Actually the greatest information we can extract from the
graph is that the lower the fossil is located beneath the rock, the older it
is. So we can see that fossil A is the oldest, trilobite and fossil B came
together, and fossil C is the youngest. From the choices, the answer is:
D. fossil B belongs to the same period as the trilobite
Answer: SBb
On 1930 the astronomer Edwin Hubble classified the galaxies based on their visual appearance into elliptical, spiral and irregular, being the first two classes the most frequent.
So, according to this classification, the Milky Way is a barred spiral galaxy (SBb in Hubble's notation system) because it has a central bar-shaped structure of bright stars that spans from one side of the galaxy to the other. In addition, its spiral arms seem to emerge from the end of this "bar".
Scientifics considered this, after measuring the the disk and central bulge region of the galaxy, and the conclusion is the Milky Way fulfills these conditions, because is a galaxy that orbits on its same axis and with this rotation its arms are twisted in opposite directions around the mentioned axis.
Answer:
Inertia: a tendency to do nothing or to remain unchanged; momentum:the quantity of motion of a moving body; velocity:the speed of something in a given direction; acceleration: a vehicles capacity to gain speed within a short time
<span>A battery is the power source for DC. (C)
You COULD use a battery to get AC, but you'd need some electronics,
to take the DC from the battery and use it to generate AC.</span>
