The answer is the last choice, the particle nature of light. The compton effect showed that a charged electron scatters the photon results in decreased energy but increase in wavelength.
The initial compression of the spring is determined as 0.54 m.
<h3>What is the compression of the spring?</h3>
The compression of the spring is determined by applying the principle of conservation of linear momentum as follows;
E = U
mgh = ¹/₂kx²
2mgh = kx²
x² = 2mgh/k
x = √(2mgh/k)
where;
- m is the mass of the projetcile
- h is the height
- k is the spring constant = 0.07 N/cm = 7 N/m
- x is the compression of the spring
x = √(2 x 0.021 x 9.8 x 5)/7)
x = 0.54 m

I believe the answer would be C.
Explanation:
What are the integers between -4 and +4?
The distance of the image formed is 44.27 cm and the magnification of the image is 0.7.
<h3>Location of the image</h3>
The image distance formed by the lens is calculated as follows;
1/v + 1/u = -1/f
where;
- v is the image distance
- u is the object distance
- f is the focal length of the lens
1/v = -1/f - 1/u
1/v = -(-1/26) - 1/63
1/v = 1/26 - 1/63
1/v = 0.022588
v = 1/0.022588
v = 44.27 cm
<h3>What is magnification of lens?</h3>
The magnification of a lens is defined as the ratio of the height of an image to the height of an object.
<h3>Magnification of the image formed</h3>
The magnification of the image is calculated as follows;
Magnification = image distance/object distance
M = 44.27/63
M = 0.7
Thus, the distance of the image formed is 44.27 cm and the magnification of the image is 0.7.
