As the Sun ages, what will happen to life here on Earth? Why?

1 answer:

3 0

<span>Our Sun will slowly get hotter as more and more Helium accumulates in the Sun's core. In ~1 billion years, liquid water will no longer be possible on Earth's surface, and the oceans will completely boil away, resulting in a Venus-like planet. Only thermophyllic bacteria may be able to survive, perhaps at the poles. In ~4-5billion years, our Sun will have converted ~10% of its Hydrogen to Helium, and thus become so hot that Helium to Carbon fusion will begin in earnest, causing the "Helium flash" which will convert our Sun into a red giant, and swallow and vaporize all of the rocky inner planets. It may even blow off a planetary nebula. (Contrary to what the others have said, our Sun will not 'run out' of Hydrogen.) </span>

If you are under 13 can you still play The Isle? Are they going to make a kid version?

IgorC [24]

Answer:

I'm not quite sure, but rating wise, you should be able to play a game like 'The Isle' under adult supervision. But then again I also believe you must be 15+ to play, ACCORDING TO STEAM. and I highly doubt they will create a kids version. They'd have to develop a completely separate game, which has the possibility of being a complete waste of time.

A ball is thrown at the ground from the top of a tall building. The speed of the ball in meters per second is v(t)=9.8t+v0, were

EleoNora [17]

Answer:

$V_0=2.7m/s$

Explanation:

The speed of the ball in meters per second is

$V(t)=9.8t+V_0$

Where t denotes the number of seconds since the ball has been thrown and $V_0$ is the initial speed of the ball. Then:

$V(2)=9.8(2)+V_0\\\\V(2)=19.6+V_0$

If the ball travels 25 meters during the first 2 seconds after it is thrown, what was the initial speed of the ball

Also, for constant acceleration motion, the average velocity is equal to the sum of final and initial velocities divided by 2 and to the distance divided by the time:

$\dfrac{V(t)+V_0}{2}=\dfrac{d}{t}$

Where you know:

t = 2s

$V(2)=9.8(2)+V_0=19.6+V_0$

d = 25m

Substituting (the units are ommited in the equationn, but added at end of the answer):

$\dfrac{V(2)+V_0}{2}=\dfrac{25}{2}$

$V(2)+V_0=25$

Thus, you have a system of equations:

$V(2)+V_0=25$

$V(2)=19.6+V_0$

Substituting the second into the first:

$19.6+V_0+V_0=25\\\\19.6+2V_0=25$

$2V_0=25-19.6\\\\V_0=5.4/2\\\\V_0=2.7m/s$
