If sound intensity increases by a factor of 20, it increases 13 dB. Show an alternate way to derive the decibel (dB) increase (beyond simply using the formula from problem 1).

Problem Assignment Problem 1: What happens, in decibels (dB), when we multiply sound intensity by 10? Your answer here: the sound intensity changes by ______dB Write down the equation that shows how this works Problem 2: If we quadruple (multiply by 4) the intensity of a sound, what is the change in decibels? Your answer […]

Chapters 10 and 12 Written Homework Be sure to show all your work, particularly for odd-numbered questions. If you end up looking at a solution cite the source of your information. 10 – 26: The angular acceleration of a wheel, as a function of time, is 𝛼 = 4.2𝑑2 βˆ’9.0𝑑, where 𝛼 is in π‘Ÿπ‘Žπ‘‘/𝑠2 […]

From the friction force, determine the coefficient of kinetic friction for each trial and enter the values in the data table. Calculate an average value for the coefficient of kinetic friction for the block.

ASSIGNMENT A reliable indication that the experiments are of good quality is that results are consistent, meaning that different Trials of the same experiment give consistent results. Inspect your Data Tables to see if any of your experiments needs to be repeated to improve the quality. Inspect your force vs. time graph from Part I. […]
