No your answer is incorrect. Would you like the correct one?
True
Explanation:
It is correct to say that the salinity of the oceans has been relatively constant throughout geologic time because salt is removed at the same rate it has been added.
Salinity is the amount of dissolved salt found in the ocean. It is the degree of saltiness of the ocean.
- The rate at which salt has been added into the ocean over the years through geologic time has been very constant.
- Most salts in the ocean comes from land.
- Also the rate it has been removed is fairly constant.
- The salinity of ocean has once been used to date the age of the earth.

Answer:
Newton's Laws Applied to Collisions. Newton's third law of motion is naturally applied to collisions between two objects. ... Thus, if the colliding objects have unequal mass, they will have unequal accelerations as a result of the contact force that results during the collision.
Explanation:
Velocity = fλ
where f is frequency in Hz, and λ is wavelength in meters.
<span>2.04 * 10⁸ m/s = 5.09 * 10¹⁴ Hz * λ </span>
<span>(2.04 * 10⁸ m/s) / (5.09 * 10¹⁴ Hz ) = λ </span>
<span>4.007*10⁻⁷ m = λ </span>
<span>The wavelength of the yellow light = 4.007*10⁻⁷ m<span> </span></span>
Answer:
400 g
Explanation:
The computation of the number of grams in the original sample is shown below:
Given that
half-life = 5.26 years
total time of decay = 15.8 years
final amount = 50.0 g
Now based on the above information
number of half-lives past is
= 15.8 ÷ 5.26
= 3 half-lives
Now
3 half-lives = 1 ÷ 8 remains = 50.0 g
So, the number of grams would be
= 50.0 g × 8
= 400 g
