What are the uses of logarithmic scales?
From the Wikipedia article (link below), Presentation of data on a logarithmic scale can be helpful when the data cover a large range of values - for the use of the logarithms of the values rather than the actual values reduces a wide range to a more manageable size.
What is the difference in the Natural Logarithmic Function and the Common Logarithmic Function?
Natural logarithms use base e (approximately 2.71828), common logarithms use base 10.
How many different scales are available for a scale drawing?
Infinitely many. You can represent any distance in real life by 1 unit on your scale or, conversely, you use any distance on your scale drawing to represent a unit of length in real life.
How do you use real numbers in real world situations?
Unless you are an electrical engineer or a math teacher, every number you will ever use in a real world situation will be a real number.
How can the distance of a toy car travels down a ramp affect its speed be used in real world uses?
Physicists and Engineers use small scale models like this all the time to convert to real world use. A toy car going down a ramp can simulate how a life size car will respond going down a hill. They can then use that information to build safer roads and vehicles.
What type of scale does a Richter scale use?
a logarithmic scale
What is an example from real life where you would want to use a logarithmic equation?
If by "real life" you include the physical world, then you express the spontaneous decay of radioactivity in a sample with a logarithmic equation.
When would you not use logarithmic scale?
When dealing with farm animals
How do fractals and logarithms relate to the real world?
Many things in the real world are approximately fractal or logarithmic. For example, if you examine a shore line it will be a wriggly line. Examine it at more detail and you will see a similar pattern but at a smaller scale. Even more detail and you still have the same (or similar) pattern at yet more detail. Computer-aided graphics use this property to generate landscapes: storing a small amount of "data" and replicating it at different scales is far easier than storing masses of data. The logarithmic function also has this scale-invariant property. If you are interested, read the attached link about Benford's Law. The article does not require much mathematical knowledge - only curiosity.

How is the pH scale similar to the Richter scale?
Both the pH scale and the Richter scale are logarithmic scales used to measure specific properties - pH measures the acidity or alkalinity of a solution, while the Richter scale measures the magnitude of earthquakes. Both scales use logarithms to compress a wide range of values into a more manageable scale for easy comparison. Additionally, both scales are open-ended, meaning there is no upper limit to the values that can be recorded.
How long have map scales been used?
Unless you drew the map at full scale (real world size) all maps use a scaling factor of area of the real world to an area of the map. For example, on a 1:175,000 scale map one cm on the map represents 175,000 cm or 1.75 km (~1 mile) in the real world.
What scale does Japan use to measure earthquakes?
Japan uses the Richter scale to measure earthquakes. This scale quantifies the energy released by an earthquake using a logarithmic scale from 1 to 10. In addition to the Richter scale, Japan also uses the Japan Meteorological Agency (JMA) seismic intensity scale to evaluate the intensity of shaking felt at specific locations.
What do you mean by loudness of sound?
Loudness of sound refers to the perceived intensity or volume of a sound wave. It is measured in decibels (dB) and is influenced by the amplitude of the sound wave. The greater the amplitude, the louder the sound.
How do you draw a log graph?
You can get semi-log or log-log graph paper. In the first, the horizontal axis is linear while the vertical axis has a logarithmic scale. You can always use the paper sideways so that the horizontal is logarithmic and the vertical linear. The second type has both axes with logarithmic scales. Alternatively, you calculate the appropriate values and plot the results using the usual Cartesian coordinate system.
Why you use semi-log graph instead of simple graph?
A logarithmic scale is a scale of measurement that displays the value of a physical quantity using intervals corresponding to orders of magnitude, rather than a standard linear scale.A simple example is a chart whose vertical axis has equally spaced increments that are labeled 1, 10, 100, 1000, instead of 1, 2, 3, 4. Each unit increase on the logarithmic scale thus represents an exponential increase in the underlying quantity for the given base (10, in this case).Presentation of data on a logarithmic scale can be helpful when the data covers a large range of values. The use of the logarithms of the values rather than the actual values reduces a wide range to a more manageable size. Some of our senses operate in a logarithmic fashion (Weber-Fechner law), which makes logarithmic scales for these input quantities especially appropriate. In particular our sense of hearing perceives equal ratios of frequencies as equal differences in pitch. In addition, studies of young children in an isolated tribe have shown logarithmic scales to be the most natural display of numbers by humans.[1]
How can logarithms relate to everyday?
Before the invention of the calculator, people needed to perform math by hand. Using tables of logarithms greatly sped up the common tasks of multiplication, division, powers and roots. Today, people use devices or scales that are based on logarithms. Music volume is based on a logarithmic scale. Every time you turn the volume up, you are doing something based on logarithms. Earthquakes are based on a logarithmic scale. Every time that you hear about an earthquake on the news, the earthquake is described in reference to a scale based on logarithms. Earthquakes happen daily all over the world.
