We know the sun is primarily made from hydrogen and helium on the basis of its spectrum.
<h3>What is Sun's spectrum?</h3>
Sun's spectrum refers to the light of the Sun whose wavelength spectra can be used to identify atomic composition.
Thus spectrum (Sun's spectrum) initiates with the red light (700 nm) and ends with the blue (380 nm).
In conclusion, we know the sun is primarily made from hydrogen and helium on the basis of its spectrum.

Answer:
<h2>The answer is 40 N</h2>
Explanation:
The force acting on an object given it's mass and acceleration can be found by using the formula
<h3>force = mass × acceleration</h3>
From the question
mass = 50 kg
acceleration = 0.8 m/s²
We have
Force = 50 × 0.8
We have the final answer as
<h3>40 N</h3>
