What does P in P wave stand for?
What does P in P wave stand for? Compressional waves are also called P-Waves, (P stands for “primary”) because they are always the first to arrive. Shear waves propagate more slowly through the Earth than compressional waves and arrive second, hence their name S- or secondary waves. What does V1 V2 V3 mean in ECG? […]
What if time was absolute?
What if time was absolute? Unlike relative time, Newton believed absolute time was imperceptible and could only be understood mathematically. Thus, every object has an absolute state of motion relative to absolute space, so that an object must be either in a state of absolute rest, or moving at some absolute speed. What is an […]
What decreases as elevation increases?
What decreases as elevation increases? As you increase in elevation, there is less air above you thus the pressure decreases. As the pressure decreases, air molecules spread out further (i.e. air expands) and the temperature decreases. How much does temperature change with elevation?

The intensity of light is inversely proportional to the square of the distance. This means that as the distance from a light source increases, the intensity […]
