Answer:
3rd law
Explanation:
First law of Newtons :
Newton's First Law states that, unless an external force acts on it, an object will remain in a straight line in rest or uniform motion.
The second law of Newtons :
The second law states that an object's acceleration depends on two variables-the net force that acts on the object and the object's mass.
The change in the linear momentum of the object is equal to the force.
Third law of Newtons :
This law states that every action has its reaction with the same magnitude but in the opposite direction.
When we push the wall , then the wall does not move because the wall is fixed but we skid opposite to the direction of applied force because wall offers an opposite force on our body.
Therefore the answer is "third law".
In a cornfield, only one plant species has dominated the area, that is the corn plant. While in a natural meadow, multiple species of plants occurs of different species. The presence of the different types of plants in the meadow will interact more number of insects in it as compared to the corn field. This will lead to more interactions among the different species in a natural meadow. The greater biodiversity of the natural meadow than the cornfield will support it better.
In case of any natural disaster, or a pest attack, all the plants will be killed in a corn field and so will the insects dependent on them, but in a natural meadow, if one plant species is killed by a natural disaster, other will still be alive. Hence, the ability to survive is greater in natural meadow.
Answer:
A hydrogen atom is made up of a nucleus with charge +1, and a single electron. Therefore, the only positively charged ion possible has charge +1.
