What is the mathematical formula to turn a particular sound frequency to a related color?
The formula to convert sound frequency to a related color is subjective and varies depending on the method used. One common method is to map frequencies directly to corresponding wavelengths within the visible light spectrum, with lower frequencies corresponding to longer wavelengths on the red end and higher frequencies to shorter wavelengths on the violet end. This method is often used in music visualization or sound-to-light systems.
1 gallon treats 2000 gallons how much will treat 30 gallons?
To find out how much of the solution is needed to treat 30 gallons, you can set up a proportion. Since 1 gallon treats 2000 gallons, you can set up the proportion: 1 gallon is to 2000 gallons as x gallons is to 30 gallons. Solving for x gives you x = (1/2000) * 30 = 0.015 gallons. Thus, 0.015 gallons of the solution would be needed to treat 30 gallons.
The accepted value for the boiling water is 100.0 degrees Celsius when you measure this value in the laboratory your result is 98.5 degrees Celsius What is the percent error?
The percent error is calculated by taking the absolute difference between the accepted value and the measured value, dividing by the accepted value, and multiplying by 100%. In this case, the absolute difference is 100.0 - 98.5 = 1.5. Dividing by 100.0 and multiplying by 100% gives a percent error of 1.5%.
How much electrical energy is used by a 75 W laptop that is operating for 12 minutes?
Any device that uses 75 watts will use 75 watt hours of electricity in one hour. In 12 minutes, 1/5th of an hour, it will use 75/5 or 15 watt hours of electricity. This is the same as .015 kilowatt hours of electricity.
