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 […]
What arguments did Thomas Paine use in common sense to persuade the colonists to declare independence?
What arguments did Thomas Paine use in common sense to persuade the colonists to declare independence? Published in January 1776 in Philadelphia, nearly 120,000 copies were in circulation by April. Paine’s brilliant arguments were straightforward. He argued for two main points: (1) independence from England and (2) the creation of a democratic republic. What was […]
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 […]
How many days does a viral fever last?
What is the weight of a 0.2 kg mass?
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 […]
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 […]
What are 4 examples of potential energy?
What affects condensation?
What affects condensation? Two things must be present for condensation to occur: warm moist air, and cool surface temperatures below the dew point. The proper control of these two factors can minimize condensation. What is the main cause of condensation? Condensation occurs when warm air collides with cold surfaces, or when there’s too much humidity […]
