Answer: As larger stars reach the red-giant phase, their temperature increases as helium is fused into carbon. Core temperature increases, with fusion forming oxygen, nitrogen and iron. When the star core converts to iron, fusion ceases.
Explanation:
Answer:
Workdone = 147Nm
Explanation:
Given the following data;
Mass = 5kg
Height = 3m
We know that acceleration due to gravity is 9.8m/s²
First of all, we would find the force applied;
Force = 5*9.8
Force = 49N
Now, to find the workdone;
Substituting into the equation, we have;
Workdone = 49 * 3
Workdone = 147Nm
