What role do planetesimals play in the origin of the planets? A planetesimal is small bodies from which a planet originated in the early stages of formation of the solar system. Protoplanets are when planetesimals join together through collisions and through the force of gravity to form larger bodies. Because they have their gases they […]
How is China doing on climate change?
How is China doing on climate change? China, along with 196 countries, agreed to help reduce rising global temperatures and set a goal temperature of 1.5 degrees celsius above pre-industrial temperatures. China has agreed to its NDC goal of reducing the CO2 intensity of its gross domestic product by 60% by 2030. What countries contribute […]
What is simple harmonic motion write its any four characteristics?
What is simple harmonic motion write its any four characteristics? (i) In SHM, acceleration of the particle is directly proportional to its displacement, and directed towards the mean position. (ii) It can be represented by a single harmonic function of sine or cosine. (iii) Total energy of the particle executing SHM remains conserved. (iv) It […]

Is 100 degrees Celsius hot?
Is 100 degrees Celsius hot? No. We can say that the temperature of boiling water is 100°C(or 100 K) more than the temperature of ice cold water. The highest temperature obtained in the large hadron collider is 5.5 trillion degrees Celsius while the temperature on the surface of sun is 5600°C. However, sun has much […]
What is the difference between successful people and normal people?
What is the difference between successful people and normal people? Ordinary people set goals, successful people set detailed plans of actions. Successful people set their goals as well. More importantly, however, they create a detailed set of actions they need to perform in order to achieve their end goal. What is the difference between ordinary […]
What is the law of conservation of momentum give an example?
What is the law of conservation of momentum give an example? Conservation of Momentum Examples According to the conservation of momentum, the gun receives a backward momentum. The bullet of mass m is fired with forward velocity v. The gun of mass M acquires a backward velocity u. Before firing, the total momentum is zero […]
Are aluminum bats allowed in Major League Baseball?
Are aluminum bats allowed in Major League Baseball? Aluminum bats are used in college, high school and little league ball, but they’re illegal in the major leagues where hitters must use wooden bats. The issue is the velocity with which balls come off the bat, otherwise known as bat-exit speed. Where do you bat your […]
What happens to current during charging and discharging of a capacitor?
What happens to current during charging and discharging of a capacitor? Ans: During the process of charging the capacitor, the current flows towards the positive plate (and positive charge gets added to that plate) and away from the negative plate. While during the discharging of the capacitor, current flows away from the positive and towards […]
How is cubical expansion calculated?
How is cubical expansion calculated? “VOLUMETRIC EXPANSION ” or “CUBICAL EXPANSION”. Consider a metallic body of volume = V1 . Let it’s temperature is raised by T. then experimentally “Increase in volume ( V) is directly proportional to its initial volume (V1) and rise in temperature ( T). What is an example of anomalous Behaviour […]
