What kind of charging occurs when you slide your body across a plastic surface?
What kind of charging occurs when you slide your body across a plastic surface? Electrostatics: When a person slides across a plastic surface, the plastic produces a net negative charge and your body surface a net positive charge. What will happen if you switch the battery so that the positive end is on the right […]
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 […]

Why does high pressure bring clear weather?
Why does high pressure bring clear weather? The absence of wind in high pressure is due to the lack of an air-pressure gradient. Because rising air cools and results in the condensation of water vapor, which is the reason for clouds and precipitation, downward-moving air and high pressure usually brings mostly clear skies. What is […]
