I would say that the first answer choice makes sense since the charge of Oxygen is +2. But I may be wrong, try it out!
Yes you are correct good job!
Each half-life results in ~50% (1/2) of the original element remaining.
7500/1250 = 6 half-lives, so 100(1/2)^6
= 100(0.015625)
= 1.5625% of the original element would remain
Answer:
<h2>Bernoulli’s Principle</h2>
This states principle helps explain that an aircraft can achieve lift due to the shape of its wings.
They wings are shaped that way so that that air flows faster over the top of the wing and slower underneath the wing .
In simple terms ;
Fast moving air equals low air pressure while slow moving air equals high air pressure
Explanation:
Same: Both are natural disasters. Both are becoming more common to due climate change.
Different: Floods are an excess amount of water whereas droughts are a lack of water for a prolonged period of time. Floods are more common in coastal areas whereas droughts are most common in the Midwest and South.
