Answer:
His third law states that for every action (force) in nature there is an equal and opposite reaction. In other words, if object A exerts a force on object B, then object B also exerts an equal and opposite force on object A. Notice that the forces are exerted on different objects.
Explanation:
To answe this question, we will assume that the percentage abundance of 14n is y. Since the percentage abundance of 14n + percentage abundance of 15n = 100% = 1
Therefore, percentage abundance of 15n = 1 - y.
Now we know that the average atomic mass of nitrogen is 14.0067
Therefore:
average atomic mass of nitrogen = atomic mass of 14n x its percentage abundance + atomic mass of 14n x its percentage abundance
14.0067 = 14.003074002 y + <span>15.00010897 (1 - y)
</span>14.0067 = 14.003074002 y + 15.00010897 - 15.00010897 y
14.0067 - 15.00010897 = 14.003074002 y - 15.00010897 y
<span>0.99703497 y = 0.99340897
</span>
Therefore y = <span> 0.99636
Based on this, the percentage abundance of 14n is </span> 0.99636x100= <span>99.636%
while percentage abundance of 15n = 100% - </span>99.636% = <span>0.364%</span>
Orchids attract insects many different ways depending on the insect that they attract.
Orchids attract flies by using the smell of rotten flesh. Gross right?
Anyways another way they can attract insects is because of the shape of their petals. Some males insects think that their petals look like female insects and the male insect then lands on the petal and spreads pollen onto the flower
