A fusion reaction takes place between carbon and another element. Neutrons are released, and a different element is formed. The
sdas [7]

Answer:

Dependent on the element that reacted with carbon

Explanation:

Nuclear fusion is the combination of small atomic nuclei into larger ones usually accompanied with the release of a large amount of energy.

From the problem stated, carbon fuses with another atom. The combined atom would have more nuclear particles in terms of protons and neutrons than the combining atoms. This will eventually make it weigh more than carbon and the atom it combines with. The resulting weight will depend on the combining atoms eventually.

There are four hundred participants in the local Thanksgiving 5K race. If 51% of the participants are female, what is the ratio
Paha777 [63]

Answer:

51:49 is the ratio of female participants to male participants.

Explanation:

Percentage of females in the race = 51 %

Percentage of males in the race = 100% - 51 % = 49%

Total participants in race = 400

Number of women participants = 51% of 400=\frac{51}{100}\times 400=204

Number of men participants  = 49% of 400=\frac{49}{100}\times 400=196

Ratio of female participants to male participants :

\frac{204}{196}=\frac{51}{49}=51:49
