Answer:
True Explosion in antarctic sea ice levels may cause another ice age.
Explanation:
True
Using computer models, the studies show that a rise in sea ice may significantly change the ocean's circulation, ultimately resulting in a reversed greenhouse effect as ocean carbon dioxide rises and air levels decrease.
Some scientists at the University of Chicago said their analysis shows how the rise of Antarctic sea ice in cold climate could cause a cascade of shifts that could lead to turning the global climate towards glacial periods,
Answer:
the sun
Explanation:
the sun emits all types of electromagnetic radiation but a vast majority of it comes in the for of in the for of visible light ultraviolet rays and infrarays
The answer is 138.75 kgm/s
Impulse (I) is the multiplication of force (F) and time interval (Δt): I = F · Δt
It is given:
m = 0.25
F = 18,500 N = 18,500 kgm/s²
Δt = 0.0075 s
I = ?
I = F · Δt = 18,500 5kgm/s² * 0.0075 s = 18,500 * 0.0075 kgm/s² * s = 138.75 kgm/s
<h2>Answer: Medium
</h2>
The medium is the main factor that differentiates a mechanical wave from an electromagnetic wave, since the first can not propagate without its existence, while the second can propagate regardless of whether the medium exists or not.
In addition, it is the medium that will define, the propagation speed of the wave, according to its specific physical characteristics.
Therefore, the <u>correct answer</u> is a.
