Who invented scientific notation?
Rene Descartes in 1637. Archimedes created a similar system. <Original Answer> Archimedes. his exponential counting system created to help him calculate the amount of sand needed to fill the universe [in the Sand Reckoner]
How many grains of sand in a pound?
In your sand sample, what is the average weight of a grain?
How much area would a trillion grains of sand fill?
The area that a trillion grains of sand would fill depends on the size of the grains. On average, a grain of sand is about 0.5 millimeters in diameter. If we assume a density of about 1.6 grams per cubic centimeter for sand, a trillion grains would occupy approximately 0.5 cubic meters, which could cover an area of around 10 square meters to a depth of about 5 centimeters. However, this is a rough estimate and the actual area can vary based on grain size and packing density.
What is the independent variable in sand?
The independent variable in an experiment involving sand could be any factor that is intentionally changed or manipulated to observe its effect on another variable. For example, if you are studying how different grain sizes of sand affect water drainage rates, the grain size of the sand would be the independent variable. This is the variable that you control to see how it influences the dependent variable, which in this case would be the rate of drainage.
How much sand is required to construct 100 square feet?
The answer really requires a cubic measure - the volume - of the construction. 100 square feet can be covered to a depth of only a grain of sand or several inches (or more) of sand and, obviously, the quantity of sand required will vary accordingly.
What is the grain size of fine sand?
The grain size of fine sand typically ranges from 0.075 to 0.425 millimeters in diameter.
What is the diameter of meteorites?
The diameter of meteorites varies greatly, from the size of a grain of sand to the size of Mars (speculated).
Is a grain of sand macroscopic?
Yes, a grain of sand is considered macroscopic because it is large enough to see with the naked eye, typically measuring between 0.0625 to 2 millimeters in diameter.
Diameter of a human egg cell?
The diameter of a human egg cell is typically around 0.1 millimeters, which is roughly the size of a grain of sand.
What is a sand of sand called?
its called a sand dune.
Is an atoms or a grain of sand bigger?
Grain of sand is bigger
How do you measure the mass of a grain of sand?
This depends on the composition of the individual grain (which will effect it's density) and also on the size of the grain.Geologists and civil engineers split sand into 3 grades, from course (0.6 - 2 mm diameter), through medium (0.2 - 0.6 mm diameter) to fine (0.06 - 0.2 mm).As such sand is defined based on the size of the grains, not necessarily their composition. Sand grain composition can vary significantly however by far the most common mineral forming sand is quartz. Quartz has a density of 2650 kg / m cubed.As such a quartz sand grain may weigh as little as 0.007 grams and as much as 8 grams.
In which direction do you sand wood?
never sand wood across the grain always sand with the grain
Which direction do you sand wood?
never sand wood across the grain always sand with the grain
When was One Grain of Sand created?
One Grain of Sand was created in 1963.
When was Sand Grain Studios created?
Sand Grain Studios was created in 2002.
What is the state of matter for a grain of sand?
A grain of sand is a network solid (covalent network solid).
