Answer:
1. smaller objects cannot generate enough pressure to start hydrogen fusion.
2. 10,000,000
Explanation:
1. Stars are born in stellar nurseries known as nebula. A nebula is cloud of dust and gases. The disk of dust and gases when spins and gathers more and more mass, the temperature and pressure rises. If sufficient mass is gathered and right temperature and pressure is achieved fusion reaction starts and a star is born. Thus, smaller objects cannot generate enough pressure to start hydrogen fusion.
2. the core of a star must reach a temperature of <u>10,000,000</u> degrees Celsius for hydrogen fusion to begin.
Hydrogen fusion reaction in sun is:
Overall reaction for the above series of reactions is given by:
We will have the following:
First, the equation to use is the following:
Now, we transform the total distance the cat would need to travel:
So, the cat would need to travel 1.5 meters. ("d" in the equation).
Now, using the speed given we determine the time it would take the cat to traverse the 1.5 meters:
So, the time it would take the cat to traverse the distance will be approximately 3.33 seconds.
Now, we know that the acceleration will be given by Earth's gravity, so:
So, the initial vvelocity the cat must leave the floor in order to arrive at the butterfly with the optimum pouncing speed of 0.45 m/s is approximately 16.78 m/s or exactly 1007/60 m/s.
