Find the attachment for solution
I would say is b. The answer
Depth where light intensity falls to one percent<span> of that at the surface, called the euphotic depth</span>
Answer:
1.05 × 10⁻⁸ N
Explanation:
Using Coulomb's law
F force of attraction between them = k
= k 
K coulomb constant = 8.99 × 10⁹ N m²C⁻²
Z₁ = + 2 ( valency electron)
Z₂ = -1 ( valency electron)
r is the distance between then since they just touch one another = 0.085 nm + 0.125 nm = 0.21 nm = 0.21 × 10⁻⁹ m
q charge = 1.602 × 10⁻¹⁹ C of an electron
F = ( 2 × 1 × 8.99 × 10⁹ N m²C⁻² × (1.602 × 10⁻¹⁹ C)² / ( 0.21 × 10⁻⁹ m )² = 1046.34 × 10 ⁻¹¹ = 1.05 × 10⁻⁸ N
Answer:
<em>B. Female Merrick sea turtles begin returning to Bakerâs Beach to lay their eggs when they are ten years old.</em>
Explanation:
Firstly, There was an oil spill five years ago-no eggs hatched.
Now, the number of females coming back to the lay eggs has increased somewhat since the last five years.
The theory is that a period of 5 years is sufficient to assess effect on population.
If the breeding cycle has been found to be ten years long, then the impact of the oil spill on the population (as observed by the number of females returning to lay eggs) will only be perceived in the 10th year.
It undermines the argument that the oil spills don't impact the public.
