How do you know if two lines have the same velocity? Therefore, if the slope of the blue line is the same as the slope of the red line, then regardless of their relative positions on the graph, they have the same velocity. Does same position mean same velocity? So the slope of a position […]

Is radioactivity a spontaneous process? Radioactive decay is by definition a spontaneous process in which the nuclei of unstable isotopes emit radiation as they are converted to more stable nuclei. All the decay processes occur spontaneously, but the rates at which different isotopes decay vary widely. Does spontaneous mean random? As adjectives the difference between […]

Is Br2 bigger than i2? I2 has a higher boiling point than Br2. The atomic weights of Br and I are 80 and 127 respectively. Since I2 has higher molecular weight, it has stronger London dispersion forces so it has a higher boiling point than Br2. Why does I2 have such a high boiling point? […]

Why do you set the altimeter? Weather changes that affect temperatures and air pressures cause the complications in understanding and using an altimeter. This is why an aircraft’s actual height above mean sea level is its true altitude while what the altimeter says is the indicated altitude. Before going flying, you have to set the […]
