The sound intensity level of 100 physics professors talking simultaneously is equal to 72 decibel.
<u>Given the following data:</u>
- Sound intensity = 52 dB.
Sound intensity can be defined as a measure of the power of a sound wave per unit area. Thus, sound intensity is a quantity that can be used to measure the energy of sound and its unit of measurement is Watts per square meter.
<h3>How to calculate the sound intensity level.</h3>Mathematically, sound intensity level is given by this formula:
<u>Note:</u> The reference value of sound intensity is equal to
Thus, the sound intensity for one (1) professor is given by:
For 100 professors, the sound intensity is:
Substituting the parameters into the formula, we have;

Answer: The gravitational acceleration on planet X is 5 N/kg
On Earth (with the gravitational accelartion g_E) the mass of 2kg will correspond to
On planet X we are told the same measure is only 10N. Since there is a proportional relationship between g and F, we can calculate g_X:
