Question
Chapter 33, Problem 10RQ
To determine
The process that changes protostar to a full-fledged star.
Expert Solution & Answer
Answer to Problem 10RQ
The thermonuclear explosion causes a star to born from a protostar.
Explanation of Solution
The nebula contracts gravitationally, and it spins more rapidly, flattens and hats up at its centre. Then, a protostar is born from the hot central bulge. The thermonuclear explosion causes a star to born from a protostar.
In a thermonuclear explosion, the temperature exceeds 100 million. This temperature is needed for hydrogen fusion to take place effectively.
The time from a protostar to star is not same for all the stars but depends on the mass of the star. The more massive a star, the more rapid the process will be. Collapsing into a star-like Sun takes 50 million years. The collapsing of a protostar which has high mass might take only a million years whereas, smaller stars can take more than a hundred million years.
Conclusion:
Therefore, the thermonuclear explosion causes a star to born from a protostar.

- Namor, from Wakanda Forever, sits on a throne at the bottom of the ocean in a city called Talocan (and Atlantis in the comics). Assuming he, including his gold headdress, has a density of 1085 kg/m3 and that Namor is surrounded by salt water with a density of 1027 kg/m3, what is Namor’s normal force while sitting underwater?

Given that the air pressure above the portal is 1.013 ⋅10^5 Pa, what is the pressure when they are 3440. ft deep? 1 m = 3.28 ft. Moana would have a surface area of 1.30 m2.
