The correct answer is D. the star is getting farther away.
When the light has red-shifted, it shows that everything is moving away from a certain point. This is known as the Doppler effect and proves the Big Bang (which would be the center point that everything is moving away from). Just as a 'for your information', blue shift is when the star is moving towards us.

<h3><u>Mass of an object affect the outcome of unbalanced forces:</u></h3>
Newton’s second law of motion deals with the result of motion of an object when unbalanced forces are applied. The second law of motion establish the relationship between mass, acceleration and unbalanced forces of the object. The below points explains the relation between unbalanced forces acting on mass of the object. The acceleration of object would be higher when the unbalanced force is higher.
The equation for the unbalanced force is,

For Example: Two masses of 500 kg and 1 kg is applied with same unbalanced forces. The change in motion of 500 kg would be very much less than the change in motion of 1 kg.
It seems that you have missed the necessary options for us to answer this question so I had to look for it. Anyway, the answer to the given statement is FALSE. Pigments are NOT always made of natural materials. Pigments can either be man-made or the one that occurred naturally as what you see in our environment. Hope this helps.
Answer:
Shown from explanation.
Explanation:
The resonant frequency is related by the formula;
Fo= 1/2π√(K/M)
Where Fo is resonant frequency
M is mass
K is the spring constant
From the expression above;
When K is increased frequency would increases since frequency is directly proportional to spring constant.
Similarly when the mass is increased the frequency decreases since frequency is inversely proportional to the mass.
Amplitude is a property of a wave and so the frequency stays same.
