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:
<u>Where:</u>
I is the intensity of the sound.
Making I the subject of formula, we have:
I = Io × 
For Ip, we have:
Ip = Io × 
Ip = Io × 
For Ir, we have:
Ir = Io × 
Ir = Io × 
Now, we can find the ratio of the intensity:
Ir/Ip = Io × /Io ×
Ir/Ip = /
Ir/Ip = 
Ir/Ip = 
Ir/Ip = 50.12.

Try Socratic it helped me with this type of question
The frequency of the waves are 0,5
This is because the frequency of the wave is calculated by dividing the speed by the wavelength.
Answer:
Find the change in momentum of the upper stage, that is:
∆p = m(vf - vi)
m being the mass of the upper stage
vf being the final velocity which was given
vi being the initial which was also given
find ∆p
then use ∆p in the same equation
∆p being the answer you got above
m being the mass of the lower stage (given)
vi being the initial velocity (given)
vf being the final velocity of the lower stage which you were asked to find
Explanation:
During a collision the change in momentum (∆p) for both objects is equal regardless of their speeds or masses before or after the equation
