What is gravitational equilibrium? Hydrostatic equilibrium, also known as gravitational equilibrium, describes a balance between gravity and pressure. Gravity works to contract while pressure works to expand. Hydrostatic equilibrium is the state where the force of gravity pulling inward is balanced by pressure pushing outward. What is heating the corona? The coronal heating problem in […]

What is metal ductility? Material properties Ductility is the ability of a material to be drawn or plastically deformed without fracture. It is therefore an indication of how ‘soft’ or malleable the material is. The ductility of steels varies depending on the types and levels of alloying elements present. Is all metals are ductile? Answer […]

How do you check if your immune system is strong? Your body shows signs of a strong immune system pretty often. One example is when you get a mosquito bite. The red, bumpy itch is a sign of your immune system at work. The flu or a cold is a typical example of your body […]

Why do people put their wheels under a heavy box? Why does placing wheels under a heavy box reduce the necessary force required to push it along at a constant speed? The wheels are causing less friction between the ground and the box. In order to push it, less force is needed. When the brake […]

What is the dimensional formula for gas constant? Or, G = [M1 L-1 T-2] × [L3] × [K1]-1 = [M1 L2 T-2 K-1]. Therefore, the gas constant is dimensionally represented as [M1 L2 T-2 K-1]. What is the dimensional formula of Boltzmann constant? Or, k = [M1 L2 T-2] × [M0 L0 T0 K1]-1 = […]

What does the flat part of a heating curve indicate? Heating curves show how the temperature changes as a substance is heated up. Cooling curves are the opposite. They show how the temperature changes as a substance is cooled down. Just like heating curves, cooling curves have horizontal flat parts where the state changes from […]

How does culture affect workplace? Workplace culture in an important factor to all workplaces. It determines how pleasant or toxic your work environment is. It has a direct influence on how your employee fits into the organisation and your organisation’s ability to attract and retain employees because it shapes the environment that they work in. […]

Who is the father of India? Mahatma Gandhi What is the 1st language? As far as written languages go, Sumerian and Egyptian seem to have the earliest writing systems and are among the earliest recorded languages, dating back to around 3200BC. But the oldest written language that is still in actual use would probably be […]

Can a comet become a meteor? Comets: Comets are dirty space snowballs of mostly ice and dust that formed during the birth of the solar system 4.6 billion years ago. Most comets have stable orbits in the outer reaches of the solar system past the planet Neptune. When meteoroids collide with a planet’s atmosphere, they […]

Who gives the equation of motion? Galileo and the Equations of Motion. The first of the three laws of motion formulated by Newton (1642-1726) says that every object in a state of uniform motion remains in that state unless an external force is applied. This is essentially a reformulation of Galileo’s inertia concept. What are […]
