Answer:
Explanation:
<u>Definition:</u> Noise pollution is generally defined as regular exposure to elevated sound levels that may lead to adverse effects in humans or other living organisms.
<u>Measures to be taken:</u>
- international bodies like the WHO agree that awareness of noise pollution is essential to beat this invisible enemy. For example: avoid very noisy leisure activities, opt for alternatives means of transport such as bicycles or electric vehicles over taking the car, do your housework at recommended times, insulate homes with noise-absorbing materials, etc. Educating the younger generation is also an essential aspect of environmental education.
- Governments can also take measures to ensure correct noise management .
- Close the Windows.
- Put on Earplugs. …
- Improve your Insulation. …
- Invest in Noise-Canceling Headphones. …
- Do Wall-to-Wall Carpeting. …
- Install a Fence. …
- Be Creative with the Office or House Layout. …
- Invest in Noise-Friendly Flooring..
Answer:
All the different habitats in our world make up biodiversity
Explanation:
Biodiversity is the sum of different species in life. With different species, it's diverse because it's more than one type.
Hope this helped!
20,000,000 kg*m/s
p=mv
10,000,000=m(v/2)
20,000,000=mv
Answer:
v = (78.0 i ^ - 70.27 j ^) m/s, v = 105 m / s
, θ = 318º
Explanation:
We have a projectile launch problem, let's start by calculating the time it takes to get through the canyon
y = t - ½ gt2
As the motorcyclist comes out horizontally, the speed he has is the horizontal speed (vox) and the initial vertical speed is zero (I go = 0)
y = 0 - ½ g t2
t = √ 2y / g
t = √ (2 252 /9.8)
t = 7.17 s
Let's calculate the vertical speed for this time
= - gt
= 0 - gt
= - 9.8 7.17
= - 70.27 m / s
We can give the result in two ways
First:
v = (78.0 i ^ - 70.27 j ^) m / s
Second:
using the Pythagorean theorem and trigonometry
v² = vₓ² + ²
v = √ [(78.0)² + (-70.42)²] = √ (11042.98)
v = 105 m / s
tan θ₁ = y / vₓ
tan θ₁ = -70.42 / 78.0
θ₁ = 42º
If we measure this angle from the positive direction of the x-axis counterclockwise
θ = 360 - θ₁
θ = 360 - 42
θ = 318º
I’m pretty sure it’s the green wire but I could be wrong
