Prior to the discovery and elaboration of Copernicus with the theory of heliocentricism, which states that the sun is the center of the universe and that the planets orbit around it in a circular manner. The theory of geocentrism was first published by another astronomer and philosopher, Ptolemy. As a custom in the early years of the society, people already stood for the idea that the earth is the center of the universe which is easy to believe at that time given that their perspective shows that the sun moves when observed from earth's atmosphere.
Answer: B. have flowing water either episodically or during only a portion of the year
Explanation:
Ephemeral stream is a type of temporary stream that flows after rainfall or precipitation. Such streams are seasonal streams and are common in extremely dry or arid regions. This type of stream is not connected to any other water source either ground water or surface water except from rainfall, such streams ceases to flow after the raining season and dry off.
50 V. I don't know if this is correct, mainly because I'm in 7th grade.
<u>72 m</u> is the horizontal distance the travels.
Option: C
<u>Explanation</u>:
The units to express the horizontal and vertical distances are meters (m). The "horizontal" and "vertical" velocities are expressed in "meters per second" (m/s).
Horizontal distance = (initial horizontal velocity)(time)
We can now get the range x from the horizontal component of velocity
equation (1)
x = horizontal distance (m)
t = time (s)
We know that, V = 37 m/s, θ = 12 degree and t = 2 seconds.
To find,
x = 72.076 m ~ 72 m
x = 72 m
The horizontal distance is <u>72 m.</u>
