Answer:

The sun:

-is the largest star in our solar system

- is made mostly of hydrogen and helium  

-will eventually run out of fuel and die  

-creates energy through nuclear reactions

Explanation:    

The sun an average mass and sized star composed of hydrogen and helium gas. It generates energy in its core by nuclear fusion reaction. It is the only star in the solar system. Once all the fuel is run out, the nuclear fusion reaction would stop and the sun would die. There are billions of stars in our milky way galaxy and sun is not the largest of them.

My name is Ann [436]

Answer:

a)   C = 4,012 10⁻¹⁴ F, b)  Q = 1.6 10⁻¹¹ C , c)   U = 3.21 10⁻¹¹ J

Explanation:

a) The capacitance of a capacitor is

       C = k e₀ A / d

Let's calculate

       C = 4 8.85 10⁻¹² 17 10⁻⁴ / 0.150 10⁻²

       C = 4,012 10⁻¹⁴ F

b) let's look  the charge

        C = Q / ΔV

         Q = C ΔV

         Q = 4,012 10⁻¹⁴ 400

         Q = 1.6 10⁻¹¹ C

c) The stored energy

        U = ½ C ΔV²

        U = ½ 4,012 10⁻¹⁴  400²

        U = 3.21 10⁻¹¹ J
