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:
1.41 m/s, 7.85 rad/s
Explanation:
We can start by calculating the tangential velocity, which is given by:
where
r = 18 cm = 0.18 m is the radius of the circumference
T = 0.8 s is the period
Substituting,
Now we can also calculate the angular velocity, which is given by:
where again,
T = 0.8 s is the period
Substituting,
Explanation:
A race car's main target is how to have rapid acceleration by scaling its speed. Acceleration of car is mostly a product of the force of the car engine.
According the newtons second law"The acceleration of body in motion depends on two main variables, the net force acting on it and the mass".
It is also written mathematically as:
F = m x a
F is the net force produced by the engine
m is the mass of the car
a is the acceleration.
Re-writing the equation:
Now Acceleration =
We can see that acceleration is directly related to increasing force but inversely proportional to the mass.
A race car needs to have a good acceleration so as to attain top speed.
The more the mass, the less the acceleration.
This is why extra weight like the seats are expunged.
