The noise from a power mower was measured at 104 dB. The noise level at a rock concert was measured at 121 dB. Find the ratio of

UkoKoshka [18]

Based on the calculations, the ratio of the intensity of Ir to Ip is equal to 50.12.

<h3>How to find the ratio of the intensity?</h3>

Let the intensity of the power mower be Ip.

Let the intensity of the rock music be Ir.

Mathematically, sound intensity level can be calculated by using this formula:

$\beta = 10 log(\frac{I}{I_{ref}} )$

<u>Where:</u>

I is the intensity of the sound.

Making I the subject of formula, we have:

I = Io × $10^{\frac{\beta }{10} }$

For Ip, we have:

Ip = Io × $10^{\frac{104 }{10} }$

Ip = Io × $10^{10.4}$

For Ir, we have:

Ir = Io × $10^{\frac{121 }{10} }$

Ir = Io × $10^{12.1}$

Now, we can find the ratio of the intensity:

Ir/Ip = Io × $10^{12.1}$ /Io × $10^{10.4}$

Ir/Ip = $10^{12.1}$ / $10^{10.4}$

Ir/Ip = $10^{12.1 -10.4}$

Ir/Ip = $10^{1.7}$

Ir/Ip = 50.12.

Which of the following has the highest viscosity? A. corn syrup B. milk C. water D. orange juice

snow_lady [41]

The correct answer for this question would be option A. Among the given options above, the one that has the highest viscosity would be corn syrup. When we say viscosity, this is the state of being thick, sticky and semifluid in consistency. Hope this is the answer that you are looking for.
