What happens when a protostar or star contracts under the influence of gravity?

Advanced Placement (AP)

AveGali [126]3 years ago
6 0

Answer:

As gravity compresses the core of a protostar, the temperature goes higher and higher. Eventually the temperature is high enough that the star starts fusing hydrogen into helium. When the outward pressure produced by the heating of the gas by fusion energy balances gravity, a stable star is formed.

Genrish500 [490]

Explanation:

The frictional resistance of the various pipes are given by the

K value in the table which may be used with the formula

hf = KQ2

to relate the magnitude of head loss hf in the pipeline

to the volumetric flow rate, Q. Water is drawn at the constant flow

rates from the network at nodes C and D. The static heads

(elevation + pressure head) at nodes B, C and D are 100m, 65m

and 61m respectively above the local datum. Calculate the

discharges at C and D and the water level in reservoir A. (The

data has been added to the diagram to aid the solution)

Use no more than 3 iterations and 3 significant figures.
