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.

Answer:
Explanation:
This problem indicates that the speed of light in a material medium is 0.5 10⁸ m / s, they ask to find the critical angle between the material and the vacuum
Let's find the refractive index of the material
n = c / v
n = 3 10⁸ / 0.5 10⁸
n = 6
When the material passes from one medium to another, it must comply with the law of refraction
n₁ sin θ = n₂ sin θ₂
for the angle criticize the angles tea2 = 90
tea = sin⁻¹n₂/ n₁
The vacuum replacement index is n₂ = 1
tea = sin⁻¹ (1/6)
tea = 9.59º
The initial force between the two charges is given by:
where k is the Coulomb's constant, q1 and q2 the two charges, d their separation. Let's analyze now the other situations:
1. F
In this case, q1 is halved, q2 is doubled, but the distance between the charges remains d.
So, we have:
So, the new force is:
So the force has not changed.
2. F/4
In this case, q1 and q2 are unchanged. The distance between the charges is doubled to 2d.
So, we have:
So, the new force is:
So the force has decreased by a factor 4.
3. 6F
In this case, q1 is doubled and q2 is tripled. The distance between the charges remains d.
So, we have:
So, the new force is:
So the force has increased by a factor 6.
Answer:
The impact force is 98000 N.
Explanation:
mass = 10 tons
The impact force is the weight of the object.
Weight =mass x gravity
W = 10 x 1000 x 9.8
W = 98000 N
The impact force is 98000 N.
Answer:
option c
Explanation:
The temperature must be constant. Ohms law states that the current running through a conductor is directly proportional to the potential difference across it provided the temperature remains constant
