1. Air pollution is a problem<span> because it can cause damage to animals, trees, plants, crops and water sources in the environment. </span>Pollution<span> in the </span>air<span> causes </span>problems<span> for aviation because it reduces visibility, while also being responsible for damaging buildings and other structures.
2. </span><span>The air we breathe has a very exact chemical composition; 99 percent of it is made up of nitrogen, oxygen, water vapor and inert gases. Air </span>pollution occurs<span> when things that aren't normally there are added to the air. A common type of air </span>pollution<span>happens when people release particles into the air from burning fuels.
3. </span>Pollution prevention (P2) is any practice that reduces, eliminates, or prevents pollution at its source. ... Reducing the amount of pollution produced means less waste to control, treat, or dispose of. Less pollution means less hazards posed to public health and the environment.
4. Why is it so important to have clean air?
Answer:
The object is moving at constant speed.
Explanation:
The spaces between the dots are equal.
The true answer is the choice A
Scientists <span>can predict volcanic eruptions as long as adequate resources are available.Volcanic eruptions are one of the earthly activities which can be predicted by means of adequate resources (w</span><span>arming of the earth's crust, appearance of volcanic lava etc...). By contrast, earthquakes is a dangerous natural </span>disaster<span> that scientists cannot be predicted or mastering the time where it occurs.</span>
According to Newton's 3rd law, for every force applied, there's an equal and opposite force that will occur. So when you are walking , you are pushed forward but the plain is "pushed back" from the force
Explanation:
- A force is a push or a pull that acts upon an object as a results of its interaction with another object. Forces result from interactions.
- The statement means that in every interaction, there is a pair of forces acting on the two interacting objects. The size of the forces on the first object equals the size of the force on the second object. The direction of the force on the first object is opposite to the direction of the force on the second object. Forces always come in pairs - equal and opposite action-reaction force pairs.
- According to Newton, whenever objects A and B interact with each other, they exert forces upon each other.
- A variety of action-reaction force pairs are evident in nature.
