Answer:
When x = 2.8 cm,
When x = 5.5 cm,
when x = 7.3 cm,
When x = 11.0 cm,
Explanation:
According to Biot-Savart law,
.......................(1)
R = 11.0 cm = 0.11 m
I = 17.0 A
N = 300 turns
When x₁ = 2.8 cm = 0.028 m
When x₂ = 5.5cm = 0.055 m
When x₃ = 7.3 cm = 0.073 m
When X₄ = 11.0 cm = 0.11 m
Answer:
The temperature required is near about 3 million kelvin
Explanation:
The brilliance of the star results from the nuclear reaction that take place in the core of the star and radiate a huge amount of thermal energy resulting from the fusion of hydrogen into helium.
For this reaction to take place, the temperature of the star's core must be near about 3 million kelvin.
The hydrogen atoms collide and starts and the energy from the collision results in the heating of the gas cloud. As the temperature comes to near about , the nuclear fusion reaction takes place in the core of the gas cloud.
The huge amount of thermal energy from the nuclear reaction gives the gas cloud a brilliance resulting in a protostar.
