Answer:
X has travelled 4 times as far as Y
X is moving 2 times as fast as Y
Explanation:
Because x=1/2at²(get rid of the first portion of x=vt+1/2at² because initial v is 0 which multiplies to 0). If the acceleration is set to for example 10 (keep this constant for both X and Y) and we use t=1 and t=2 for time (as the time travelled of X is twice that of Y). Plugging this into the equation, at t=1, x=4. At t=2, x=20. 20 is four times greater than 5, so X has travelled 4 times as far as Y.
To find the difference in speed between the two objects, use the equation . Since the initial velocity is 0, that part can just be removed from the equation. With v=at, it is easy to see that if the time plugged in is twice for one than the other (and the acceleration is the same for both), the final result will be twice of the other as well. For example: If the acceleration is 10 again for both, then v=10t. If t is 1, the velocity is 10. If t is 2, the velocity is 20.
Answer:
what chemicals are the sun made of
Like any star in its prime, the sun consists mainly of hydrogen atoms fusing two by two into helium, unleashing immense energy in the process. But it's the sun's tiny concentration of heavier elements, which astronomers call metals, that controls its fate.

The correct answer to public libraries response to to patrons’ increasing desire for e-books is; made a proactive change
<h3>What are proactive changes?</h3>
From the question we see that the public libraries have observed that patrons were now liking e-books more than print books. Thus, they are seeking to use technology to allow people to check out books on their mobile devices.
Now, this attitude of public libraries to allow patrons check out books on their mobile device is called being proactive. Thus, we can say that they made a proactive change by making changes in advance to suit the priorities of the users.
