The 8 moon phases in order are New moon, Waxing Crescent, First Quarter, Waxing Gibbous, Full moon, Waning Gibbous, Third Quarter, and finally Waxing Crescent.
Before a star is born, the matter that will become the star exists as a interstelar gas and dust. The stars are formed as a result of the forces:the force of gravity compresses atoms in the interstellar gas. Then the fusion reaction begins. During this fusion reaction the temperature gets extremely high and all the material evolves into a hot bright star.

Answer:
k = 52.2 N / m
Explanation:
For this exercise we are going to use the conservation of mechanical energy.
Starting point. When it is 30 m high
Em₀ = K + U = ½ m v² + m g h
Final point. Right when you hit the water
= K_{e} = ½ k x²
in this case the distance the bungee is stretched is 30 m
x = h
as they indicate that there are no losses, energy is conserved
Em₀ = Em_{f}
½ m v² + m g h = ½ k h²
k =
let's calculate
k =
k = 52.2 N / m
