The answer is Helium Flash.
A helium flash marks the looming end of a red giant. As a red giant expands in its outer layers, its core is actually contracting. The core would eventually form a white dwarf.
As the core reaches a certain temperature, helium will start to fuse to form carbon. As this occurs, the fusing of helium, the core heats up. The core is not able to expand to cool down, so the reaction increases the core until the core will ultimately explode.
Answer:the H2O and O2 produced have the same mass as the original H2O2
<h2>
The speed of the rock just before it reaches the water 25.0 m below the point where the rock left your hand is 45.06 m/s</h2>
Explanation:
First let us find the initial velocity,
We have after 8 seconds the displacement is zero,
We have equation of motion s = ut + 0.5 at²
Initial velocity, u = ?
Acceleration, a = -9.81 m/s²
Time, t = 8 s
Displacement,s = 0 m
Substituting
s = ut + 0.5 at²
0 = u x 8 + 0.5 x -9.81 x 8²
u = 39.24 m/s
Initial velocity is 39.24 m/s.
Now this case is similar to case where a rock is thrown at 39.24 m/s downward.
We have equation of motion v² = u² + 2as
Initial velocity, u = 39.24 m/s
Acceleration, a = 9.81 m/s²
Final velocity, v = ?
Displacement, s = 25 m
Substituting
v² = u² + 2as
v² = 39.24² + 2 x 9.81 x 25
v = 45.06 m/s
The speed of the rock just before it reaches the water 25.0 m below the point where the rock left your hand is 45.06 m/s
Answer:
Spongebob: Bye Mr. Krabs! Bye Squidward! <em>BYE</em><em> </em><em>SQUIDWARD</em><em>!</em>
Patrick: (clearly triggered) <em>Why'd</em><em> </em><em>you</em><em> </em><em>say</em><em> </em><em>"</em><em>bye</em><em> </em><em>squidward</em><em>"</em><em> </em><em>twice</em><em>?</em>
Spongebob: <em>I</em><em> </em><em>LiKe</em><em> </em><em>SqUiDwArD</em>
Answer:
I think maybe D
Explanation:
A is wrong, it has to be reversed
B is wrong cause they connect at the poles
C is wrong cause they always point north (that's how compases work)
D is the only one that could be possible
Hope this helped! :D
