How do you determine instantaneous speed? Instantaneous speed is found by taking the absolute value of instantaneous velocity, and it is always positive. Average speed is total distance traveled divided by elapsed time. The slope of a position-versus-time graph at a specific time gives instantaneous velocity at that time. What does instantaneous rest mean? It […]

How do I increase the resolution of my GC?
How do I increase the resolution of my GC? To improve the resolution of earlier eluting peaks, decrease the initial temperature or increase the initial hold time. Decreasing the initial temperature usually results in the largest resolution improvement, but analysis times are substantially increased (Figure 32a). What affects resolution in GC? Changes in resolution are […]
What is the smallest unbreakable unit of a compound?
What is the smallest unbreakable unit of a compound? molecule What are the similarities and differences of the two compounds? A compound contains atoms of different elements chemically combined together in a fixed ratio. An element is a pure chemical substance made of same type of atom. Compounds contain different elements in a fixed ratio […]
Why light shines off of a mirror?
Why light shines off of a mirror? A mirror is a surface that reflects light more perfectly than ordinary objects. Most objects reflect light at varying angles. This is more accurately called refraction, because the rays of light bend when they hit the object and move off in varying directions. This allows us to see […]
Which is best analog or digital?
Which is best analog or digital? Digital recordings can have a greater signal-to-noise ratio depending on the bit depth of the recording. This jump in elevation can create a digital noise. The smooth analog signal matches the recorded sound wave better than the steps of a digital recording. What are the three components of a […]
Is a woodchuck and a beaver the same thing?
Is a woodchuck and a beaver the same thing? The woodchuck and the beaver belong to the same rodent species, and are closely related to the squirrel family. Though they exhibit certain resemblance like the ever-growing teeth, gnawing habits, and ability to regulate temperature, there are a lot of differences in their habitats, breeding and […]
What would happen if there was no cryosphere?
What would happen if there was no cryosphere? In the Arctic, the decline of the cryosphere is affecting fundamental biological cycles like the reproduction of carbon-storing plankton. And it may also be affecting the jet stream, making weather more extreme across the Northern Hemisphere. Will there be another ice age? Researchers used data on Earth’s […]
What causes hydrogen gas to glow when an electric current is passed through it?
What causes hydrogen gas to glow when an electric current is passed through it? Terms in this set (62) What gives gas-filled lights their colors? An electric current passing through the gas in each glass tube makes the gas glow with its own characteristic color. These electrons lose energy by emitting light when they return […]
