Answer:
1: The formation of elements heavier than iron and nickel requires the input of energy. Supernova explosions result when the cores of massive stars have exhausted their fuel supplies and burned everything into iron and nickel. The nuclei with mass heavier than nickel are thought to be formed during these explosions.
Explanation:
2: The more luminous they are, the more reactions are taking place in their cores. Massive stars live shorter lives than the common small stars because even though they have a larger amount of hydrogen for nuclear reactions, their rate of consuming their fuel is very much greater.
Answer:
Explanation:
Solving (a): P(Joe)
To get this probability, we simply add up the items in the column named Joe.
These items are:
Joe: 34 and 70
And the total is:
The overall population of the system is:
So:
Solving (a): P(Joe and North Side)
To get this probability, we simply get the intersecting element of Joe column and North Side row.
From the table, the intersecting element is:
Joe and North Side: 70
The overall population of the system is:
