What happens to hydrogen in the core of stars

Physics
1 answer:
mezya [45]3 years ago
6 0
Stars burn by fusing hydrogen into helium. The process can be observed as if hydrogen is a fuel for the star. Thanks to the process, the stars release heat and light. When there's no more hydrogen, the star starts to grow smaller while its heat increases. Eventually, the star dies.

Answer:

Water breaking down into hydrogen and oxygen is a decomposition reaction

Hydrogen and oxygen combining to form water is a synthesis reaction

Explanation:

A decomposition reaction is a chemical reaction that involves the breakdown of a chemical reactant entity into two or more simpler product fragments

Water H₂O undergoes a decomposition reaction by breaking down into hydrogen, H₂,, and oxygen, O₂, as follows;

2H₂O (l) → 2H₂ (g) + O₂ (g)

A synthesis reaction is a reaction that involves the chemical combination of two or more dissimilar molecules or atoms to produce a different compound or molecule

Water, H₂O, is formed by a synthesis reaction of hydrogen, H₂,, and oxygen, O₂, combining as follows;

2H₂ + O₂  → 2H₂O

What is the period of a wave that has a frequency of 300 hz?
Butoxors [25]

Answer:

T = 0.003 s

(Period is written as T)

Explanation:

Period = time it takes for one wave to pass (measured in seconds)

frequency = number of cycles that occur in 1 second

(measured in Hz / hertz / 1 second)

Period : T

frequency : f

So, if we know that the frequency of a wave is 300 Hz, we can find the period of the wave from the relation between frequency and period

T =  \frac{1}{f}    f = \frac{1}{T}

to find the period (T) of this wave, we need to plug in the frequency (f) of 300

T = \frac{1}{300}

T = 0.00333333333

So, the period of a wave that has a frequency of 300 Hz is 0.003 s

[the period/T of this wave is 0.003 s]
