Speed is measured as the ratio between the distance and time and the SI unit of speed is m/s. It is the change in the position of an object with respect to time. There are four types of speed: uniform speed, variable speed, average speed, and instantaneo
the clouds and the surface is very long and the speed of light is much faster than the speed of sound hence lightning can be seen before the thunder is heard. you must know that the lightning frequency is around 40-50 times a second on earth. to know more about this, log on to our...
Speed measures the how fast an object is moving, which is determined by how much distance it travels over an amount of time. Its SI units are m/s (meters per second), however if you use other units in your calculations, the units can be different. A common example of speed meas...
Why reprex? Getting unstuck is hard. Your first step here is usually to create a reprex, or reproducible example. The goal of a reprex is to package your code, and information about your problem so that others can run it…
The ballots have to be quite sturdy to withstand the punishment of being put through high speed counting machines. The chads that are falling off are ones where the chad is already partially detached. I can assure you that the people who are counting these ballots by hand are treating the ...
In the Anthropocene, the era when the imprint of humans on nature is pervasive across the planet, it is of utmost importance to understand human relationships with other species. The aesthetics of nature, and of species, is one of the values that plays a
While the project is still ongoing, I can say that I am quite satisfied with the progress accomplished to date, and that many of my hopes for such a project have already been realized. On the scientific side, we have discovered some new techniques and constructions to show that a given eq...
