity changes, the body is said to be accelerating. Velocity and Acceleration Image: Unsplash To put it another way, it’s…

In 2020, spaceflight did not proceed as planned. Space activity, like practically everything else in the world, was severely impacted by the pandemic. Last year, SpaceX launched astronauts into space! China has returned moon rocks to Earth! However, a number of other things didn’t happen: the Rosalind Franklin rover for Europe and Russia was postponed until 2022. The SpaceX Starship was not launched into orbit (though it did go high). By the time the virus shut down most of NASA’s facilities, any remaining expectations that Artemis 1, the first mission in NASA’s new lunar exploration program, which is supposed to…
