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 […]
What are the sources of thermal pollution?
What are the sources of thermal pollution? Some of the important sources of thermal pollution are nuclear power and electric power plants, crude oil refineries, steel melting factories, coal fire power plant, boiler from industries which release large amount of heat to the water bodies leading to change in the physical, chemical and biological characteristics […]
Are there P waves in atrial fibrillation?
Are there P waves in atrial fibrillation? Atrial fibrillation is the most common chronic arrhythmia, characterized by erratic atrial electrical activity with atrial rates of 400 to 600 beats per minute. The P wave is absent on the surface electrocardiogram and can, at times, be replaced with “fibrillatory waves.” How do I know if I […]
Why does river discharge increase downstream?
Why does river discharge increase downstream? Changes Downstream As one moves along a stream in the downstream direction: Discharge increases, as noted above, because water is added to the stream from tributary streams and groundwater. As discharge increases, the width, depth, and average velocity of the stream increase. Why are river profiles concave? River profiles […]

What role do planetesimals play in the origin of the planets?
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 […]
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 […]
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 […]
How do you write an effective peer review?
How do you write an effective peer review? Do Justify your recommendation with concrete evidence and specific examples. Be specific so the authors know what they need to do to improve. Be thorough. This might be the only time you read the manuscript. Be professional and respectful. Remember to say what you liked about the […]
Do inertial frames exist?
Do inertial frames exist? Such a frame is called an inertial frame. If one such inertial frame exists, then an infinite number of other inertial frames exist since any frame that is moving at a constant relative velocity to the first inertial frame is also an inertial frame. They are called non-inertial frames. Is Earth […]
