Answer:
correct answer is C
Explanation:
In this exercise, you are asked to complete the sentences so that the sentence makes sense.
1) in projectile launching, the only force that acts is gravity in the vertical direction, so the time of going up is EQUAL to the time of going down
correct answer C
2) when a body falls freely, the acceleration is the ratio of gravity, therefore if it starts from rest, its height is
y = v₀ t - ½ gt²
v₀ = 0
y = -1/2 g t²
so the position is not proportional to the square of the time
correct answer is C
Since each serves a different purpose, theories cannot become
laws. Explaining how or why a natural phenomenon occurs is what the set of ideas
called theories do. On the other hand, mathematical relationships that
describes what happens are what is done by laws.
Let me show an example that illustrates the points.
Describing what happens in the natural world are done by the mathematical
formulas called the Gas Laws. In this example, it would show that by using the
Gas Laws, I will be able to predict with great accuracy the pressure if I
double the temperature of a sealed gas. This idea is a law since the
relationship is mathematical and it tells us what will happen.
<span>On the other hand, in order to explain why gases behave like
the way they do, we must use the kinetic molecular theory.</span>
The middle ear transmits sound from the outer ear to the inner ear. The middle ear consists of three bones: the hammer (malleus), the anvil (incus) and the stirrup (stapes), the oval window, the round window and the Eustrachian tube. its called tympanic cavity
hope this helps :)
Good question because although this earth going through hell the earth will never break because its solid
Tbh I don’t know how earth is still put together after so much effect
