Toxic or harmful best describes two substances that react to form salt.
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: I think the first option is the best option because water isn't a heat conductor and all the other options are not very accurate.
Explanation:
Answer:
<u>Speed = 1.2 m/s</u>
Explanation:
<em>Convert 20 min into seconds</em>
<em>1min= 60sec</em>
20min = 20*60 sec
<em>20 min= 1200sec</em>
Time = 1200 sec
Distance = 1000m
Speed =
Speed =
<u>Speed = 1.2 m/s</u>
<u></u>
