Question

Chapter 12, Problem 1RQ

To determine

The main-sequence of the star.

Expert Solution & Answer

Answer to Problem 1RQ

A main sequence star is generated energy by fusion of hydrogen into helium in its core.

Explanation of Solution

In the H-R diagram, a star is located on the main-sequence. Get causally brighter with age.

That should be in Hydrostatic Equilibrium.
That should be in Thermal Equilibrium.
That should generate the energy by fusion of hydrogen into helium in its core.
These conditions are necessary, if not followed the star must left the main-sequence.

Gravity pulls each and every atom in a star towards the center, but its weight is balanced by the outward pressure of the hot gas which is inside the star. In that star, gases are heated by the nuclear reactions. The energy travels toward outside and its support the weight pressing down on it. At the beginning of the fusion, deuterium is burning.

Conclusion:

Therefore, a main sequence star is generated energy by fusion of hydrogen into helium in its core.

4 Problem 4) A particle is being pushed up a smooth slot by a rod. At the instant when 0 = rad, the angular speed of the arm is ė = 1 rad/sec, and the angular acceleration is = 2 rad/sec². What is the net force acting on the 1 kg particle at this instant? Express your answer as a vector in cylindrical coordinates. Hint: You can express the radial coordinate as a function of the angle by observing a right triangle. (20 pts) Ꮎ 2 m Figure 3: Particle pushed by rod along vertical path.
